Detailed view of Assets: Hosts and Business Processes

The Detailed view of Assets allows the user to directly access detailed, complete and up-to-date information about the items monitored in WOCU. All this information is displayed in seven sections (Status, Host, Services, Events, Metrics, Inventory and Edit) and is collected over the last 24 hours.

../../_images/2_033_aggregator_realm_assets_modal-host-view_0-57.jpg

This view is displayed in a pop-up window in front of the tab the user is in and is accessible from different parts of WOCU:

  1. From the Assets tab, in the Hosts and Business Processes inventories, by clicking on the name of the items within the Name column.

  2. From the Problems tab, in any of the views, by clicking on the name of the elements within the Name column in the Hosts or BP Hosts views or on the Host in the Services or BP Services views.

  3. From the Events Tab, in the Monitoring section, click on the name of the items within the Host column.

  4. From the Events Tab, in the Logs section, click on the Name that accompanies each of the Logs log entries.

  5. Desde la Pestaña Geomapa, haciendo clic sobre el nombre del Dispositivo (en color azul).

  6. From the Report management view, clicking on the name of the items inside the Host when generating a report view.

And more…

The different sections that make up this modal are described below:

Status

The Status tab of the Detail View provides accurate information on the status and configuration of the selected host. The data is displayed across six panes and is collected over the last 24 hours.

../../_images/2_034_aggregator_realm_assets_modal-host-status-tab_0-57.jpg

Attention

Only when the Host has Monitoring Packs associated, the system shall set in the upper header of the modal, identifying icons (of manufacturers, technologies, operating systems…) referring to these applied packs.

../../_images/2_067_aggregator_realm_assets_modal-host-icons-menu_0-50.jpg

The system will display a maximum of three icons ordered by a predefined weight scale, giving priority to the most representative and relevant (and least generic) icons/packs of the Host’s monitoring profile.

Placing the cursor over a particular icon will bring up a text alluding to the technology represented.

../../_images/46_19_icons_modal_view_info.png

More information can be found at: 2. Display icons identifying technologies associated with Monitoring Packs..

Host Status

This first panel indicates the operational status of the host and the monitoring checks carried out on it. It also provides other complementary data:

../../_images/2_034a_aggregator_realm_assets_modal-host-status-pannel_0-44.jpg
✓ Host IP address

Located above the state circumference.

✓ Current operational status of the host.

It is indicated inside the central circle. The possible states of a host are explained in detail in Statements of Assets in WOCU.

The rapid alternation of state changes in a host is known as Flapping. It is also represented on the panel by a yellow half-circle with a flashing grey arrow inside it.

../../_images/2_034b_aggregator_realm_assets_modal-host-status-flapping_0-44.gif
✓ State active time.

Indicates how long the current state has been active. In the image above, the host has been in the ‘UP’ state for thirty-seven seconds.

✓ Monitoring check.

WOCU performs checks to evaluate the operational status of the host. The half circle on the panel indicates whether the check option is activated or not (“On active checks” or “Off active checks”). In addition, the text to the right of the circle informs about the next check to be performed. In the previous image this functionality is activated, and the next check will be performed in twenty seconds (“Next check: 20 s”).

The option to disable host monitoring checks is accessible from the actions field, located in the Host Inventory of the Assets tab. To access the allowed options, simply click on the actions icon and a drop-down menu will display the option “Disable active checks for host and/or all services”.

../../_images/2_034c_aggregator_realm_assets_modal-host-status-disable-checks_0-36.jpg

Selecting this option will bring up a final window to confirm the Realm and Host for disabling checks. It is also possible to disable it for the services associated with the host, by checking the box “Apply to all services”.

../../_images/2_030t_aggregator_realm_assets_hosts-inventory-disable-checks_0-36.jpg

Related to the check task, this panel also provides complementary information about the types of statuses obtained and their level of severity, using the following labels:

  • Soft: is assigned when the host status obtained is not definitive, as it may or may not be reverted in the next check attempt. In the case of exceeding the predefined number of attempts, obtaining negative statuses, the error severity level will be raised to HARD type. The objective is to avoid false alarms due to transient problems.

    ../../_images/2_034e_aggregator_realm_assets_modal-host-status-hard_0-36.jpg
  • Hard: is assigned when the host status obtained is continuously erroneous, without being corrected. That is, when the host returns a negative status on the first attempt and also on subsequent checks, exceeding the predefined number of attempts. This new situation is notified to the contact user.

    ../../_images/2_034d_aggregator_realm_assets_modal-host-status-soft_0-36.jpg

✓ Data check and refresh button.

Button for refreshing and updating the data displayed in the panel. Clicking it will force an immediate refresh without waiting for the refresh scheduled in User preferences. This way you get a real-time view of the status of the Asset.

../../_images/2_034p_aggregator_realm_assets_modal-host-status-check-button_0-44.jpg

Note

Clicking on this panel will take you to the Host section.

Last check information

This panel reports the various checks performed on the selected host and the results obtained.

../../_images/2_034n_aggregator_realm_assets_modal-host-status-las-check-info_0-46.jpg

✓ Active checks: this field indicates whether active monitoring checks are enabled for this host: Yes (Yes) or No.

✓ Last time up: informs the user of the last time the host status was UP.

✓ Last hard state change: indicates how long ago (plus the date and time in parentheses) the last hard state change was (hard state change). This is an internal concept handled by WOCU and other monitoring systems: change from soft state to hard state. A confirmed state change implies the confirmation of the worsening or loss of availability of a host.

✓ Last check: indicates when the last check was performed on the host.

✓ Next check: indicates when the next check will be performed on the host.

✓ Check command: contains the operation performed internally by WOCU to determine the status of the host. Logically, the value of this field will vary depending on the type of host and its technical characteristics.

✓ Plugin output: contains the response obtained to the application of the check operation performed by WOCU.

RTA (last 24 hours)

This panel shows a graph with the Round-Trip Average of a Host (dark blue graph), as well as the percentage of lost packets (red graph).

../../_images/2_034f_aggregator_realm_assets_modal-host-RTA-pannel_0-38.jpg

The scale on the vertical axis of the graph indicates on the left the measured RTA value in milliseconds, as well as on the right the percentage of packet loss. The horizontal axis expresses the time (time within the last 24 hours).

Note

WOCU uses the ping tool to check if there is communication at Network level with the monitored hosts, sending messages (ICMP Echos). In addition to determining this connectivity, it is possible to measure the latency or the time it takes for the response messages to be received by the monitored hosts. By recording the response times of each host, WOCU builds the RTA checks graph. At the same time, the number of ICMP packets lost is analysed.

By hovering the cursor over the graph, the values for a particular point on the graph can be displayed. WOCU will indicate for the selected point, the RTA value in milliseconds, the Packet loss value in percent and the exact time of recording.

../../_images/2_034g_aggregator_realm_assets_modal-host-RTA-detail_0-38.jpg

Attention

Clicking on the graph will redirect the user to the Metrics section.

Availability(last 24 hours)

This panel has two graphical elements that provide information related to the availability level of a monitored host in WOCU.

../../_images/2_034h_aggregator_realm_assets_modal-host-availability-pannel_0-40.jpg

Semicircular graph


It represents the percentage of host availability reached in the last 24 hours. The percentage value is indicated inside the graph, together with the Threshold predefined by the user, which is also indicated on the graph with a dashed line.

Depending on the compliance or non-compliance with the minimum availability threshold, a green “✓” will appear in front of the availability percentage if the availability exceeds the set value, or a red “X” if it does not.

../../_images/2_034i_aggregator_realm_assets_modal-host-availability-grafic_0-40.jpg

Time bar


This time bar provides a history of the host’s availability over the last 24 hours, showing the exact moment or period of time when the host was not operational.

../../_images/2_034j_aggregator_realm_assets_modal-host-availability-grafic_0-40.jpg

The complementary legend informs about the period of time (in days, hours and seconds) of availability (green colour) and non-availability (red colour) of the host.

There is also the possibility that the system has not collected enough data to determine the initial state of a host. In this case, the user can assume and assign a starting status. This new status is also recorded and displayed in the time bar and in the legend:

Initial State: indicates the state defined by the user, for the time period to be assumed. This value is set in the User Preferences, specifically in the Status Initial SLA Host filter

Assumed time: indicates the total duration of the assumed event. In the example above, the total duration of this state has been five hours and twenty-eight minutes (in the last twenty-four hours).

Services

This panel shows, by means of the ring graph, all the services associated with the host (value indicated in the graph) and in which monitoring status they are in. The legend identifies each of the different states, along with the total number of services that reach that state.

../../_images/2_034k_aggregator_realm_assets_modal-host-services-pannel_0-38.jpg

Placing the cursor over a portion of the graph will display new pop-up information with the status, total number and percentage of services linked to it.

See the following example: 10 of the Host’s services (corresponding to 37.04% of the total) are in Warning status.

../../_images/2_034l_aggregator_realm_assets_modal-host-services-detail_0-38.jpg

Note

Clicking on this panel takes you to the Asset Detail View and BP tab: Services.

Top 5 monitoring events

This panel reports, through five bars, the most frequent types of Events in the last 24 hours for the selected host. Each of the bars represents a type of event and each bar indicates the number of times an event has occurred.

../../_images/2_034m_aggregator_realm_assets_modal-host-events-pannel_0-40.jpg

The different types of Events are explained in detail in the Event field of the Monitoring Event List Fields section.

Note

Clicking on this panel takes you to the section of the Asset Detail View and BP: Events.

Host

The Host tab of the Detail View provides accurate information about the configuration, properties and status of the selected host. The data is displayed through three main panes, explained below.

../../_images/2_035_aggregator_realm_assets_modal-host-tab_0-59.png

Attention

Only when the Host has Monitoring Packs associated, the system shall set in the upper header of the modal, identifying icons (of manufacturers, technologies, operating systems…) referring to these applied packs.

../../_images/2_067_aggregator_realm_assets_modal-host-icons-menu_0-50.jpg

The system will display a maximum of three icons ordered by a predefined weight scale, giving priority to the most representative and relevant (and least generic) icons/packs of the Host’s monitoring profile.

Placing the cursor over a particular icon will bring up a text alluding to the technology represented.

../../_images/46_19_icons_modal_view_info.png

More information can be found at: 2. Display icons identifying technologies associated with Monitoring Packs..

Host Info

This panel displays information about the host and its monitoring configuration. It consists of two parts:

Configuration


This part of the panel contains the basic attributes, defined when the host is registered in WOCU.

../../_images/2_035a_aggregator_realm_assets_modal-host-configuration-view_0-59.png

The fields in the Configuration are always the same for all hosts and are as follows:

Name: is the formal name or identifier of the host.

Address: is the Network or IP address of the host.

Alias: is the alternative name of the host.

Display name: this is the name by which the host shall be known in WOCU.

Contacts: these are the people in charge of managing the host to be contacted in the event of an incident.

Contact Groups: group of people who are in charge of the management of the host to be contacted in case of an incident on the host.

Member of: when a host belongs to one or several Hostgroups, this information shall be indicated in this field. It may happen that the available space is exceeded, in this case an ellipsis (…) is included to indicate that the text continues but has been cut. However, the list of Host Groups can be consulted by placing the cursor over this text. This field will not be visible when the host is not integrated in any group.

Business Impact: this field marks a value on a scale in scale (from 0 to 5) indicating the importance or significance of the that element. The values are:

  • None: 0 stars

  • Low : 1 star

  • Medium: 2 stars

  • High: 3 stars

  • Very High: 4 stars

  • Critical: 5 stars

Templates: this field contains a series of tags that inform the user of the configuration templates used and assigned to the host. Each of the tags corresponds to a Configuration Template applied.

Packs: this field contains a series of tags that inform the user of the configuration of the monitoring profile assigned to the host. Each of the tags corresponds to a Monitoring Pack applied.

Behaviour: this field contains the complete list of icons identifying technologies, manufacturers, usage patterns, etc., that are associated to Monitoring Packs. Remember that the system displays a maximum of three icons in the main header of the modal. Placing the cursor over a particular icon will pop up a text alluding to the entity represented.

Properties


Information regarding the configuration properties of the selected host. Each configuration variable is listed, as well as its values, which will vary depending on the type of host being monitored and the configuration profile set.

../../_images/2_035c_aggregator_realm_assets_modal-host-properties_0-46.jpg

Host Status

This panel displays information related to the operational status of the monitored Host. It consists of three parts:

Status


In this first part of the panel, an overview of the status of the host and its associated services is displayed.

../../_images/2_035d_aggregator_realm_assets_modal-host-status_0-41.jpg
  • State: indicates the current status of the Host and the last check performed.

  • Num services ok: indicates the number of services of the host in OK status.

  • Num services warning: indicates the number of services of the host in Warning state.

  • Num services critical: indicates the number of services of the host in Critical status.

  • Num services pending: indicates the number of services of the host in Pending status.

  • Num services unknown: Indicates the number of services of the host in Unknow state.

Performance


In this table, WOCU collects the monitoring metrics generated after the checks that the service launches on the Host on which it depends. Each metric records performance and capacity values, allowing a deeper analysis of the service, and consequently of the Appliance in terms of availability.

../../_images/2_035f_aggregator_realm_assets_modal-host-performance_0-41.jpg

Note

For more information, the user is referred to Performance, whose table is similar to the one shown in this view.

Geolocation Info

This last space shows a map with the exact geographic location of the monitored Host.

The map will be visible as long as the geographical coordinates of the Host have been included in its configuration. Otherwise, this element will be greyed out.

../../_images/2_035b_aggregator_realm_assets_modal-host-gemap_0-46.jpg

Services

Through this tab of the Detail View, WOCU lists the Services associated with the selected host, and the status of each of them.

../../_images/2_036_aggregator_realm_assets_modal-host-services-tab_0-57.jpg

Attention

Only when the Host has Monitoring Packs associated, the system shall set in the upper header of the modal, identifying icons (of manufacturers, technologies, operating systems…) referring to these applied packs.

../../_images/2_067_aggregator_realm_assets_modal-host-icons-menu_0-50.jpg

The system will display a maximum of three icons ordered by a predefined weight scale, giving priority to the most representative and relevant (and least generic) icons/packs of the Host’s monitoring profile.

Placing the cursor over a particular icon will bring up a text alluding to the technology represented.

../../_images/46_19_icons_modal_view_info.png

More information can be found at: 2. Display icons identifying technologies associated with Monitoring Packs..

This option provides the user with information similar to that provided by the Assets tab, once the host’s services are displayed. The fields available in the service listing table are explained in detail in Host Inventory Fields.

Therefore, the fields shown are practically the same, except for the following:

  • Graphics field: not present in this Detail View.

  • Field and icons of applied actions: not present in this Detail View.

  • Next Check field: present in this Detail View and not in the Assets Tab.

  • Actions field: not present in this Detail View.

Important

The different navigation, search and sorting options available on this screen are explained in detail in the section: Common navigation, filtering and sorting options in WOCU.

Events

The Events of a host are stored and presented in this tab. All event messages produced for the selected host are displayed. These are separated into two sections:

../../_images/2_037_aggregator_realm_assets_modal-host-events-tab_0-57.jpg

Attention

Only when the Host has Monitoring Packs associated, the system shall set in the upper header of the modal, identifying icons (of manufacturers, technologies, operating systems…) referring to these applied packs.

../../_images/2_067_aggregator_realm_assets_modal-host-icons-menu_0-50.jpg

The system will display a maximum of three icons ordered by a predefined weight scale, giving priority to the most representative and relevant (and least generic) icons/packs of the Host’s monitoring profile.

Placing the cursor over a particular icon will bring up a text alluding to the technology represented.

../../_images/46_19_icons_modal_view_info.png

More information can be found at: 2. Display icons identifying technologies associated with Monitoring Packs..

List of Monitoring Events

This section shows the monitoring events of a host, produced in WOCU in the last 24 hours.

../../_images/2_037a_aggregator_realm_assets_modal-host-events-monitoring_0-57.jpg

This list provides the user with information similar to that provided in the Events section, for a given realm. Therefore, the fields available in this table are explained in detail in Monitoring Event List Fields.

Other Log Events (Logs)

This section shows other external event messages, independent of WOCU events, but which may be useful in monitoring tasks. That is, all logs (except monitoring logs) generated in the last 24 hours are displayed.

../../_images/2_037b_aggregator_realm_assets_modal-host-events-logs_0-57.jpg

This listing provides the user with information similar to that provided in the Events section, for a given realm. Therefore, the fields available in the log table are explained in detail in Log Event List Fields.

Important

The different navigation, search and sorting options available on this screen are explained in detail in the section: Common navigation, filtering and sorting options in WOCU.

Metrics

The Metrics tab provides accurate information about the selected Host’s performance, by means of performance values collected by WOCU and stored in metrics during a check. They are visualised in graphs showing data collected over specific time periods, as well as indicating defined Warning and Critical status thresholds.

../../_images/2_038_aggregator_realm_assets_modal-host-metrics-tab_0-59.png

Attention

Only when the Host has Monitoring Packs associated, the system shall set in the upper header of the modal, identifying icons (of manufacturers, technologies, operating systems…) referring to these applied packs.

../../_images/2_067_aggregator_realm_assets_modal-host-icons-menu_0-50.jpg

The system will display a maximum of three icons ordered by a predefined weight scale, giving priority to the most representative and relevant (and least generic) icons/packs of the Host’s monitoring profile.

Placing the cursor over a particular icon will bring up a text alluding to the technology represented.

../../_images/46_19_icons_modal_view_info.png

More information can be found at: 2. Display icons identifying technologies associated with Monitoring Packs..

The selectors available on the graph allow:

Selection of a date range for displaying the data

By default it is set to 1 day, but there are other time criteria to choose from, such as: 4 hours, 1 week, 1 month, 1 year and Custom Range.

../../_images/2_038a_aggregator_realm_assets_modal-host-metrics-range_0-36.jpg

In case you want to set a specific period of time there is the option Custom Range. To configure the time frame it is necessary to set a start date and an end date. By clicking on one of the days, this date will be set as a selection, being marked with a blue background. In addition to the day, a specific time can be set for that day. To do so, use the drop-down menus in the hour, minute and second boxes to set the desired time.

Attention

It is of course not possible to choose start and end dates after the current date, nor to set an end date before the start date.

Selection of the metric whose information is to be displayed

  • RTA (Round-Trip Average) metric: applied by default. Displays the round-trip times of the Host. The vertical axis scale indicates the unit in which the metric is measured, in this case, milliseconds (ms). The horizontal axis is configured according to the chosen time unit.

../../_images/2_038b_aggregator_realm_assets_modal-host-metrics-rta_0-57.jpg
  • PL (Packet loss) metric: shows the percentage of packets lost. The scale on the vertical axis of the graph indicates the unit of measurement, in this case in percentage (%). As in the previous metric, the horizontal axis is configured according to the chosen time unit.

../../_images/2_038c_aggregator_realm_assets_modal-host-metrics-pl_0-57.jpg

Note

Thanks to the three-colour legend, it is easy to identify the values of both the metric and the thresholds of status change: Warning (yellow) and Critical (red). In addition to the legend, the maximum (max), average (avg) and last recorded values are also provided.

../../_images/2_038d_aggregator_realm_assets_modal-host-metrics-detail_0-59.png

Interval selection of a metric in the graph itself

In addition to being able to select (pre-set) time ranges for particular metrics, it is possible to manually select intervals and sub-intervals in the data series and to display a graph of these intervals and sub-intervals.

The selection will be made directly on the graph itself using the mouse. To do this, it is necessary to place the mouse in the area of the generated graph. By clicking and dragging with the left mouse button, a sub-interval within the interval we are visualising will be selected.

Once the range has been selected, we can release the left mouse button, which will result in the graph being updated to show only the defined range.

../../_images/2_038e_aggregator_realm_assets_modal-host-metrics-portion-selection_0-59.png

In addition, in the upper date range bar, the time period corresponding to the manual selection applied shall be specified.

../../_images/2_038f_aggregator_realm_assets_modal-host-metrics-portion-info_0-59.png

To go back to the initial graph (according to the previously chosen range), the filter has to be re-applied and the displayed data will be restored.

Note

This action can be repeated indefinitely, each time obtaining a smaller selected range than the previous one.

Inventory

The Inventory tab of the Detail View collects and provides technical information about the selected Host. Hosts are registered in inventories, where each of them is enriched with technical data.

../../_images/2_039_aggregator_realm_assets_modal-host-inventory-tab_0-57.jpg

Attention

Only when the Host has Monitoring Packs associated, the system shall set in the upper header of the modal, identifying icons (of manufacturers, technologies, operating systems…) referring to these applied packs.

../../_images/2_067_aggregator_realm_assets_modal-host-icons-menu_0-50.jpg

The system will display a maximum of three icons ordered by a predefined weight scale, giving priority to the most representative and relevant (and least generic) icons/packs of the Host’s monitoring profile.

Placing the cursor over a particular icon will bring up a text alluding to the technology represented.

../../_images/46_19_icons_modal_view_info.png

More information can be found at: 2. Display icons identifying technologies associated with Monitoring Packs..

The data for each of the hosts are records in a series of fields described below:

  • Section: Sections are different inventory categories, which encompass hosts according to a set of technical characteristics.

  • Key: Keys are sub-sections that take inventory values, for a monitored host.

  • Value: values taken by a key, from a given section.

Important

  • The corresponding Sections, Keys and Values are created and configured by the Administrator.

  • It is possible to assign inventories to hosts from the administration interface and through the use of the API.

Note

The different navigation, search and sorting options available on this screen are explained in detail in the section: Common navigation, filtering and sorting options in WOCU.

Edit

The Edit tab of the Detail View allows the user to make changes to the configuration of the Hosts and Business Process Hosts monitored in WOCU.

../../_images/2_040_aggregator_realm_assets_modal-host-edit-host-tab_0-57.jpg ../../_images/2_040a_aggregator_realm_assets_modal-host-edit-bp-tab_0-36.jpg

Important

The Edit tab will only be visible and accessible from standard Realms, i.e. it will be hidden for Realms based on Hosts Groups and Multirealm.

Attention

Only when the Host has Monitoring Packs associated, the system shall set in the upper header of the modal, identifying icons (of manufacturers, technologies, operating systems…) referring to these applied packs.

../../_images/2_067_aggregator_realm_assets_modal-host-icons-menu_0-50.jpg

The system will display a maximum of three icons ordered by a predefined weight scale, giving priority to the most representative and relevant (and least generic) icons/packs of the Host’s monitoring profile.

Placing the cursor over a particular icon will bring up a text alluding to the technology represented.

../../_images/46_19_icons_modal_view_info.png

More information can be found at: 2. Display icons identifying technologies associated with Monitoring Packs..

The fields to edit coincide with those described in Add Host and Add Business Process Host (Add HBP) Once the data in the corresponding fields have been modified, the blue button Edit Host or Edit HBP must be clicked to save the configuration made so far, and the form can continue to be edited. Finally, any change in the Asset configuration will be consolidated in WOCU through the execution of WOCU Check.

../../_images/2_040b_aggregator_realm_assets_modal-host-edit-save-button_0-36.jpg

Warning

The system shall return an error when saving the edit, when the Host has been previously deleted from the Import Tool and the WOCU Check action has not been executed to make the final deletion of the Host effective.

../../_images/2_040c_aggregator_realm_assets_modal-host-edit-error_0-36.jpg

This lack of synchronisation between the import module and the editing module will cause an error preventing the modification of the asset, as it will not be detected as a member of any realm.

BP Trace

The BP Trace tab, visible only in the Detailed view of Assets: Hosts and Business Processes tab, shows the user a tree traced from a previously defined Business Rule (BP Rule) of Assets. Thanks to the representation with nodes and logical relationships, in addition to knowing the state of the Business Process, the user will be able to analyse and locate the root cause of an anomalous monitoring state.

../../_images/2_041_aggregator_realm_assets_modal-host-BP-trace-tab_0-43.jpg

Remember

Having established the Business Rule, WOCU-Monitoring will first evaluate the status of each Business Process element. Then, taking into consideration these individual states and the logical operators that link and relate the elements of the Business Process, the system will calculate and determine a state for the Business Process.

On the other hand, the system only considers states of type HARD to determine the overall state of the node. Therefore, any internal changes of type SOFT will be rejected and will not affect the monitoring state calculation.

Attention

Only when the Host has Monitoring Packs associated, the system shall set in the upper header of the modal, identifying icons (of manufacturers, technologies, operating systems…) referring to these applied packs.

../../_images/2_067_aggregator_realm_assets_modal-host-icons-menu_0-50.jpg

The system will display a maximum of three icons ordered by a predefined weight scale, giving priority to the most representative and relevant (and least generic) icons/packs of the Host’s monitoring profile.

Placing the cursor over a particular icon will bring up a text alluding to the technology represented.

../../_images/46_19_icons_modal_view_info.png

Parts of the overview

1. Problematic Assets table

As the name suggests, this information table lists all assets that have a problem or failure, whether or not they are the cause of the total tree failure.

../../_images/2_041a_aggregator_realm_assets_modal-host-BP-trace-table_0-42.jpg

Each entry in the table records for a specific Host:

- Info column: contains a button (▼) enabled only in the entries for Hosts with associated Services. A new explanatory entry is displayed, detailing the reason or reason for the problem affecting that service and therefore, possible cause of the tree crash or instability.

../../_images/2_041c_aggregator_realm_assets_modal-host-BP-trace-error-info_0-42.jpg

- Host column: each row is an anomalous Host, which may or may not be the reason for the crash or total failure of the painted Business Process. The displayed name is determined by the value of the Display name attribute.

- Service column: service associated to a problematic Host.

- Status column: current monitoring status of the respective problematic Host.

- Failure Causes column: specifies whether this asset is causing the tree to fall (value = YES) or whether its problem is not affecting operational stability (value = NO).

In case the Business Process has an optimal monitoring status, this table will be hidden (no data) and the tree will be displayed clean.

../../_images/2_041b_aggregator_realm_assets_modal-host-BP-trace-ok_0-43.jpg

Important

As a special feature, please note that for duplicate problem nodes that are in the same situation, only a single entry will be recorded in the table. Remember that WOCU-Monitoring is able to process and render trees composed of several nested Business Processes (BP).

2. Business Process Tree

Tree representation of the Business Process Rule. This tree uses colour coding, shapes and labels to represent the status of each part of the process. The simplicity of this tree facilitates the analysis and immediate location of the root cause of the failure.

../../_images/2_041e_aggregator_realm_assets_modal-host-BP-trace-tree_0-43.jpg

Issues to consider

  1. The geometric shape of the nodes corresponds to their type. The types are:

  4. The colour of the tree nodes corresponds to their state:

    • Azul (Unknown)

    • Amarillo (Warning)

    • Rojo (Critical/Down)

    • Verde (UP/OK)

  5. The node corresponding to the Business Process rule (BP Rule) will always head the tree. Placing the cursor over the node name will display the business rule as a visual aid to understanding the mapped tree.

    ../../_images/2_041h_aggregator_realm_assets_modal-host-BP-trace-nodo-bp-rule-view_0-36.jpg
  6. The tree also supports nested Business Processes (BPs), i.e. BPs that integrate other BPs among their members, either BP Host or BP Services. This element is represented by a house symbol.

    ../../_images/2_041n_aggregator_realm_assets_modal-host-BP-trace-nodo-bp_0-39.jpg
  7. It is possible to expand and collapse nodes to make navigation through the tree more comfortable. To do this, just click on a specific node and the dependent nodes will be hidden, showing only nodes of hierarchical levels above it.

Tree display options

Hide table

The problem asset table can be hidden from view, leaving more space for the tree display. To do this, simply click along the dynamic bar attached to the right-hand side of the table. It will immediately be hidden, following the direction of the arrow inside it. To show the collapsed table again, click again on this same bar, whose arrow now points to the right.

../../_images/2_041i_aggregator_realm_assets_modal-host-BP-trace-hide-table-option-0-43.jpg
Reload tree

This option refreshes the displayed tree. Clicking on the circular arrow icon will force an immediate refresh. This provides a real-time view of the status of the nodes.

../../_images/2_041j_aggregator_realm_assets_modal-host-BP-trace-reload-option-0-36.jpg
Expand the tree

If any node is hidden, clicking on the icon with the arrows pointing to the ends will re-expand the tree view to show all of its nodes.

../../_images/2_041k_aggregator_realm_assets_modal-host-BP-trace-expand-option-0-36.jpg
Collapse tree

By clicking on the converging arrows icon, the entire tree will be hidden, displaying only the parent node corresponding to the BP Rule.

../../_images/2_041l_aggregator_realm_assets_modal-host-BP-trace-collapse-option-0-36.jpg
Centre tree

By scrolling with the mouse it is possible to manipulate the zoom in and out of the tree. The view can be centred immediately by clicking on the icon with two intersecting arrows.

Diagnostic

The set of actions that make up this view allow for an in-depth analysis of the current functional and operational status of a Network Host, in order to detect any anomalous situation that has occurred and to identify its nature and reason for failure.

The diagnostic function is synonymous with technical analysis, which is indispensable for the prevention of incidents that could compromise the stability of the monitored network infrastructure.

../../_images/2_087_aggregator_realm_assets_diagnostic-tab_0-57.jpg

Important

As a general rule, the following actions shall be performed and managed by the Import-Tool. In case the Host (object of diagnosis) is linked to a poller, then it is the poller that proceeds to execute the diagnostic task instead of the Import-Tool.

Note

The diagnostic function shall not be available in Business Processes views, as these processes can only be performed on physical machines (assets) and not on logical pools.

ICMP Probe

The ICMP Probe command is used to determine the status and connectivity of a Host. This protocol sends messages (ICMP Echos) to the Host to request a response and check if it has an IP connection, i.e. if there is communication at the network level.

In addition to determining this connectivity, the latency or time it takes for response messages to be received by the Host can be obtained.

The user must specify in the fields:

Number of packets: the total number of packets you want to drop to diagnose the status, speed and quality of the communication. There is a sending limit of 10 packets.

Timeout: time (measured in seconds) to wait for host response. Limited to a maximum of 20 seconds.

Package size (Bytes): size (measured in bytes) of the packet sent via ICMP. Limited to a maximum of 65507 bytes.

../../_images/2_088_aggregator_realm_assets_diagnostic-ICMP_0-50.jpg

Once the request is loaded and processed (button Run), the system will display the following result:

Set of statistical values resulting from the path of the set of packets, detailing the Round-Trip Average times, as well as the percentage of ICMP packets lost (Transmission Statistics).

A graph constructed from the recorded response times of each of the packages.

Activating the Raw View filter displays the raw output or response of the actual command launched and which WOCU-Monitoring captures in a table, graph or other formatted element for easy reading and understanding. By default, this component will be hidden, leaving more space for the rest of the data.

../../_images/2_089_aggregator_realm_assets_diagnostic-raw-view_0-48.jpg

Port Scan

As the name suggests, this process runs a port scan on a Host to locate externally exposed Services, PING sweeps, operating system detection and version detection.

../../_images/2_090_aggregator_realm_assets_diagnostic-port-scan_0-50.jpg

The user can add in the Ports field a separate port or combine with a range of them (separating each object by a comma). Next, the scan protocol to be executed must be selected. Possible options are:

  • TCP (Transmission Control Protocol): option ticked by default.

  • UDP (User Datagram Protocol): includes a 100 port limit. Higher requests will be declined.

  • TCP & UDP: combination of both protocols to optimally exploit each other’s strengths in data transmission.

Once the action is launched (button Run), the system will display the result through a tabular format, where for each identified port (column Port) the following information is recorded:

Column State: status of the port (open/closed).

Column Service: service that is running that port.

../../_images/2_090a_aggregator_realm_assets_diagnostic-port-scan-result_0-50.jpg

Note

The table will show a maximum of 25 ports. This is a limitation of the internal program executing the action.

Route Discover

This task allows to know the route that a packet takes to reach its destination, i.e. how it is routed to the machine where the Host under diagnosis is hosted. As a result, a list is obtained of the machines that have been routed (firewalls, balancer, network to network, etc.).

The user can specify the number of hops to the final machine in the Hops field.

../../_images/2_091_aggregator_realm_assets_diagnostic-route-discover_0-50.jpg

When the action is triggered (button Run) the system will display the following result:

Information about the Host (IP) end of the route, maximum hops or stations recorded and network packet size.

Through a tabular format, the following information is recorded for each recorded hop (column Hops):

Column IP: where the packet is located just at that hop.

Column Times: sending times for each of the three network packets sent (per hop or hop) to verify the consistency of the route.

Name Resolution

This function extracts machine identification information (address, email, manufacturer, etc.) by querying DNS servers.

../../_images/2_092_aggregator_realm_assets_diagnostic-name-resolution_0-50.jpg

Its configuration is very simple:

✓ Domain Name: selection of the Host Name or Display Name of the Host about which information is to be obtained. If both terms match, only one option will be displayed.

✓ Name Server: server object of the query. If the field is not filled, the responsibility passes to the Import-Tool.

Once the action is launched, the system will display the result in a tabular format:

Column Address: address for which information is obtained.

Column Time to live: time for which the DNS record must be kept or maintained.

Column Type: output type identifier. More information on the possible options here.

Column Value: information extracted from the query made.
