Problems

The Problems tab shows for a selected Realm, the active problems on the different elements monitored by WOCU (Hosts, Services and Business Processes). Likewise, it allows to obtain information about their status and to carry out the most common operation tasks.

From a single view and through two lists, it is possible to view all the Problems of a multitude of elements:

1. Hosts Problems List: collects Problems from Hosts and Business Process Hosts (BP Hosts).

2. Services Problems List: collects Service Problems and Business Process Services (BP Services).

../../_images/2_050_aggregator_realm_problems_tab_0-57.jpg

In the Problems tab itself, a number appears on a red background indicating the total number of Problems generated.

../../_images/2_050a_aggregator_realm_problems-detail-tab_0-36.jpg

If no alert is active, the tab will be disabled. WOCU will indicate this by changing the category text from blue to grey. Also the cursor will change to a prohibition sign when hovering over one of these categories without Problems.

Hosts Problems and Business Process Hosts (BP Hosts)

WOCU displays in the list of Hosts and BP Hosts, those elements whose status has changed from the normal operating state (UP) to any other operational state.

../../_images/2_052_aggregator_realm_problems-hosts-inventory_0-46.jpg

Attention

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

../../_images/2_082_aggregator_realm_assets_icons_0-46.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/47_03_icons_detail.png

More information can be found at: 1. Display technology identification icons on Assets, Problems and Events pages..

In order to make it easier for the user to read the data, the Type column contains the different icons that identify the type of Assets in the list. Additionally, by placing the cursor over the icons, a text will appear to remind the type of element (Host or BP Hosts). More information on the representation and identification of Assets can be found in Type field.

Important

Use the increasing or decreasing order of entries in the Type column to group and locate Assets of the same type.

../../_images/2_052a_aggregator_realm_problems-hosts-inventory-order-tool_0-36.jpg

Service Problems and Business Process Services (BP Services)

WOCU displays in the Services Problems and Business Process Services (BP Services) list those services whose status has changed from the normal operating state (OK) to any other operational state.

../../_images/2_051_aggregator_realm_problems-services-inventory_0-45.jpg

In order to make it easier for the user to read the data, the Type column contains the different icons that identify the type of Assets in the list. Additionally, by placing the cursor over the icons, a text will appear to remind the type of element (Services or BP Services). More information on the representation and identification of Assets can be found in Type field.

Important

Use the increasing or decreasing order of entries in the Type column to group and locate Assets of the same type.

Note

Enabling the Filter problem services if host down option in User Preferences may affect the data displayed in this pane.

Problems List Fields

The fields in the Problems listings are practically the same for both panels. In fact, these fields are also similar to the Host Inventory Fields.

The existing fields in each type of Asset are listed below:

Hosts and Business Process Hosts (BP Hosts).

From the Problems point of view, the two main fields to be considered in the first instance are the Status field, which indicates the severity of the event, and the Status Information field, which describes the circumstances of the event.

Actions of the Problem Listings

WOCU offers the option of applying a series of Actions on the Assets from the Problem listings. These are some of the fundamental tools in the operation and treatment of the Problems themselves.

To display the Actions menu, click on the icon in the Actions column in the row of the Asset/Problem you wish to edit. Then select the Action to be performed from the menu options.

Actions from the Hosts and BP Hosts Problem List

Actions from the Service and Business Process Services Problems List


../../_images/2_054_agregator_realm_problems-services-inventory-actions_0-36.jpg

The Actions applicable in the Problem listings vary slightly depending on the type of Asset: Host or Service.

Note

For a more detailed and extended explanation of the different Actions, see the detailed description in the Assets tab: Actions on inventoried hosts.

As a reminder, the available Actions are listed:

Problem Inventory Operational Options

WOCU has a series of very useful options that facilitate the treatment of the Problems of the monitored Assets. The joint use of filters and actions allows a more organised management of alerts in complex environments.

By default, all filtering options are hidden, leaving a larger and clearer space for viewing and reading data. Simply click on the arrow icon pointing to the ends and the available filters will be displayed.

../../_images/2_055b_agregator_realm_problems-inventory-show-hide-filters_0-58.png

Important

The joint use of available filters and actions allows for a more organised management of alerts.

The filters of the Problem listings are described below.

../../_images/2_055_agregator_realm_problems-inventory-filters_0-45.jpg

Massive Actions

This filter allows you to distinguish inventory assets by type, whether they are: Hosts, Business Process Hosts (BP Hosts), Services or Business Process Services (BP Services).

Las acciones masivas permite una gestión más organizada de randes cantidades de datos en entornos vastos y complejos.

La gestión de elementos se ejecuta a partir de los siguientes desplegables:

../../_images/2_097_aggregator_realm_assets_services-masive-actions_0-51.jpg

For this reason, it is very useful to be able to establish filters similar to those for problem processing, in order to have a clearer view of the status of the problems. For this purpose, WOCU offers the possibility to apply the following filters:

Selection of list items


Disabling this filter hides all Active Problems, i.e. those where the WOCU user has not taken any Action. By placing the cursor over the button you can find a reminder of the action that will apply the filter: click to hide all Active Problems.

  • Disabling this filter hides all Problems where the user has applied the Disable active checks action for that Asset. By placing the cursor over the button you can find a reminder of the action that will apply the filter: click to hide problems with “Checks Disabled”.

  • The Disabled checks and Acknowledged checks filters can be disabled by default, if the options are enabled in the User Preferences: Filter disabled checks and/or Filter acknowledged statuses.

  • Seleccionar el listado completo (Select All).

  • Seleccionar solo la página actual del listado (Select Current Page). Esta opción se puede emplear de forma concatenada, es decir, seleccionar varias páginas actuales y sumar los í­tems que contienen.

../../_images/2_097a_aggregator_realm_assets_services-masive-actions-selector_0-51.jpg

This functionality allows you to apply actions on several Problem records. By selecting at least two inventory records, this tab will display a set of actions that will be applied to the selected set of items.

To select one or more items from the list, simply click on one of the rows (highlighted in a darker colour) and it will be included in the joint selection.


To select multiple items, hold down the CTRL key while clicking on another of the items you wish to select. To deselect any of the items, simply click again and it will be removed from the selection.

../../_images/2_049g_aggregator_realm_assets_hosts-inventory-massive-actions_0-58.png

Applying mass actions allows for a more organised management of large numbers of problems in large and complex environments.

Note

The operational design of WOCU is oriented to perform in a simple and efficient way the tasks of monitoring and operation of Systems and Network elements: the usual workflow in this type of environment assumes that every Problem must be examined and treated by the operator or Administrator of the monitored elements. It is therefore always good practice to perform an acknowledgement (Ack) of the incidents handled, alternatively to disable the active checks (in certain circumstances), or to apply the scheduled downtime (in the case of scheduled maintenance or intervention). WOCU offers tools to keep your Problem view as clean and uncluttered as possible so that you can concentrate on an orderly handling of your Problems: it is advisable to establish good habits and incorporate a good workflow that includes a correct use of Problem Filters and Asset Actions.

Filtering by Duration

This filtering option modifies the display of Hosts and Services according to the time that the incident has been active, that is, the duration of the downtime or total failure. Remember that this information is recorded in the Duration field for each of the elements.

../../_images/2_049l_aggregator_realm_problems_inventory-duration-filter_0-40.jpg

This selector has multiple filtering options:

  • Duration < 5 minutes: Duration less than 5 min.

  • Duration < 10 minutes: Duration less than 10 min.

  • Duration < 15 minutes: Duration less than 15 min.

  • Duration < 30 minutes: Duration less than 30 min.

  • Duration < 1 hour: Duration less than 1 hour.

  • Duration < 2 hours: Duration less than 2 hours.

  • Duration < 8 hours: Duration less than 8 hours.

  • Duration < 1 day: Duration less than 1 day.

  • Duration > 5 min: Duration greater than 5 min.

  • Duration > 10 min: Duration greater than 10 min.

  • Duration > 15 min: Duration greater than 15 min.

  • Duration > 30 min: Duration greater than 30 min.

  • Duration > 1 hour: Duration greater than 1 hour.

  • Duration > 2 hours: Duration greater than 2 hours.

  • Duration > 8 hours: Duration greater than 8 hours.

  • Duration > 1 day: Duration greater than 1 day.

Flexible filtering allows you to respond to queries such as: display only Hosts that have been in a critical state for more than 2 hours.

Important

The settings made will be retained even if the user switches tabs.

Filtering Assets by Status Type

These filtering options modify the display of hosts and services according to their current status. This filtering makes it easy to choose items that are in a particular state.

For easy understanding and selection, the boxes use the same colours already associated with the different types of statuses. However, by placing the cursor over the box, a reminder of the status to be selected will be displayed. More information on statuses and associated colours can be found in: Statements of Assets in WOCU.

By clicking on a box, you can activate or deactivate this option. Note that once selected, the box marked with a tick (✓) will appear inside it.

../../_images/2_049j_aggregator_realm_assets_hosts-inventory-filter-status_0-58.png

Attention

The service filter by status type cannot be applied when the selected expansion/compression option is “Hide all services”. In this case no selection shall be applied.

Finally, once the filters have been configured, the changes must be saved by clicking on the blue “Filter” button, in order to reload the inventory with the new data request.

Impact

This option is enabled only for Hosts and Business Process Hosts (BP Hosts), not for Services. Applying this filter will only show the Problems of the Hosts whose degree of criticality or Impact is equal to or greater than the selected value. By default this option will be inactive and, therefore, all Problems will be displayed, whatever their Impact value:

../../_images/2_055c_agregator_realm_problems-inventory-impact-filters-off_0-36.jpg

The user will be able to select the Impact value he/she wishes to set as a filter. The selected option will be highlighted in red.

../../_images/2_055d_agregator_realm_problems-inventory-impact-filters-on_0-36.jpg

To remove the filter, simply click on the minus sign on the left.

Remember

The impact value is defined in the Import-Tool, specifically in the Business Impact field of the Hosts in Assets and Host Business Processes on Assets view. The impact is represented using a scale from 0 to 5, with 0 being the least vital and 5 being the most critical.

Impact Value (Impact) inherited in Business Processes

This variable is used to establish the importance that a Host or Business Process will have in the Realm, which will influence the normal operational flow, for example, in the treatment and notification of incidents to the operator.

By default, the default value is 2 for Business Processes and 0 for Hosts (scale of six values). Based on this situation, any Host that is part of the logical relationship that constitutes a Business Process, will inherit its impact value as long as it is greater than or equal to the one assigned to it as an individual element, i.e:

  • If the highest Impact is that of the Host, the one it has is maintained.

  • If the highest Impact is that of the Business Process, the Host inherits that value.

  • If the Host affects several Business Processes, it shall inherit the highest impact value among the above.

See example below:

Object

Impacto

h1

h2

none

h3

h4

BP A –> bp_rule!(h1 | h2) & (h3 | h4)

BP B –> bp_rule!(h4 | router7) & (web-a3sec | Local

For the above configuration, the system shall act as follows:

  • Host h1 will maintain its impact value since it is higher than that of the Business Process BP A of which it is a part.

  • The h2 Host, having no value, acquires the impact value of the Business Process BP A.

  • The Host h3, acquires the impact value of the Business Process BP A, since it is greater than its value as a particular entity.

  • In the case of the h4 host, two issues need to be observed:

    1. Su valor de impacto es menor que el de ambos Procesos de Negocio del que forma parte. En caso contrario conservaría el suyo propio.

    2. Hereda el valor del BP B, puesto que es mayor que BP A.

Filtros avanzados (Advanced Filters)

La aplicación ofrece otro sistema avanzado de filtrado sobre los elementos del inventario, siendo más sencillo escoger y visualizar ítems que se encuentran dentro de ciertas categorías o situaciones operacionales.

../../_images/2_055k_agregator_realm_problems-inventory-filter-advanced_0-57.jpg

Las opciones disponibles son:

  • BP Host: filtrado por tipo de activo, en concreto, por Procesos de Negocio de Dispositivos. Más información sobre la representación e identificación de Activos en Type field.

  • Disabled Checks: filtrado de activos en los que el usuario haya suspendido las tareas de monitorización activa que el sistema está efectuando, es decir, se haya aplicado la Disable active checks for services.

  • Acknowledged: filtrado de Alarmas que han sido reconocidas, es decir, en las que el usuario haya aplicado la acción Apply acknowledged to service para ese Activo.

  • Downtime: filtrado de Alarmas que están en Tiempo de Caída, es decir, en las que el usuario haya aplicado la acción Schedule downtime to service.

  • Active Problems: filtrado de Alarmas Activas. Se filtrarán aquellas incidencias en las que el usuario aún no ha realizado ninguna acción o tratamiento.

  • In Notification Period: filtrado de Alarmas con un periodo de notificación configurado. El listado mostrará únicamente las Alarmas que, en ese instante, se encuentran en el transcurso de su periodo de notificación.

  • Include softproblems: la tabla principal Host Problems muestra por defecto alarmas generadas tanto de tipo SOFT como HARD. Con este filtro se incluyen todas las entradas de alarmas de tipo SOFT del listado, y se exluyen las de tipo HARD.

La operativa en esta modal permite la concatenación de filtros, ofreciendo distintas combinaciones al operario para la visualización directa de datos de interés. Esto es posible debido a que cada filtro puede asumir 3 estados resumidos en la siguiente tabla. Basta con marcar seguidas veces la casilla de filtrado para pasar por los distintos estados indefinidos.

Estados indefinidos

The main table Host Problems displays by default generated problems of both SOFT and HARD types, sometimes triggering very long and informative listings.

To minimise this possible data saturation during the processing of active problems, there is the Exclude soft problems filter, which discriminates and extracts all SOFT type problem entries from the list, loading and displaying only HARD type problems.

../../_images/2_049u_aggregator_realm_assets_services-inventory-filter-button_0-55.jpg

Botón para el borrado de filtros aplicados (Clear Filter)

The operation is very simple, by ticking the leading box the listing will automatically load the table with the relevant items (Problems of type HARD).

../../_images/2_107_aggregator_realm_assets_services-inventory-clear_filter-button_0-55.jpg

Problem list export

Next to the search bar there are two options for downloading files in CSV and JSON format, for data processing and management in tools external to WOCU or for later use in the system itself.

../../_images/2_049k_aggregator_realm_assets_hosts-inventory-export-buttons_0-36.jpg

Clicking on one of the buttons starts the download of files in the format:

CSV (Comma Separated Value)

Simple format that separates columns by a separator (semicolon “;”) and rows by a line break.

JSON (JavaScript Object Notation)

Lightweight data interchange format capable of being read by any programming language and therefore being used to exchange information between different technologies.

By default the filename will be: problems_[realm name]_00h-00min_dd-mm-yyyy and the extension .csv or .json depending on the option chosen.

Important

If a filter is enabled, only the Problems corresponding to the filter criteria applied shall be included in the export file, i.e. the same filter applied on the screen shall be applied in the export.

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.

Botón Mostrar Dispositivos Seleccionados (Show Selected Hosts)

This list offers different specific filters to configure the display of Problems, which facilitates navigation and speeds up and narrows the search in lists that can be very extensive.
