WOCU-Monitoring Installation Guide

The purpose of this guide is to provide the necessary instructions for the correct installation of WOCU-Monitoring, through a few simple indications.

The deployment addressed in this document is an AIO (All-in-one) installation.

Requirements

WOCU-Monitoring can be installed on the following operating systems:

  • RedHat 9

  • RedHat 8

  • Debian 11

  • Debian 10 (deprecated in upcoming releases)

  • Ubuntu 20.04

  • Ubuntu 22.04 (in following versions)

In an AIO (All-in-one) deployment all WOCU-Monitoring components are installed on the same machine. A standard installation supports around 5000 monitored hosts with an average of 5 services per host.

The minimum requirements for this type of deployment are 16 GB RAM and 4 CPU cores, although it is recommended to use at least 32 GB RAM and 8 CPU cores.

Disk usage depends largely on the number of events generated by the tool, which in turn depends on the stability and availability of the monitored platform. It will also vary according to the retention times used to store these events. Therefore, it is difficult to make a real calculation of the disk space that will be used. As a general rule of thumb, such an installation with a retention of 3 months may require 128 GB, although 256 GB is recommended.

To monitor the base system on which WOCU-Monitoring is installed, the WOCU Health monitoring pack is available, which is useful for optimising hardware resources

Download installation package

Enterprise Version

The Enterprise version of WOCU-Monitoring is also available for download from the packages.wocu-monitoring.com repository, but in an authenticated form, so you will have to request credentials from the contact page.

Installation of the Enterprise version

WOCU-Monitoring can be installed with deb repositories (Debian/Ubuntu) or rpm repositories (RedHat).

Debian

There are two tracks:

  • Installation with packages

    It will be necessary to go to the directory where the package is saved, and then execute the following command:

    apt install -f ./[NOMBRE_DEL_PAQUETE].deb -y
    
  • Installation from repository

    The first thing is to set up authentication for the WOCU-Monitoring package repository.

    Note

    Remember to request your customer credentials from the contact <https://www.wocu-monitoring.com/contact/>`_ page and replace the ``<YOURCUSTOMERLOGIN> and <YOURCUSTOMERPASSWORD> variables with the values provided.

    All commands must be run on a console as root or with administrator privileges.

    bash -c ' cat >>  /etc/apt/auth.conf <<EOF
    machine download.wocu-monitoring.com
    login <YOURCUSTOMERLOGIN>
    password <YOURCUSTOMERPASSWORD>
    EOF'
    

    The repository is served by HTTPS, so if you do not have support for encrypted repositories, you must install the necessary apt support:

    apt update
    apt install apt-transport-https wget
    

    Next, you must add the package repository to the sources.list file on the machine and get the public key for it:

    • Debian 11

      echo "deb [arch=amd64] https://download.wocu-monitoring.com/repository/wocu-apt-internal-deb11 bullseye main" > /etc/apt/sources.list.d/wocu-monitoring.list
      wget -O - https://files.wocu-monitoring.com/wocu-monitoring.gpg.key | apt-key add -
      
    • Debian 10

      echo "deb [arch=amd64] https://download.wocu-monitoring.com/repository/wocu-apt-internal-deb10 buster main" > /etc/apt/sources.list.d/wocu-monitoring.list
      wget -O - https://files.wocu-monitoring.com/wocu-monitoring.gpg.key | apt-key add -
      

    Finally, the update of the local repository is required, together with the installation of the AIO package of WOCU-Monitoring:

    apt update
    apt install wocu
    

RedHat

There are two tracks:

  • Installation with packages

    It will be necessary to go to the directory where the package is saved, and then execute the following command:

    dnf install -y ./[NOMBRE_DEL_PAQUETE].rpm
    
  • Installation from repository

    The first thing is to set up authentication for the WOCU-Monitoring package repository.

    Note

    Remember to request your customer credentials from the contact <https://www.wocu-monitoring.com/contact/>`_ page and replace the ``<YOURCUSTOMERLOGIN> and <YOURCUSTOMERPASSWORD> variables with the values provided.

    All commands must be run on a console as root or with administrator privileges.

    bash -c ' cat >>  /etc/yum.repos.d/wocu-monitoring.repo <<EOF
    [wocu-monitoring]
    name=Wocu-Monitoring
    baseurl=https://[YOURCUSTOMERLOGIN]:[YOURCUSTOMERPASSWORD]@https://download.wocu-monitoring.com/repository/redhat8/
    enabled=1
    gpgcheck=1
    gpgkey=https://files.wocu-monitoring.com/wocu-monitoring.gpg.key
    EOF'
    

    After adding the new repository, update the repository metadata to ensure that your package manager recognizes the new repository:

    dnf makecache
    

    Next, you must add the package repository to the sources.list file on the machine and get the public key for it:

    echo "deb [arch=amd64] https://download.wocu-monitoring.com/repository/wocu-apt-internal-deb10 buster main" > /etc/apt/sources.list.d/wocu-monitoring.list
    wget -O - https://download.wocu-monitoring.com/files/wocu-monitoring.gpg.key | apt-key add -
    

    Finally, the update of the local repository is required, together with the installation of the AIO package of WOCU-Monitoring:

    dnf update
    dnf install wocu
    

Installation of additional modules

Note

Only applicable to Debian environments.

Additional modules can be installed depending on the customer’s needs and requirements.

Snmp-mibs-downloader

If the monitoring you are going to perform with WOCU-Monitoring is mainly based on SNMP requests, it is recommended to install this package, which includes the proprietary MIBS of most technologies available in the market.

The package is not installed by default in distributions, as it is not an Open Source licensed package. To install it, add support for downloading packages from the non-free repository:

  • Debian 11
    echo "deb http://deb.debian.org/debian bullseye main contrib non-free" >> /etc/apt/sources.list
    
  • Debian 10
    echo "deb http://deb.debian.org/debian buster main contrib non-free" >> /etc/apt/sources.list
    

Immediately install the snmp-mibs-downloader package:

apt update && apt install -y snmp-mibs-downloader

Initial configuration

The initial configuration of WOCU-Monitoring starts from a single file located at:

editor /etc/wocu/wocu.yml

It is not necessary to modify this file, as the default values are intended to work out-of-the-box. You can check the file with the default values in the following path:

editor /etc/wocu/default.yml

Attention

When modification is necessary, never make the change to the /etc/wocu/default.yml file (it is overwritten between updates). Instead, modify the /etc/wocu/wocu.yml file, adding new values (if necessary).

Once the final configuration has been obtained, run the following command to update the system with the modified values. This process may take This process can take up to 5 minutes.

wocu-ctl configure

Note

Additionally, you can obtain information about the current state of your processes by executing (in another terminal) the following command:

tail -f /tmp/minion.salt.log

As an example, this would be a possible response from the status command:

../../_images/7_073_example_response.png

Use the following command to launch WOCU-Monitoring processes:

wocu-ctl start

Next, check the status of the processes started through this command:

wocu-ctl status

Finally, it will be necessary to modify the /etc/hosts file by executingthe following command. Skip in case of upgrade.

echo -e "#WOCU \n<yourserverip> wocu\n" >> /etc/hosts

Access the WOCU-Monitoring interface at the following address from your browser:

https://<yourserverip>/aggregator

Installation of licenses

Operations

To configure the license for WOCU-Monitoring from version 57 onwards, it will first be necessary to obtain a valid license by contacting the Sales Team.

The license must be included in the following components of WOCU-Monitoring:

  • Aggregator

  • Import-tool

Which means that the following components will require a license:

  • AIO

  • agrgegator

  • monitoring

  • monitoring-aio

  • monitoring-visor

To install the license, you will have a compressed file (.zip) containing two files:

  • wocu.license

  • wocu_key.pub

  1. For the Aggreator component, the reference to these files are found in: /etc/wocu/default.yml.

    wocu-aggregator:
    
        license_file_path: /etc/wocu/wocu.license
        license_public_key_file_path: /etc/wocu/wocu.license.key.pub
    

    Next, it is necessary to copy the extracted files to the specified paths:

    File ``wocu.license`` move/copy to ``/ect/wocu/wocu.license``
    File ``wocu_key.pub`` move/copy to ``/etc/wocu/wocu.license.key.pub``
    
  2. For the Import-Tool component, the reference for those files is located in: /etc/wocu/default.yml.

    wocu-import-tool:
    
        license_public_key_file_path: /etc/wocu/wocu.license.key.pub
    

    Next, it is necessary to copy the extracted files to the specified paths:

    File ``wocu_key.pub`` move/copy to ``/etc/wocu/wocu.license.key.pub``
    

Having completed the above, set up and restart the components:

  • AIO and Monitoring-AIO

    wocu-ctl configure
    wocu-ctl restart wocu-aggregator
    wocu-ctl restart wocu-import-tool
    
  • aggregator and aggregator-api

    wocu-ctl configure
    wocu-ctl restart wocu-aggregator
    
  • monitoring and monitoring-visor

    wocu-ctl configure
    wocu-ctl restart wocu-import-tool
