Its support will come with XorMon NG 1.6.0 going to be released in Sep 2024


Implementation is agent less.
Data source is ovirt_engine_history database which is part of Data Warehouse on oVirt/RHV Virtualization Manager.
Tool accesses the ovirt_engine_history database remotely via its SQL API.
ovirt_engine_history database contains only historical performance data. There is only the admin account which we use.

OS Prerequisites

• Open network connection to the RedHat Virtualization Manager on port 5432
  
  
• Make sure you have installed perl modules: perl-DBI and perl-DBD-Pg on XorMon NG server
  Skip that on the Virtual Appliance
  

  # RedHat / Rocky Linux
  rpm -q perl-DBD-Pg
    perl-DBD-Pg-2.19.3-4.el7.x86_64
  
  # Debian / Ubuntu
  dpkg-query  -W libdbd-pg-perl
    libdbd-pg-perl	3.18.0-1.pgdg120+1
  

  Install them if they are missing under root user
  
  
  • Linux RedHat, CentOS

    yum install perl-DBD-Pg
    

  • Linux Debian, Ubuntu

    apt-get install libdbd-pg-perl
    

Database access

Each Virtualization Manager has its own randomly generated password for ovirt_engine_history database.
To get the database password, you have to connect to your RHV / oVirt engine via SSH and run this command:

# grep DWH_DB_PASSWORD /etc/ovirt-engine-dwh/ovirt-engine-dwhd.conf.d/10-setup-database.conf

DB username should be ovirt_engine_history by default, check it with this command:

# grep DWH_DB_USER /etc/ovirt-engine-dwh/ovirt-engine-dwhd.conf.d/10-setup-database.conf
  ovirt_engine_history

XorMon NG storage configuration

• Add oVrit / RHV / OLVM from the UI:
  XorMon NG UI ➡ Settings icon ➡ Device ➡ Server Virtualization ➡ RHV/oVirt ➡ New ➡
  
  
• Run "Test" for configured storage device, it must show "OK"
  
  
• Wait about 1 hour, then reload the web browser, you should see it in XorMon NG UI
