Ticket 262 ‐ Update Nagios Hostgroup to Include All Monitored Servers (Part 1 ‐ check_disk, check_users and check_load) - SupaHotBall/OE2-Group-D GitHub Wiki

Task

Updated the remote-disks Nagios hostgroup to include all relevant client servers (db-d, apps-d, backup-d) in order to ensure consistent NRPE-based service monitoring across the infrastructure.

Steps Taken

Edited the nagios::config manifest in config.pp to update the remote-disks hostgroup members line from

"db-d"

to

"db-d,apps-d,backup-d"

Ensure that the service groups are defined with the same format as previously defined service groups

}

Ensure that the file is saved and then run sudo puppet agent --test in the mgmt server

Once the configuration has been applied, restart the nagios4 service on the mgmt server to view the disk checks on the website.
