Nagios - Anyone know how to Setup Nagios Alerts to work with a Liebert GXT4 UPS

Please HELP!!

I have started installing Liebert (Vertiv) GXT4 Rack UPS systems. I need to get Nagios talking to the UPS unit. Nagios runs on a Linux. I can setup new APC UPS systems in Nagios with no problem, I think I need a Plugin for the Liebert GXT4 and I need to know how to set it up and what commands I can use for Nagios to report to us.
Example APC check command: snmp_ups_stat! -H $HOSTADDRESS$ -C public

Below is how it looks on the Nagios screen. It shows that the UPS is UP and Online but the commands for the services are not working, probably because I am using the same commands the APC UPS systems are setup with.

I need to get the commands for a Liebert UPS system and if needed, a plugin installed.


Any help would be appreciated!!!
