UPS Plugin

Nagios Nagios Plugins support
1

I would like to use the plugin that checks the UPS

Can it check UPS load, if it is on battery power or AC power and how much battery is remaining etc?

I need to monitor two large rack mounted APC UPS and if I could integrate it within Nagios that would be great!

Thanks,
WIll

It depends on the model and type of UPS you are using. Test the default check_ups plugin if it works for you. If it doesn’t (like in my case), you could use check_snmp with the OID that represents the variables you wish to get from UPS (load, battery status…). I suggest you to do some testing with snmpget command to get the proper output format for your check_snmp queries.

I am unsure if the UPS has a SNMP card but I shall check, Its a APC 5000.

Does the default check_ups use snmp to provide the UPS status/load information?

EDITED My reply was a bit unclear have edited to save confusion!

As far as I can see, the check_ups has these variables available:
-T, --temperature
Output of temperatures in Celsius
-v, --variable=STRING
Valid values for STRING are LINE, TEMP, BATTPCT or LOADPCT

But does it use SNMP to gather this information?

Don’t know. Haven’t found a word about snmp in plugin’s source files (although I’m not an expert in programming so my knowledge lacks in this case).

I wouldn’t bother so much about it. If your UPS is snmp compatibile, you just put check_snmp on OID you need and that’s it. The magic of Nagios is that it is customizable and expandable in many ways.

I have been all over the forums and search area and everything say to refer to the other…HELP!!

Does anyone have the syntax for the check_ups plugin?
I have 3 APC 2200R UPS with APC917 Network cards installed.

Any help would be appreciated.

Thanks

Maybe you’ve sorted this one out. I have APC Smart-UPS RT 6000 and I found a syntax for it.

Hope this helps.
As you can see I use hostgroup_name, you can change that to host_name if you’re just monitoring one ups. You can also change the critical and warning thresholds…
