Nagios Plugin for PDU Power Consumption

[and1100]

All,

Is there a widely accepted or well recommended plugin for Nagios Core to monitor PDU (ping?) and power consumption? Would the brand of the PDU matter? I think we have APC units in these cabinets.

I've searched and found a few, but I was curious if anyone highly recommends a specific one and has seen success with one.

Thank you.

We can see if any other users chime in, though this plugin is quite highly rated:

Are you looking to monitor a brand other than APC as well?

They will also likely all encompass using SNMP to monitor.

This is great. I will try it as soon as I can. Thank you!

For now, we are only concerned with APC. How would I install this? I see it is just a script. Do I place it in any specific directory and recompile the plugins?

Thanks again!

The plugin would be added to the following directory assuming you are running core on centos/rhel:

Code: Select all

/usr/local/nagios/libexec/

No re-compile is needed to add new, already compiled plugins as most are just scripts.

Then, you would need to create a command definition for this plugin, and create a host for the IP address, and a service to use the plugin's command definition. Then of course you will need the SNMP version, community string, and to define the warning and critical thresholds. As far as creating a host/service/command definition this can all be found in the following document:

http://nagios.sourceforge.net/docs/3_0/ ... tions.html

The indexed links at the top should take you to the proper places.

Great, thanks! I will give this a try.

[slansing]

Great, let us know how it all works out for you!

Out of curiosity, do you have something similar to this for non-APC PDUs? This thing is awesome but we may need something for non-specific PDUs.

Thanks again for this great script!

I seem to be having an issue when implementing it into my cfg. When manually running it I get the following:

[root@vmnagios libexec]# ./check_apc_pdu_load -H 10.8.8.226 -w 35 -c 80
WARNING: 4.70 Amps of load PDU, please check.

Now on the Nagios GUI:


Current Status: OK (for 0d 0h 16m 40s)
Status Information: check_apc_pdu_load v1.0.0.1 (nagios-plugins 1.4.16)

\nNagios Plugin to check PDU APC Load
\nUsage: check_apc_pdu_load [-H hostname] [-c communauty] [-w warning] [-c critical]
-H Hostname
-C Communauty
-w (optional) warning threshold
-c (optional) critical threshold
\n

It seems to not be taking my values. Below is how my config is set up:


define service{
use generic-service
host_name pdu1-ca
service_description PDU LOAD
check_command check_apc_pdu_load!33%!80%!
notification_interval 24x7
contact_groups admins
}

and then in the commands.cfg I have the following defined:

define command{
command_name check_apc_pdu_load
command_line $USER1$/check_apc_pdu_load -H $HOSTADDRESS$ -c $ARG1$ -w $ARG2$
}

I've tried a few things but no luck to get this to report correctly in the GUI.

Thanks again.

try the command without the percentages:

Code: Select all

check_command check_apc_pdu_load!33!80!

[and1100]

Awesome, thank you! That worked. The only issue that it seems to be having is the GUI still reports the status as 'OK':

Host Service Status Last Check Duration Attempt Status Information

OK 05-17-2013 15:28:37 0d 0h 1m 43s 1/3 WARNING: 4.70 Amps of load PDU, please check.

As a result it will not send any alerting emails. Did I miss something?

Thank you again.
