[Xymon] monitoring UPS

[John D. Alexander]

Hi Bill,

Thanks for the reply.  Your scripts are clever.  I may combine them into one script for ease of use.

I have individual pages for each ups (they are network connected SmartUPS 3000) and just ping tests right now.  It would be best if the UPS data were to go in each UPS page.  That seems to be a challenge - at least with my level of Xymon knowledge.

It would be useful to be able to initiate a custom test from hosts.cfg

Has anyone done something like this?

John Alexander

Hi John The Xymon NUT scripts page on our website sees a lot of activity. Glad to know that they are actively in use in the wild.  :)


The tests are reported back to the Xymon server as the machine that is running the test.

You can simply override the $MACHINE variable at the end of the script like so:


$BB $BBDISP "status $MACHINE.$COLUMN $COLOR `"$DATE"`

change to:

$BB $BBDISP "status ups-a.$COLUMN $COLOR `"$DATE"`

Or set MACHINE="ups-a" at the top of the script where the other variables are assigned.

I am also wondering if you can set an environment variable explicitly in the tasks.cfg file by doing something like so:

CMD MACHINE="ups-a"; export ups-a; $XYMONHOME/ext/xymon_nut_ups-status.sh

If this syntax works, then you could leave the scripts unmodified and have just one set for any number of UPSes being tested. Never tried that though.


Then, in the UPS sub page section of the hosts file:

subpage example-com_upses UPSes
title Example Dot Com UPSes
group-only ups-status|in-voltage|out-voltage|ups-load|bat-charge|bat-voltage
0.0.0.0 ups-a.example.com # CLIENT:ups-a noconn


Funny thing is, I always wanted to do exactly that same thing but never spent the time to look into it. Your questions prompted me to spend the 20 minutes to test this and verify that it does indeed also "work as advertised." :)

Maybe I will even find the time to update the website with this new information. :)

Hope this helps!
