check_apcupsd

Great script. I added a fix to show the serial. Here's the patch:

High. Nice script. Though I found a little bug.

When you clean leading zeros, you clean to many of them and a value of "0.0" becomes ".0" which is not detected by your script...

Here's a patch :

Below is the exercise,which I have done on Nagios Core 3.4.3.

Command1
touch /sbin/apcaccess
chmod +x /sbin/apcaccess

Command2
./check_apcupsd -h timeleft
Output: OK - Time Left: Minutes

Command3
/check_apcupsd -h ups1 bcharge
OK - Battery Charge: %

Means, it is not showing output in % properly. It seems that there is a need to modify the plugin again.

I just created a very small patch to add a few perfData information to make the script compatible with NagVis gadgets

How can I add ports to check_apcupsd plugin? I have apcupsd running ports 3551, 3552 and 3553 but Nagios only shows 3551.

thanks

We recently started monitoring all of our UPS's so this was extremely useful and the setup is fast and easy, BUT the only problem I have is if I have a host that has multiple UPS's and they're on different ports I am getting a null response. If i execute the same command from console i get a good response. Any suggestions? I have tried making separate services, putting them all on one host,tried adding the port option to the plugin, still nothing works.

Very handy plugin - ran into one minor problem in version 2.4 with the "status" command. check_apcupsd only looks at the first word in the STATUS: provided by apcaccess. Changing the check at line 188 from this:
VALUE=`$APCACCESS status $HOSTNAME:$PORT | grep -i ^$ARG | \
sed 's/.*: *\([A-Z]*\).*/\1/'`
to this:
VALUE=`$APCACCESS status $HOSTNAME:$PORT | grep -i ^$ARG | \
sed -e 's/^.*: *//' -e 's/ *$//'`

seemed to do the trick for me - now our brand new UPS can report "ONLINE NOBATT" and we'll notice!

Thanks!

An excellent plugin for APCUPSD but to expand it further it would be nice if it could provide performance data that can then be graphed by pnp4nagios and perhaps check a few more items reported on by apcaccess such as the mains voltage.

Great plugin! In the text file sample commands and services are included. Took about 15 minutes to set up and displays all UPS info nicely in nagios

Great work, thanks!
