[solved] graphing output from script w/ multi output fields

[billysneed]

Hello -

I have a python script that grabs the total number of ports and the active number of ports on a switch. It spits out the data formatted as "Total:<n> Active:<n>".

I'm only seeing the graphed info from the Total field, the Active field is always listed as 0, regardless of the value.

I turned up the logging and see the output correctly in the logfile:

cacti>grep "Host\[714\]" cacti.log | grep Active
12/21/2012 09:55:38 AM - CMDPHP: Poller[0] Host[714] DS[50199] CMD: /usr/bin/python /usr/share/cacti/scripts/getCiscoActivePorts.py <sanitizedIP>, output: Active:5 Total:35
12/21/2012 10:00:38 AM - CMDPHP: Poller[0] Host[714] DS[50199] CMD: /usr/bin/python /usr/share/cacti/scripts/getCiscoActivePorts.py <sanitizedIP>, output: Active:5 Total:35
12/21/2012 10:05:38 AM - CMDPHP: Poller[0] Host[714] DS[50199] CMD: /usr/bin/python /usr/share/cacti/scripts/getCiscoActivePorts.py <sanitizedIP>, output: Active:5 Total:35
12/21/2012 10:10:38 AM - CMDPHP: Poller[0] Host[714] DS[50199] CMD: /usr/bin/python /usr/share/cacti/scripts/getCiscoActivePorts.py <sanitizedIP>, output: Total:35 Active:5

I tried swapping the order of the output to see if that made a difference, but it didn't. Using 'rrdtool dump' (below) I see the .rrd file is listing a "U" value for the Active field, which I'm guessing is because something is invalid. I just can't figure out what it is that is invalid. The data template & graph template _seem_ to be just fine. Can anyone point me towards a source of the issue?

Thanks, I didn't know about that page in the wiki.

My issue ended up being the Maximum value being too low in the Data Source on the Data Template I created for the script. I set that to "U" for no maximum, and started graphing properly.

Thanks

And thanks for this GREAT tool.
