Check your cacti log and ensure your poller is running properly and without errors.

I've just setup a brand new Ubuntu 12.10 box and tried installing Cacti from the Ubuntu repository, and I'm having issues as well.

It's creating the graphs, but everything is just showing up as 'nan'. I've tried working my way through the troubleshooting guides already, but I still haven't been able to figure out what the problem actually is.

I've probably set-up at least a dozen Cacti installs before this one, and I've never come across this particular problem before.

[DavidTomic]

OK ... so this is weird.

I left work yesterday, and all my graphs were just giving me 'NaN' (as above).

Get back this morning, and the graphs have started working over night - but only for about 5 hours - and now they've stopped again.

I've never come across this behaviour before?!?

I'm just about to start running through the Troubleshooting guide from scratch again, but does anybody else have any advice / suggestions which might help me out here?

So ... working my way through the Cacti debugging guide:

Check Cacti Log File

ALL looks okay. No errors / warnings to be seen, just lots of:

Please verify from corntab or from cacti.log, that the poller has indeed being run.
R.

[DavidTomic]

Yes, the poller was still being run fine.

I never did figure out what the problem actually was, but I just killed that install (it was just running as a VM) and setup a new one, configured everything exactly the same as the first one AFAIK, and it worked fine straight out of the box.

No idea ...

Hi,

I had the exact same issue, brand new install of Ubuntu 12.10 (apt-get install cacti) and the all the graphs were showing up with "nan".
I disabled apparmor (command "service apparmor stop" and "service apparmor teardown") and everything started working.

not sure exactly why apparmor was stopping Cacti, but happy my graphs are working now.
