Thanks Adam, that mostly did the trick. Dropped all the mibs, ran svn, and it didn't work out of the gate. Ran discovery on all devices again and we're back in business. Thanks for your help!

Thanks Adam, yes, that was a wild goose chase. I did not run "./poller.php -h <hostname> -m ports -d" that command with su. I ran it again with sudo and the test seemed to work fine. Still have the root issue of error drawing graph and none of the ports being visible at all. On all devices. Device details like ping response, process, etc work, but none of the port info on switches, firewalls, routers, or servers works.

Did you generate the output from the first email as not-root?


I think it wants someone to chase it! :D

Adam, I'm not sure it can't write the rrd's, I think it can't read them, but that' just based on the two log outputs I provided before. 

Tom, I don't think the FS is mounted read only but I'm not sure how to check that. I can sudo nano a new file into the /opt/observium folder without issue.

The debug log...

File system isn't mounted read only per chance?

Well what makes you think they can't write to the rrds? :>

Looks like root to me...

It seems that someone has modified your cron jobs to no longer be run as root, since your rrds were created by root and svn has no ability to change them.

You need to work out where the poller is run from. It should be /etc/cron.d/observium

Yes, svn update has always been run as su.

/opt/observium/rrd is owned by www-data, not root unlike the other folders in the main directory. However, digging into the directory, all of the folders inside for each host are all owned by root.

Are you running your poller observium poller as a non-root user?

Did you svn up as root?

The contents of the rrd directory, and anything else written to by the poller, should be owned by the user who runs the poller.

Recently upgraded from 69xx to 72xx after we renewed our license and it broke all of our RRD's, resulting in the "Error Drawing Graph" issue. 

Running this "./poller.php -h <hostname> -m ports -d" gives me two noticeable, but unobjectionable to me things:
SNMP_STATUS[TRUE]
 o Device status        Device is reachable by PING (8.28ms) and SNMP (81.63ms)
RRD CMD[update /opt/observium/rrd/hostname/status.rrd N:1]
RRD RUNTIME[0.0012s]
RRD STDOUT[ERROR: opening '/opt/observium/rrd/hostname/status.rrd': Permission denied]
RRD_STATUS[FALSE]
and this at the end of the results:
Log file '/opt/observium/logs/observium.log' is not writable, check file permissions.
So clearly some type of permission issue but not sure what happened during the upgrade that would have caused this. Any thoughts on what chmod's need to be set on the directories or what else could have went haywire?
