Cameron,
While you are editing that file, why not redirect the output from the poller to a file so you can see how long it is taking to poll all your devices? (It recommends when you need to increase the number of poller threads.)
*/5 * * * * root /opt/observium/poller-wrapper.py 1 >> /opt/observium/logs/poller-wrapper.log 2>&1

Hi Cameron, thanks for your help; I finally solved the problem ... the last line of the observium file in /etc/cron.d (*/5 * * * * root /opt/observium/poller-wrapper.py 1
/dev/null 2>&1) was not taken into account, so no polling was performed !
By just adding a new comment line after this last line, the poller command was taken in account; Linux newbie error, I guess ; shame on me ;) for newbies like me, the clue was to check the /var/log/cron file : no entry was found for the poller command that made me suspect something was wrong with this last line ...
thanks to all who helped

Yeah, it works if you can make it work.
If it doesn't work, just install it on Ubuntu. It's easier, and really is a condition of any of the development team helping with installation problems.

Works fine for me with CentOS 6.5.
Try going directly to one of the RRD graph image URLs (should be something like "/graph.php?...". Then add "&debug" to the end of the URL and see what you get in the debug output. -- Cameron Moore Manager of Systems & Networks Hardin-Simmons University, Technology Services Ph: (325) 670-1506 Fx: (325) 670-1570

just installed Observium CE 0.14.4.5229 on a CentOS 6.5 64bits in VMware Workstation 9 environment : no problem thanks to well done install procedure (http://www.observium.org/wiki/RHEL_Installation [1]);
added manually network devices via following commands with no errors : ./add_device.php xxx.xxx.xxx.xxx
./discovery.php -h all ./poller.php -h all
crontab updated as stated in install procedure ;
Everything seems OK during all these steps ;
When looking at the results via web interface, I can see all (CISCO here) devices with all their discovered characteristics (type/model, soft version, interfaces, % RAM, % CPU, thruput figures on interfaces, ...) but no graph is drawn at all (even after 4 hours) ;
by the way, the graphs legends are correclty, and the grids too, but no curve drawn;
when looking at /opt/observium/rrd directory, I can see a sub-dir created per each disvovered device and inside each of them, 1 RRD file created for each collected variable ;
(each device RRD subdir is about 40MB after a while, RRD files inside are not empty)
Any idea to investigate more about those empty graphs ?
thanks for any help
