It's likely that you have some system that is not finishing within the period of 5 minutes. Also you have only a single thread of the poller running. Try this:

*/10 * * * * root /opt/observium/poller-wrapper.py 4 >> /dev/null 2>&1

Replacing the "1" with "4", or you might try 2 and see where that gets you. Further to see which devices are taking a long time check the polling stats. Click on the globe in the menu then "Polling Information". Scroll down the list to see which of your devices is taking the longest.

Lastly, you may want to add a setting to you config.php to set the max-reps for snmpbulkwalk: $config['snmp']['max-rep'] = 5; // allow use of -Cr in snmpbulkwalk vastly increasing walk speed

Again, start low and move up. You might want to try manually polling the slow device from the cli and playing with that number to find your optimal setting.

I just went through the same issue and the combination of these things resolved my problems.

Hope that helps!

Hi Jerico,

You cannot increase the polling time. That's where the spaces come from. The rrd files are created with a 5 minute interval.

Regards,

Frederik

Hi Chip,

I already increased the poller-wrapper thread to 2 and added the snmp settings in config.php. I will be monitoring the graphs of my devices for 24hours for the improvement. Just to add when I use */5 or every 5minute interval i see great changes in cpu load of the system so I changed it to */10.

Thanks for your input

Jerico

To add if your system cant cope with polling every 5 mins then you need to upgrade your system! - check that the CPU load isn't due to IOwait though, if it is you are IO bound on performance and need to increase the speed of your disks (faster or SSD) rather than just increasing CPU/mem specs
