Its not obvious what the problem is.
The spikes seem to be evenly spaced, which is odd.
Its likely either a bug in the switch SNMP stack which is returning zero or referring to the 32bit counters, or a network congestion issue caused by a crown job.
Do all of the devices have the same software versions?

6 switches have one fw and 2 older fw one of them had no spikes.
I cant find any anomalies in network or logs which would cause such spikes. I was using 8 cronjobs for poller. I switched back to one now. No spikes so far. Could that have been the case?
I used cronjobs like mentioned in docs. */5 * * * * root /opt/observium/poller.php -i 8 -n 0 >> /dev/null 2>&1 */5 * * * * root /opt/observium/poller.php -i 8 -n 1 >> /dev/null 2>&1 */5 * * * * root /opt/observium/poller.php -i 8 -n 2 >> /dev/null 2>&1 */5 * * * * root /opt/observium/poller.php -i 8 -n 3 >> /dev/null 2>&1 */5 * * * * root /opt/observium/poller.php -i 8 -n 4 >> /dev/null 2>&1 */5 * * * * root /opt/observium/poller.php -i 8 -n 5 >> /dev/null 2>&1 */5 * * * * root /opt/observium/poller.php -i 8 -n 6 >> /dev/null 2>&1 */5 * * * * root /opt/observium/poller.php -i 8 -n 7 >> /dev/null 2>&1

Im having trouble graphing Avaya ERS5530 switches. Graphs generated have very wierd spikes of ~700 Gbps what is impossible. I have other switches drawing graphs just fine.

Has anyone got any idea what could case this?

Hei,
Looks ok now. It seemed my server could not handle 8 cronjobs. Strange tho, its vm with 2 core and 4GB ram.

Someone here posted a python wrapper for splitting jobs. You could see if it gives you better results. http://www.observium.org/wiki/Poller-wrapper.py
Yep its already running :)
