Hi,
the first suspect is not enough or too many concurrent pollers. The second one is crappy disk IO. And the third is crappy network.
I monitor around 300 different devices on a 8-core/8GB VM under kvm. Disks are on a ZFS server and served to the kvm boxes through NFSv4. CPU is usually at 14% and peaks (occur during discovery) are around 30%. The mysql server has been optimized for the workload and we’re using rrdcache.
There’s 8 concurrent pollers. Zero gaps in graphs.

Is there anyone who is monitoring 200 devices in Observium?
Because I am facing dropout and gap problem in graphs.
CPU and Physical Memory utilization also goes more than 80%. Server detail is here:-
Machine Type :- VM ( Guest OS) Physical Memory :- 12GB Swap Size :- 4GB No. Of CPU :- 8
Note:- We are monitoring 200 devices in Observium.
