Hi,
no, unfortunately not. I can't explain it with disk io. There are to less machines monitored and the vz/kvm host is not overloaded. The only thing i can suspect is, that observium is running as a vz container and this causes problems.
Before anybody moans, I know that firewalls and monitoring system should stand alone. But cost for power and administrational overhead would be to much for my intended monitoring.
From other monitoring software i know that this can happen if the collector needs to long for a polling cycle. But i must admit, that i read about "multi" polling in observium. I have to check whether this is active. Another solution would be, to set up a physical test server.
I did not checked in deep for logs and other stuff, because my main job actually is CEO of a business center and not it staff as a couple of years before. But i will do it when i have some free time.
At the moment i have " Total time for all devices: 59.73s" for polling. This result does not point to polling problems.
If i find the solution, i will not keep it for me and post it here.

PS: I run smokeping on the same machine with integration in observium. There are no gaps.
