Hi,

It’s not possible to get exactly 300 second polling because of the variable time it takes to poll things. It’s also not required, because RRDtool will calculate correct rates for the poller period.

There shouldn’t be spikes outside the event that devices return an incorrect counter and then revert back to the correct counter. This happens on a few devices, but it’s pretty rare.

Subject: [Observium] Polling not periodical

Hello

We are using latest Observium 20.9.10749 (stable), paid edition
Noted that in some graphs, kind of spikes.
Debugging shows that the polling interval is not every 300 seconds:

37554|1603201212|267|1785377894|1068531295|386467237639270|41301474049631|87Mbps|22.7Mbps|v2c

So, the graphs is with spikes, because not similar period taken.

Obviously, each 5 minutes, CPU raises to 75% ( Xeon 16 Cores, 8 Gb RAM, )

[2020/10/20 11:21:04 -0300] observium-wrapper(611935): /opt/observium/observium-wrapper: processed 160 devices in 62.68 seconds with 32 threads, load average (5min) 8.45

What can I do to fix it?

Regards
