Hi,
Its not possible to get exactly 300 second polling because of the variable time it takes to poll things. Its also not required, because RRDtool will calculate correct rates for the poller period.
There shouldnt 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 its pretty rare.
Adam.

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:

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, )

What can I do to fix it?
