Hi Adam
Well, it's happening then. Also set up Cacti to poll same interface to compare:
Observium:
Cacti:
As you can see, not so evident 'saw' in Cacti.
Moving observium to another server ( 24 cores, 8 gb RAM ) slightly improve it, but not enough to make curve 'smooth'. Could be any performance tunning ( I tried wrappers and threads variables )

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.
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:
/37554|1603201212|267|1785377894|1068531295|386467237639270|41301474049631|87Mbps|22.7Mbps|v2c 37554|1603201534|322|2182521058|2288947079|386489109618914|41306989432711|67.9Mbps|17.1Mbps|v2c 37554|1603201811|277|2993214954|3745224137|386511395149290|41312740677065|80.4Mbps|20.7Mbps|v2c 37554|1603202130|319|2034988746|794409408|386536206726858|41318379796928|77.7Mbps|17.6Mbps|v2c 37554|1603202410|280|215877678|2105208367|386560157419566|41323985563183|85.5Mbps|20Mbps|v2c 37554|1603202737|327|2876073363|3906420769|386584292451731|41330081742881|73.8Mbps|18.6Mbps|v2c 37554|1603203010|273|816113491|1430194856|386608002295635|41336195451560|86.8Mbps|22.3Mbps|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?
