Adjust poller threads, check if unneeded modules are acitivated i.e. fdb-tables, use rrdcache, optimize mysql server. We are running Observium on a VM with 24 cores (40% used), 64gb ram (70% used) with 916 devices, 33k ports and poller is finishing still below 300 seconds 😉 Disable down devices if you have to many of them, they are blocking polling threads until timeout is reached.

Make sure you are using rrdcached as it greatly helps with the handling of the rrd files.

By failing I am referring to the classic gaps in graphs for all my devices. I am running on esxi with 16 cores @ 2.40GHz, 16G of ram, SSD SAS Raid and continue to have gaps. Most recently I have pushed sql to its own instance in hopes of working around potential IO issues but that didnt help. What I do see is that my ram use is very high, I am guessing from the discovery process twice a day. When my ram use is lower throughout the day, I have no gaps. I am monitoring 6000ports on 190 devices. Should I be using north of 16G of ram in my env? I am happy to add more but all my reading indicates that observium is not RAM intense. My last attempt will be to move the RRDs to a ram disk but my RRDs are almost 16G at this time which I am guessing is part of the problem. Maybe it is time to clean house. Any insight would be appreciated. db _______________________________________________ observium mailing list -- [email protected]<mailto:[email protected]> To unsubscribe send an email to [email protected]<mailto:[email protected]>
