Hi,

I am currently using Observium on 149 switches with a total of 10173 ports.
I can't say that anything is wrong with it, but the web interface seems a bit slow especially when you want to display pages with a lot of graphs.

Observium is currently running in a VM with 4 xeon E5-2650 cores and 3Gb of ram.
It's virtual disks are on a local raid5 composed of 10K SAS disks.

Observium report that it's VM use on average 25% of its CPUs with spikes at 40% when the web interface is heavily used.
The disk I/O doesn't go past 150 ops OUT and rare spikes at 50 IN.

Anyone could advise on what kind of hardware or software tweaking could help speed up the thing ?

Are they special requirements/tunnings for the rrd storage or the mysql database ?


Best regards,
Louis
