[Observium] Monitoring high number of host with Observium

Hi,

I am currently pondering if it would be a sensible idea to monitor about 3000 linux boxes with Observium.

Has anybody already tried Observium on that kind of number ? Any pitfall/recommendation ?

I don't currently planned to use the alerting feature, but I would like to get historical performance metrics on the machines.

I currently monitor about 150 switches for a total of about 10000 ports with an Observium VM that is running really really fine.

Could anyone recommend something about the sizing of the hardware needed and the disk space/performance required for that ?

The servers and Observium would be located in the same datacenter but do you think that polling that amount of host would cause issues ?  Best regards, Louis
