Hi Peter,

Do you have all the modules enabled?

When I set it to 64 threads the load goes up to 60 but it makes the cycle in 3 minutes.

I don’t see much network traffic and also not very much disk access.

What load is you system having?

Regards,

Frederik

Subject: Re: [Observium] poller performance

We are running poller-wrapper with 64 threads, and our 250 devices and 20000 ports is getting polled in about 2 minutes.

We are running this on SSD drives for performance.

Hi,

I'm having problems with the performance of the poller.
We have 200 switches and almost 16000 ports included and the poller is having trouble getting them checked in 5 minutes.
With 20 threads it's working with a load of 15. When I add more threads it takes longer to get the data from switches.
With less threads it also doesn't check all switches in 5 minutes.
I'm using new fast hardware.

I've implemented all the performance tuning tips on the observium site.
I also disabled the checking of fbd-table, arp-table and mac-accounting.
When I debug the poller the ports check takes the longest. About 90 % of the total time.
1 switch takes about 8 to 10 seconds now.

Is there a way to speed it up? Maybe I can extend the check cycle time to 10 minutes?
Distributed poller instances?
