strange spikes

[depe]

Hi
I am using cacti 0.87b and spine under debian lenny.

All running fine so far, until some months ago whe I start to see some cuts in the graphs.
I setup the Cacti Poller statistics and seeing that every 10 min (sometimes 5, sometimes 40) show high latency spikes.

The cacti is runing in a VM under xen, I changed to a empty host, and base time are better, but still have the spikes.

You can see the spikes here.



Anyone has any tip or recomendation ?

I Have like 1.9k host, 952 host per process, 19.19k data sources and 13.89k RRDs.

Thanks and regards.

How many CPUs are allocated? Surely you're using spine? Pay attention to script timeouts when running scripts

Reinhard, thanks for answer, I have 2 CPU enabled
xm top show 190% when getting data.

100% sure spine is running.

Then run 4 processes and 10-15 threads.
Again, watch out for scripts timing out
