Curious of Cacti Server's Load Average

flibbertigibbet · Post by **flibbertigibbet** » Mon Jan 04, 2010 4:11 pm

So I've been very curious to see if the way my cacti server's load average shows up is on a normal level. So I'm hoping to see some people's Yearly graph for their server's Load Average.

I'm getting around a 3, 4, 5 for my load avg. on the 1, 5, 15 minute averages.

Is this a normal range? Or too high, or abnormally low?

I know I have a good spike on mine which is because of something that got backed up. but my current avg's are there.

This depends on number of CPU's and sth like HT and stuff

Mine hovers around 1, all the time. Recent Quad-core Xeon, 8GB RAM, SAS 15K drives and Spine, with 6200 data sources.

I still get a noticable drop in interactivity every 5 minutes if I am working in vi or something on the server. It'd be nice if Cacti could spread it's polling load over the polling period, rather than a big burst.

But how will we know, which time each polling item takes to complete within poller interval's time?

The voices in my head were asking me that as soon as I pressed submit.

What's Up does this, but it's only really doing pings and connection tests, rather than more detailed data collection.

That's serious! Voices? You're not talking parseltongue, do you?

It's a bit off topic. But you may have had contention in your I/O subsystem. We would not be able to evaluate without seeing your log.

As for the other topic, you can naturally "slow" your poller by setting things like:

1) Threads
2) Processes
3) Script Servers
4) Max OID's

and very soon

5) Threads per host.

greatly look forward to having threads per host.
