Re: Monit load average monitoring

[Tino Hendricks]

Hi Leonhard,

I think this is not a monit specific question or at least can’t be easily answered.

As for the calculation for CPU utilization there are tons of explanations on the web, i.e.

https://community.tenable.com/s/article/What-is-CPU-Load-Average

And that makes clear that „good values“ are hard to give because it very much depends on your setup. 

Our main office server is very much bored around 0.05 since most services went to the cloud.

Wikimedia servers are used to +50% all the time.

I would start with aggressive ( = low) values and if you get too many false positives adjust them up.

Best,

Tino

Hi all,

        Just wanted to inquire about the load average monitoring option on Monit. From the manual, it states the following:

The load average is the number of processes in the system run queue per CPU core, averaged over the specified time period.

Could I get some clarity on how this system run queue works, and how does this compare to the other CPU utilization option? Additionally, what would be good values to configure for this load average value? 

Regards,

Leonard
