Top processes / CPU usage

[gera83 (Gerardo)]

Hi there.
A short question this time.

Once i see a Windows server/Linux server with 100% CPU usage, i would like to see the top 3 processes with high cpu usage.

Well, i do a cmk -d Server and i get this:

ETC

Can you confirm any of those is “cpu usage” ? or is all about memory, threads, kerneltime, etc?
If not… how can i get the top ten processes with check_mk? do i have to create a local check? please, tell me that i dont need to do that. We have 3000 servers.

Thanks!!

With the buildin checks, the closest you can get is this:

Create a rule of type “Process discovery”. Select “Match all processes”, and “Enable per-process details in long output”. Give the check a name (here: “ALL”).

Then rediscover all affected hosts. You will get a “Process ALL” check. In the long output, there will appear a list of all running processes with Memory and CPU usage:

However, this presentation does not sort the process list by CPU usage, nor selects the top consumers.

For a check that fits your needs better, I think the easiest way is to write a local check that creates the desired output. It might also possible to write a server-side checkplugin which has access to the “ps” section of the agent output.

Hi guys,

Take a look at this thread: Although for Linux, there are good ideas for an alternative approach to get e.g. the five most CPU intensive processes.
