To configure the right resources, we recommend checking the following graphs:

  • PDF report with graphs of
    • Cpu
    • Memory
    • OMD <SITENAME> Performance
    • activate the "Core statistics" snapin
    • Check_MKĀ 
    • Disk I/O Summary
  • The local structure
    • find -L ~/local > local.txt (as site user)



Info

Let's give you some example:


Info

With this snapin you will be able to check the load of the fetcher and helper. At 70% we recommend increasing these values in the global settings. While you're increasing these values the CPU load and Memory consumption will grow.


That's why also recommend checking these graphs:

Info

You will find here more information about the fetcher and checker architecture:

Note

One information about the Checker: The checkers shouldn't be higher than your cpu core count!


...

  • Maximum concurrent active checks
    • increase the helper for the active checks
  • Maximum concurrent Checkmk fetchers
    • increase the helper for the Checkmk fetchers
  • Maximum concurrent Checkmk checkers
    • increase the helper for the Checkmk checkers
  • Maximum concurrent Livestatus connections
Note

In a distributed monitoring setup it may be useful to have different values for the remote sites. You will find the guidance on how to do that here!
