I recently did some performance troubleshooting on a Windows Server where the Icinga2 Agents and its Plugins seems to crash the Server.
I found out that it does not matter which plugin or even powershell scripts where executed, all the execution was arround 30 sec, instead of normally 0,1 - 1 sec.
Then I realized that a antivirus software was in place, I disabled it for testing and it worked immediately fine.
Than I checked if there where other servers that hat longer execution time and yes, there are. With different antivirus scanning software in place. I was wondering because I never found this kind of problems yet.
What do you think about:
- Will it maybe make a difference if the service is running as system or as network service?
- Does the Icinga2 Agent dir always has to be in the exclusion list? I never did with nsclient either…
- Its not always. Its happens just sometimes and I cant really tell when it will happen.
Does anybody else ran into this kind of problems yet?
I tested with many different Windows Versions of Icinga2 (2.7.0 - 2.8.4)
Thank you for any hints on this!
