Monitoring Custom Directories in Linux

Thank you Andreas as usual. For being supportive. I will give this a try. I have a different question: Regarding the piggyback data in the server. How long does it take for CheckMk to remove the outdate entries from the server from this folder /omd/sites/ro/tmp/checkmk/piggyback/. Is it something that we can configure to run faster?

Thank you in advance
