I see in the documentation that one should closely monitor Solr, but it doesn’t give any hints or clues on how to do this. I’ve begun to monitor Pressure Stall Information (PSI), a feature of newer Linux kernels, but I’m not sure if that would be enough.
I’ve looked at the Solr documentation, and they mention monitoring as well without specifying exactly how to monitor Solr. It seems monitoring is supposed to already be understood by the system administrator, and I don’t see clues on how to set this monitoring up.
I’m not having any problems with Solr right now, I’m still planning my initial deployment of mailcow-dockerized. I was rereading the installation and setup guide, and this monitoring aspect of Solr caught my attention.
