Sorry, 70 degrees, not 80. The load was fine. It's a machine to test things, but I kept using checkmk since I really liked it. All on one server, both monitor server and all clients.It's an old workstation - it runs around 60 degrees normally.
That said, it could very much be a config issue, I installed with the ansible role and left most everything as default. A very easy installation, and with ansible very easy to add new hosts to monitor as well. I'm up to 36 now, including some docker containers.
I switched back to 1 minute to test, and is warned for temp within 20 minutes, from 60 degrees to hovering around 70. Load from 2 to 3.5, threads from 1k to 1.2k all on the physical side. There's also a small change in IO that seems to be the checkmk server writing more to disk - the cpu on that host is only slighty.
I'm guessing that the temp going over is hardware related, a better fan might fix that issue.
I don't know if the load/thread increase is reasonable, but given the amount of checks done in the agent I'm perfectly OK with giving those resources to have all the data points checkmk collects available. It's helped a lot being able to go into details to see what's going on, checkmk makes that so easy.
Frogger, played a lot of that and had to stop myself before crossing roads for awhile after.
In my mind I was trying to optimize moving the same direction as the car and sneak in before the meeting car got there. I'm lucky to be alive.
