Hello @righter and @KartoffelSalat,
do any of you possibly use the dashlets “Host statistics” or “Service statistics”? Though you did state, that you do not see an “increase in CPU”*, perhaps you could still check out, if you are using them. If so, please to removing and re-adding them and report back. There will be a fix for this specific issue in the p10 → Fixed steadily rising CPU due to misconfiguration when cloning builtin dashboards
* It would be interesting to know what you mean exactly. Load or utilization? Additionally, I would like to point to a very interesting article in our official guide, when it comes to monitoring the CPU utilization also in this scenario. Because it might be the case, that only one process is causing a lot of trouble and blocking an entire core, without you noticing, because the 7 - 127 other cores don’t have anything to do and hence the (average) CPU utilization is very low. Check out at least Chapter 1 in the following article. It was an eye opener for me a couple of years ago: Best practices, tips & tricks
