I just saw it a few weeks ago when someone reached out to me with the same problem. Do you have 2 load services enabled for that host by any chance? Maybe you include the conf.d/ directory and therefore have 2 load services applied. One uses the default thresholds and the one with the custom thresholds.
Depends a bit on the setup but this sounds very suspicious.
Hi,
I found the problem. On the client “hostgroup = ep-middle” the was also a service file under /etc/icinga2/conf.d. I removed the file and now it OK. My question now: Why das the client use the local config???
Sorry, should have made clear that I assumed the include of the conf.d folder to be present on the clients, not on the master nodes. Glad you have resolved your nonetheless.
