Hosts Appearing Critical After Reload

This forum was archived to /woltlab and is now in read-only mode.
  • Hello, we have a server dedicated to running icinga2 with icinga2web client installed as a web GUI. In our ecosystem we monitor around 500 non-unique services distributed across around 100 hosts. Each time anyone reloads icinga after making edits to config files or updating templates many of services displayed in icinga2web will appear as Critical with their check status being in a state that usually appear as OK. What can we do correct this?

  • Can you share a screenshot as well as the output and the URLs provided to those plugins? Which versions of Icinga 2 and Icinga Web 2 are involved, anything in the logs?

    Please kindly follow the instructions in the FAQ (upper menu) too.

  • dnsmichi Sorry, I made this post just before the weekend and I'm not concerned enough with this issue to check on it during work hours. I just tried to replicate the issue and I think it's related to adding new host .conf files to conf.d and then reloading because I couldn't force the problem to come back yet. Scanning through logs and grepping for error doesn't produce anything unexpected.

    Wolfgang That might be it but it only seems to occur after I've added new host configuration files. It's difficult to force it to replicate because this instance is in production currently and people don't like seeing red but I'll look into what I can do.

  • dnsmichi I just got it to reoccur and it does only appear to happen after adding a new host .conf file to /conf.d/hosts.d/. It's not actually any of the services that appear critical but instead it's every host coming up as critical even though the ping check that's used as the default hostalive check returns PING OK.
