Nagios XI Deadpool can't delete a server and services

[emartine]

We are getting a slew of emails from the deadpool setting that we created and are trying to figure out why we were getting so many notifications. Seems like the server that we asked to be deleted is still there. Any idea why?

Deleted Hosts
===
The following hosts were deleted from the monitoring configuration because they remained in a problem state longer than the stage 2 deadpool threshold.

What version of XI are you running? You can grab the version from the bottom left hand side of the web interface.

Additionally, did you follow this guide?

https://assets.nagios.com/downloads/nag ... ios-XI.pdf

Please PM me a copy of your profile as well, you can download it from Admin > System Profile > Download Profile.

I want to make sure you don't have too many kernel message queues or duplicate nagios processes or something else from the logs.

Please send me your full /usr/local/nagiosxi/var/deadpool.log as well.

I will PM you the output.

So it looks like it's used in a host escalation and because of that it's being blocked from being deleted and would loop over and over like that. You can either remove fakeserver from the the fakeserver_lv1 host escalation and it should be deleted on the next deadpool go-round OR you can manually remove both OR you can put fakeserver in the exclude filter in your deadpool settings to keep it from logging all that info.

Is that in the documentation?

[tgriep]

The inability to remove a Host or Service because of a Dependent Relationship is the expected behavior for the Nagios System.
It keeps the system from creating a bad configuration from happening and causing the system from starting.

This link has some more details.

I just checked and it's not in there, I will recommend that that be added to the documentation and hopefully to the interface as well to avoid confusion since it's technically working the way it should.

[emartine]

The behavior it exhibited was to email every almost evey minute saying it was attempting to delete. Maybe a message should be sent out saying that it has an escalation? Just a thought.

I agree that's an issue and I'm surprised that it occurred, I'm looking at the code now to see what can be done.
