Nagios Support Forum

Latest VMware image. Apparently I grew the config too large for the Nagios XI web config to handle? It's getting stuck at Waiting for configuration verification. If I manually run a verify there are 184 warnings but no errors. What I'm trying to apply thru the web interface should fix the warnings. Any troubleshooting steps?

Update: When I try to stop the monitoring engine through the web interface, I receive the following error: "Please Wait. Your request was not processed in a timely manner. It may still execute, as the server may be temporarily busy." ps check shows it's still running.

Are you experiencing this problem after a recent upgrade? Another user reported a similar issue after upgraded and reported that restarting the Nagios server solved the problem. I'd try that and see if that fixes it.

No upgrade, this is the latest VMware image of Nagios XI. The problem began after the import of some config files, but I unchecked "Active" on the changes and it did not fix the issue. The strange thing is that although the "waiting for configuration verification" never ends (......'s fill the screen and it never times out), if I then go to Configuration snapshots there's an entry for when I kicked off the apply that says Config Ok. So I assume Nagios is running fine on my new config, but something got messed up with the return to the verify command? It's not tied to IP's / network config somehow is it? I also recently added a second NIC to the system, but it hasn't affected anything else in the XI web app.

I'd try using the "Write Config Tool" to manually write out the files, then verify the config, and attempt to restart Nagios that way.

I assume that works, it doesn't come back with any errors. But afterwards the Apply Configuration page still has the same issue.

Do you have any files in your /usr/local/nagios/etc/import directory? The Apply Configuration does all of the steps of the Write Config Tool, the only difference is that it imports any files in that directory created by configuration wizards.

The script /usr/local/nagiosxi/scripts/reconfigure_nagios.sh runs through all of the steps for "Apply Configuration" on the command-line. You could also try running that script and see if you get any notable error output.

Interesting...it uses wget to localhost, and I had changed httpd.conf to only bind to a specific IP, so the wget was getting connection refused. Fixed it by changing it back to "Listen 80."

Aaah, that's a good gotcha to remember.
