Below are the logs you have requested while attempting to add comment and acknowledge an event. I was not able to check the mysql logs, we use remote Mysql server and the DBA, only log ERRORs

Did you already try if rebooting the server helps? I once had a similar problem and havent seen it again since I rebooted.

Stop services in this order:

Code: Select all

service ndo2db stop
service mysqld stop
service postgresql stop
service nagios stop
service gearmand stop


shutdown -r now

Grtz

Thanks @willemdh. Let us know if this works for you, OP!

Did the restart of the server and attempted to acknowledge and comment a service as nagiosadmin, with no success.

Posted: **Tue Feb 16, 2016 6:09 pm**

Can you login to the Core interface as the nagiosadmin and see if you can acknowledge a message of add a comment and see if that works?
To access the core interface, use this URL. Replace xxx.xxx.xxx.xxx with IP address.
http://xxx.xxx.xxx.xxx/nagios/

Can you login as root on the server, run the following and post the output?

Code: Select all

ls -l /usr/local/nagios/var/
ls -l /usr/local/nagios/var/rw

Thanks

http://xxx.xxx.xxx.xxx/nagios/

Thank you for the URL, that pointed out that nagios service was not running. After starting it up, the comments and acknowledgement worked.

This issue can be closed.

Ah - nice to see this resolved.

Closing this one out now, but feel free to open a new one if you need any assistance in the future.
