Nagios Support Forum

Hi there,

My server ran out of disk space and ceased nagios from running. After freeing up some space and running /usr/local/nagiosxi/scripts/repair_databases.sh, everything seems to be back to normal, i.e all System Component statuses are green.
However, the Monitoring Process Engine state is red only under Monitoring Engine Status. Now Monitoring Engine Check Statistics are all 0 as if no checks are being run. When I however check Nagios Core, it seems to be working perfectly. Its almost as if Nagios XI is "frozen".
Any support will be really appreciated. Thanks.

Using Nagios XI 5.8.7

Thanks for reaching out @fowfo,

Do this happen even after restarting nagios, mysql, apache/httpd, and if relevant, php-fpm? Are there any errors in log files for those processes that might indicate some sort of bug or error?

Restart the server.
systemctl restart nagios
Read the output.

Check the output of journalctl -xeu (service name), for each of the services mentioned by danderson.

Hello All,
I am facing this same issue. What is the command to restart the Nagios service?

To restart nagios you should be able to just run:
systemctl restart nagios

Thanks, sgardil!

The /usr/local/nagiosxi/scripts/repair_databases.sh script seems to allow the system to function normally for a few minutes. The system freezes again after 10 to 20 minutes.

We appear to be in a better state.

We had to run the manual backup script to resolve the freezing issue. It seems that the disk may have run out space during a backup.

Thanks for sharing the solution for your issues and yeah that would do it. When you ran the script manually did you run the database repair script beforehand and then immediately manually run the back up script?

Yes, we ran the

• repair_databases.sh

then ran the

• backup_xi.sh

.
