Nagios Support Forum

Hi,

When I logged into nagiosxi today I got the following: error: no output from backend.

We rebooted the server and got this message:

Message: A database connection error has been detected, we are attempting to repair the server, if the repair does not resolve the issue, please contact Nagios support.

Run the following from the CLI as root to attempt to repair the DB

/usr/local/nagiosxi/scripts/repair_databases.sh

Which I ran. It said it completed successfully but I still get the same error message with trying to access nagiosxi via the web gui.

I've included the output from running the repair_databases.sh with this post but we want to set up a support session.
The server is running 2014 R2.7.

Thanks!
Penny

p.s. I am able to login to the nagios core interface on the server.

Nagios XI also uses the Postgres database for login information, try running this command to restart the Postgres database, then check to see if you can login to the XI interface.
Login as root on the server and run the following.

Hi, Ok I tried that and it fails.

If this doesn't help, send us an email at [email protected]. This will open a new support ticket in our email ticketing system. We may need to do a remote in order to further troubleshoot this issue. Thank you!

I see this was resolved in a ticket, so I will be closing this thread now.
