We don't have sudo access yet for MariaDB to stop / start etc... I'm going to work on that. Only two of our servers use Maria atm. I have a feeling the last security patches ran over something mucking us up...

Hi, @JakeHatMacys. Are you able to sign in with the following command? Also, please run the following command and show me the output:

I get an access denied error, should that work given we're running mariadb?

@JakeHatMacys, Yes, this command should work on the mariadb as well.

I have a feeling the last security patches ran over something mucking us up...

Most likely the database password was overridden during the patching, and now Nagios can not access it.

If I can get someone with root to set the password back to the default on mariadb what would that command look like??? can DM me it if you like....

@JakeHatMacys, You can try following this tutorial:

Try to backup your system before doing this though. If you run it on a VM make a system snapshot.
