Problem with MySQL

Hi,

I’ve encountered a critical error in Nagios 1.2. I’m using Nagios to monitor MySQL server, but however Nagios gives me a critical error stating –

Access denied for user: ‘nagios@localhost’ (Using password: YES)

I’ve tried following the steps as described in arthur.ath.cx/doc/nagios-mysql/README.mysql, but I still can’t seem to fix it. Any advice will be greatly appreciated.

:slight_smile:

Do you have any checks at all currently working in nagios?
Is the MySQL server on the same box as the nagios server?
Is the MySQL server serving anything correctly?

Go to the server that is running MySQL and try logging into the mysql server using the user nagios.
It looks like you didn’t supply the pluggin a password to use.
