All,

Looking for a bit of help. We are getting the following warnings in all of our Mariadb Nodes error logs:

2021-06-24 14:04:20 149674 [Warning] Access denied for user 'mysqld_exporter'@'localhost' (using password: YES)
2021-06-24 14:04:21 149694 [Warning] Access denied for user 'mysqld_exporter'@'localhost' (using password: YES)
2021-06-24 14:04:22 149756 [Warning] Access denied for user 'mysqld_exporter'@'localhost' (using password: YES)
2021-06-24 14:04:23 149807 [Warning] Access denied for user 'mysqld_exporter'@'localhost' (using password: YES)
2021-06-24 14:04:24 149848 [Warning] Access denied for user 'mysqld_exporter'@'localhost' (using password: YES)

The error just keeps repeating and repeating.

Does anyone have any clue what part of the application is causing this and where we can update the password so that it quits failing? Or just disable the services causing this so that logs will calm down?

Thanks in advance

  Hi Casey O'Connor

  Did you enabled the agent-based dashboard via ClusterControl? I cannot assert that this can be from ClusterControl. Although we deploy Prometheus exporters such as mysqld_exporter. But I am wondering since we are deploying with the username of "cmonexporter" but not "mysqld_exporter". You can verify this by checking,

  ps axufww|grep mysqld_exporter

  Then see if this is running, then paste to us the result. Also can you also paste the result of the following if the above command is running,

  cat /proc/$(pidof mysqld_exporter)/environ

  Thank you.
