Question Locating the process/user that's doing the mariadb query

[tkalfaoglu]

In the mariadb logs I see:

2022-01-31 13:24:23 864899 [Warning] Access denied for user ''@'localhost' (using password: NO)
2022-01-31 13:24:23 864901 [Warning] Access denied for user ''@'localhost' (using password: NO)
2022-01-31 13:24:23 864902 [Warning] Access denied for user ''@'localhost' (using password: NO)
2022-01-31 13:24:23 864903 [Warning] Access denied for user ''@'localhost' (using password: NO)
2022-01-31 13:24:23 864904 [Warning] Access denied for user ''@'localhost' (using password: NO)

I assume there is a website/process that's misconfigured.. but how to find which process is responsible?
Many thanks, -turgut
