Clear Linux log alert

I got a critical alert from a Linux agent and after I fixed the problem I went to checkmk to clear the log so the alert will go away. To my surprise, for the Linux agent there is no Open Log > Clear option like for the Windows one.
I tried by acknowledging the problem but the alert is still there after 24 hours.

How can I make the alert go away?


Could you maybe provide a screenshot from the linux service overview?

Here you go Friedrich

This is not a logwatch check but the queue check for nullmailer.
You need to clean the failed queue on the host itself for this service check to become green again.

Thanks a lot. Had no idea about this

Once I deleted all the files from /var/spool/nullmailer/failed the alert went away

Much appreciate it.
