I’m new to the forum, and first time poster…
We have a problem the pmm-admin process for “mongdb:metrics” where it appends to files in /tmp which eventually fills up that filesystem. Can you change the location of the “mongodb_exporter” INFO/WARNING/ERROR files? Or run some sort of cleanup command from “pmm-admin” to get rid of old files?
(FYI, we just started using pmm and the graphs look great!)
