I see the same issue. I’m running the OVA and MySQL community server on the the client. All the pmm services are running properly on both boxes, as far as I can tell. I removed the linux:metric service, and then purged. I don’t see a log file in /var/log for the linux:metrics service.
sudo pmm-admin --verbose purge linux:metrics
