pmm-agent doesn't send slowlog until refreshing slowlog log file

Percona Monitoring and Management (PMM) PMM 2.x

Installing the pmm2 client with a system where Mysqld is already running. I’ve run into an issue where pmm-agent gets configured right but wont start sending slowlog info until I first

cp /dev/null /var/log/slowlog.log
service mysqld restart
service pmm-agent restartNot sure why this is but it’s a pain in the butt. Anyway to just have pmm-agent read the file that’s already there?

The answer was to flush logs
