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?
