Today one of our hosts was accidentally updated with yum update. As a result, pmm-agent was updated to 2.10 (server is 2.9.1). I started seeing those errors in logs:
Is it a result of combination 2.10 agent with 2.9 server? Or this is a bug in 2.10 agent?
- Group replication metrics should be for MySQL 8.0
- MySQL 5.7 and older should not have an error in logs and it's expected do not have GR metrics
