The ido-mysql rate is roughly the number of SQL queries executed by Icinga. However, as you’re running a quite old version, you have to take that number with a grain of salt as this metric was improved recently and what you’re seeing is the rate at which the worker is executing jobs (and not each job executes exactly one query).

The relay queue shows how many messages where processed when communicating with other Icinga 2 nodes using its cluster feature.
