Hello Billy,

Those are very good questions. Here is some information on those metrics.

Background threads: these threads complete tasks that are not related to individual requests made to the CPU.

Garbage collection CPU: this is the time the CPU spends in suspension while it cleans up threads and references to objects that are no longer in use.

Service request CPU: this is time the CPU spends completing requests made to it by services on the host.

Also, here are some Dynatrace blogs that go more in depth with those topics.
