Hello. My name is Ilsoo Byun, I am writing to enquire about your commit(f5f2ced624809dfef997236a5fe352b221432fb7).

While I inspecting the ceph code, I found that slow operation warning is dropped from mimic in your commit. The description of the commit is as follows:

mgr/PGMap: drop REQUEST_{SLOW,STUCK} HEALTH_WARNs in mimic SLOW_OPS unifies both of them since mimic

Do you mind if you explain the reason?

i think the warning of REQUEST_SLOW and REQUEST_STUCK are covered by SLOW_OPS.

To explain our situation, we encounter slow op warning sometimes. And we regarded those warnings as H/W problems. So I want to know why this warning is dropped.

you can now instead use SLOW_OPS to identify potential hardware issues.
