Subtask #35914
Updated by Jason Dillaman over 5 years ago
Add a simple (empty to start) OSD perf metric query struct that can be optionally encoded into the Mgr->OSD MMgrConfigure message. The MgrClient should have a new method to register a callback to the OSD (see MgrClient::collect_pg_stats for example). This method would be invoked by MgrClient when a MMgrConfigure message is received and it will pass the optional query struct down to the OSD. The initial version will only support a client ops query, so the presence of the (empty) struct is enough to indicate that the query is enabled vs disabled.
