             Summary: Capture time budgeting information
                 Key: ISPN-3193
                 URL: https://issues.jboss.org/browse/ISPN-3193
             Project: Infinispan
          Issue Type: Feature Request
          Components: Core API
    Affects Versions: 5.3.0.Final
            Reporter: Manik Surtani
            Assignee: Mircea Markus
             Fix For: 6.0.0.Alpha1, 6.0.0.Final


Should be most recent timing for each major subsystem for each type of call.  E.g.,

PUT: 10ms (locking), 10ms (datacontainer), 20ms (RPC), 30ms (CacheStore).
GET: 0ms (locking), 5ms (datacontainer), 0ms (RPC), 10ms (CacheStore).

etc.

Could be implemented as a simple ringbuffer, in a specific component (TimeBudgetMonitor?) just storing the most recent N calls and that's it.  Cheap to capture, cheap to store.

This data could then be made available via a JMX operation on TimeBudgetMonitor.  This is extremely valuable for tuning and debugging perf issues.
