In the pegasus transfer output when integrity check is computed or checked against, we need to log the timing information on the stdout in a monitord parseable format.

@@@PEGASUS_MONITORING_PAYLOAD - START @@@
{
     "ts": 1437688574,
     "monitoring_event": "int.metric",
     "payload": [
       {
         "event":"check|compute",
         "file_type": "input|output",
         "count" : number of files of type checked or computed,
         "duration": total sum in seconds,
       }
      ]
}
@@@PEGASUS_MONITORING_PAYLOAD - END @@@

In the case, where we have in same invocation checks and computes, we will have multiple JSON elements in payload list
