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
