Performance Monitoring Infrastructure Request Metrics data output

In the WebSphere Application Server log file the trace record format is:

PMRM0003I: parent:ver=n,ip=n.n.n.n,time=nnnnnnnnnn,pid=nnnn,reqid=nnnnnn,event=nnnn 
- 
current:ver=n,ip=n.n.n.n,time=nnnnnnnnnn,pid=nnnn,reqid=nnnnnn,event=nnnn 
           type=TTT detail=some_detail_information elapsed=nnnn

[Version 5.0.2 and later]In the Web server plug-in log file the trace record format is:

PLUGIN:
parent:ver=n,ip=n.n.n.n,time=nnnnnnnnnn,pid=nnnn,reqid=nnnnnn,event=nnnn 
- current:ver=n,ip=n.n.n.n,time=nnnnnnnnnn,pid=nnnn,reqid=nnnnnn,event=nnnn 
           type=TTT detail=some_detail_information elapsed=nnnn bytesIn=nnnn 
           bytesOut=nnnn

The trace record format is composed of two correlators: a parent correlator and current correlator. The parent correlator represents the upstream request and the current correlator represents the current operation. If the parent and current correlators are the same, then the record represents an operation that occurred as it entered WebSphere Application Server.

To correlate trace records for a particular request, collect records with a message ID of PMRM0003I from the appropriate application server log files and the PLUGIN trace record from the Web server plug-in log file. Records are correlated by matching current correlators to parent correlators. The logical tree can be created by connecting the current correlators of parent trace records to the parent correlators of child records. This tree shows the progression of the request across the server cluster.

The parent correlator is denoted by the comma separating fields following the keyword "parent:". Likewise, the current correlator is denoted by the comma separating fields following "current:".

The fields of both parent and current correlators are as follows:

Following the parent and current correlators, is the metrics data for timed operation:

The type and detail fields are described as follows:
