Activating the JARM Trace 

Use

Use this procedure to activate the trace for the JARM functionality. This is the Single Activity Trace (SAT) used to trace the data collected by JARM for single requests to a trace file. The SAT trace is switched on/off from the Distributed Statistics Service (see Activating the Single Activity Trace), but its data is written only if the tracing in JARM is activated.

Procedure

...

       1.      Choose Server → Services → Performance Tracing →Properties tab.

       2.      Select the jarm/tracemode/switch and modify its value.

Data recipients can get trace data only if the value is “on”.

       3.      Select the jarm/comp/trace/level and modify its value.

This property sets the general component trace level. If Single Activity Trace (SAT) is on, the default component level is specified by this parameter (same values possible as with jarm/comp/level property). If monitoring and tracing are done, the most detailed component level specified by jarm/comp/level and jarm/comp/trace/level properties is used. After the execution of components has started, the component level is fixed for the request. This avoids possible mismatching of start- and endComponent pairs in case the parameter changes. The components are treated only if their monitor level is lower or equal to the level of the request.

Three different levels are provided: 0, 1, 2. The default value is 1.
