Application Response Measurement (ARM)

Enables PMI Request Metrics to call an underlying ARM agent.

Before enabling ARM, install an appropriate ARM implementation on all WebSphere Application Server nodes. Verify with your ARM agent provider that Request Metrics is supported by the ARM agent implementation. ARM support is dependent on Request Metrics support.

Trace Level

Specifies how much trace data to accumulate for a given request.

Including one of the following:

NONE

No trace.

HOPS

Only accumulates on major process hops.

PERF_DEBUG

Reserved for enabling additional information over hops, but is not as performance intensive as DEBUG. Currently, provides the same level of tracing as HOPS.
