Application Response Measurement
&nbfp;
Request metrics information might be either...
- Saved to the log file for later retrieval and analysis,
- Sent to ARM agents
- Both.
Request metrics provides response time for each of the major WAS components through ARM APIs.
ARM is an Open Group standard. Request metrics helps you to plug in an ARM agent to collect response time measurements.
WAS does not ship an ARM agent. However, it supports the use of agents adhering to ARM 4.0 and ARM 2.0 standards.
You can choose your own ARM implementation providers to obtain the ARM implementation libraries. Follow the instruction from the ARM provider, and ensure that the ARM API JAR files found in the ARM provider are on the class path so that the WAS can load the needed classes.
In the case of Tivoli Monitoring Transaction Performance, V5.3, copy...
- armjni.jar
- core_util.jar
...from the Tivoli Monitoring Transaction Performance directory...
TMTP_INSTALL_ROOT/lib...to...
app_server_root/libIf the underlying ARM implementation is ARM 4.0, specify the ARM transaction factory class name. Otherwise, this specification is not required.
