Application Response Measurement
Request metrics information might be either saved to the log file for later retrieval and analysis, be sent to Application Response Measurement (ARM) agents, or 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.
We can choose our own ARM implementation providers to obtain the ARM implementation libraries. Follow the instruction from the ARM provider, and verify 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_ROOT/libIf the underlying ARM implementation is ARM 4.0, specify the ARM transaction factory class name. Otherwise, this spec is not required.
