ARM Vs Java Profiling [message #127066]

Experts,

Execution Statistics are generated when I profile a java application
with both ARM Analysis and Java profiling. The base times and cumulative
times are slightly different in both cases. If Java profiling can
measure the time taken for a method to execute, then why do we need ARM
profiling? Is there an advantage of using ARM over using Java profiling.
For java code which is the best?

Regards,
Krishna

ARM has a couple of capabilities that profiling does not have: you can
use ARM to track method invocations across multiple processes (which can
be on multiple machines), assuming that a correlator is passed (done
automatically for HTTP and SOAP); also, you can use the ARM API to
report response times to production monitoring products from IBM and HP
(not sure what other companies have products that support ARM).
