Application Response Measurement

Application Response Measurement (ARM) is an open standard published by the Open Group for monitoring and diagnosing performance bottlenecks within complex enterprise applications that use loosely-coupled designs or service-oriented architectures. It includes an API for C and Java that allows timing information associated with each step in processing a transaction to be logged to a remote server for later analysis.
