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.
History
Version 1 of ARM was developed jointly by Tivoli Software and Hewlett Packard in 1996. Version 2 was developed by an industry partnership (the ARM Working Group) and became available in December 1997 as an open standard approved by the Open Group. As of 2007, ARM 4.0 version 2 is the latest version of the ARM standard.
