This module makes the Apache HTTP Server version 2.0 aware of and a participant in ARM instrumentation flows. This module requires the services of an ARM agent library. http://www.opengroup.org/tech/management/arm/

The directive is used to control the name of the application as registered with the ARM4 agent.
The ARM4 standard defines agent functions, arm_block() and
arm_unblock() that can be called to record when a process is about
to perform an 'out-of-process' operation (e.g., network i/o) and
to record when that 'out-of-process' operation completes. Ideally,
Apache HTTP Server handlers that go "out-of-process" would be
instrumented to make use of the optional callbacks defined by
Setting "ArmInstrumentHandler on" causes this module to call
arm_block() and arm_unblock on behalf of a handler that is not
instrumented. There are a couple of problems with using this
directive as implemented. First,
