Measuring Memory Usage Concurrently with Other Measurements

You can request a measurement of your program's memory usage in addition to, and at the same time as, any other HP Caliper measurement.

To do this, use the --memory-usage=option. You can use this option with any measurement: --memory-usage=all[begin][:timed][:end][:PERIOD[smh]]

For example:

$ caliper cpu -o REPORT --memory-usage=all my_app

Use of this option causes two different sets of memory measurements to be taken, each reported in its own table in the report:

•Overall memory available (and currently in use and free) on the system

•Memory currently being consumed by the process(es) being measured by a particular HP Caliper run
