HP Caliper User Guide Release 5.5 (5900-2351, August 2012)

• --memory-usage=all:30m
Causes process memory usage to be measured at the beginning, at the end, and every 30
minutes of the process's execution.
• --memory-usage=end
Causes process memory usage to be measured once: at the end of the process's execution.
• --memory-usage=
Causes process memory usage to be measured at the beginning, at the end, and every 1
second of the process's execution. (This is equivalent to --memory-usage all.)
• --memory-usage=15s
Causes no process memory usage measurement to be taken. Although it does specify a
sampling rate, it does not request that “timed” measurements be made. The system memory
measurement is still taken.
• --mem=e:5:b:t
Causes process memory usage to be measured at the beginning, at the end, and every 5
seconds of the process's execution.
Example Report Output
Memory usage data is only reported in text (-o) and CSV-formatted (--csv-file) reports.
Figure 28 (page 155) shows some example output for an SMP system.

How to Read the Reports
This section explains the information in the System Memory Configuration and Process Memory
Usage tables.
System Memory Configuration Table
This table is always present if the --memory-usage= option is used. It contains a snapshot of
total system memory at the start of the HP Caliper measurement run.
On a ccNUMA system, there are separate entries in the table for each of the logical domains. The
total of all domains is calculated and printed at the bottom of the table.
