be a multiple of the requested sample period
(--memory-usage=nnn), which defaults to 1 second. “Gaps”
in the time sequence of snapshots indicate a stretch of time
where the process's memory usage did not change.
Domain Id System identification number of the logical domain.
On ccNUMA systems, cell local memory domains are numbered
starting at 1, and the interleaved memory domain Id is –1.
On SMP systems, the only domain is numbered 0.
Shared Pages Number of shared resident memory pages currently in use by
this process. This is typically executable code for the program,
shared libraries, and mmap'd (shared) regions. These are pages
that could be shared with another process but are not necessarily
currently being shared.
Private Pages Number of private resident memory pages currently in use by
this process. These are typically static data and dynamic
(malloc'd heap) regions. These memory pages cannot be shared
with other processes.
Weighted Pages Number of resident pages for this process, weighted by the
number of processes actually sharing each page. Private pages
count as one page and shared pages count as the page divided
by the number of processes sharing that page. Therefore, it will
be at least as large as the number of private pages but less than
or equal to the total number of pages. It indicates the “load”
that this process is putting on system memory.
Total Pages Total number of resident pages that are currently allocated to
this process. It is the total of Shared Pages and Private Pages.
Measuring System Usage Concurrently with Other Measurements
You can request a measurement of your program's system usage in addition to, and at
the same time as, any other HP Caliper measurement.
To do this, use the --system-usage= option. You can use this option with any
measurement:
--system-usage=[all][:runstatus][:cpu][:io][:syscalls]
For example:
$ caliper cpu -o REPORT --system-usage=all my_app
You can use this option to get four kinds of system measurement data:
