Usage by Heat specifically? Or just in general?
heat-engine specifically.
We're limited by what is logged in the gate, so CPU usage by Heat is
definitely a non-starter. Picking a random gate run, the Heat memory use
comes from this file:
http://logs.openstack.org/27/445627/2/check-tripleo/gate-tripleo-ci-centos-7-ovb-nonha/9232979/logs/ps.txt.gz
which is generated by running `ps` at the end of the test.
We also have this file (including historical data) from dstat:
http://logs.openstack.org/27/445627/2/check-tripleo/gate-tripleo-ci-centos-7-ovb-nonha/9232979/logs/dstat.txt.gz
so there is _some_ data there, it's mostly a question of how to process it
down to something we can plot against time. My first guess would be to do a
box-and-whisker-style plot showing the distribution of the 1m load average
during the test. (CPU usage itself is generally a pretty bad measure of...
CPU usage.) What problems are you hoping to catch?
Just curiosity.
We have a set of tools which capture per-process utilization for
cpu/mem/disk/etc. I wonder if we could implement this into your work?
I somebody can get those tools to log that data in the gate then I can
try to make a chart of it :)
