Subject: logging server C-state time?
Date: Mon, 03 Nov 2008 14:47:52 -0500 [thread overview]
Message-ID: <490F5568.2090003@redhat.com> (raw)
Hey folks --
I'm interested in logging the amount of time that server CPUs spend in various
C-states over the course of a complicated job, ideally in a manner I could sync
up with output from sysstat tools. So far all the tools I've seen for power
monitoring seem to be targeted to laptops and interactive use, but I'm looking
for something that's scriptable and doesn't need ACPI battery information, even
if that means relying on indirect measurements of power use like C-states. Any
suggestions?
