Subject: Query on kernel metrics available
Date: Mon, 19 Nov 2007 12:59:26 +0530 [thread overview]
Message-ID: <200711191259.26502.raju@linux-delhi.org> (raw)
A competing OS vendor is claiming that the Linux kernel has no way to
measure the following:
a. Time spent waiting for page faults in percent
b. Total transfer time for each auxiliary memory in percent
c. Time in percent when one or more tasks were blocked waiting for
memory resources
d. Time spent waiting for page faults in percent
I was wondering if the claims were pure FUD or are measurements
possible -- whether they are actually implemented or not is not
important (at least at this stage). Apologies if the descriptions
aren't very precise; OTOH that leaves us room to interpret the claims
in a favourable (to us) manner :)
TIA and regards,
-- Raju
