Top Forums UNIX for Advanced & Expert Users Sun: High kernel usage & very high load averages Post 98128 by jim mcnamara on Monday 6th of February 2006 11:04:48 AM

It appears that you have a lot of context switching - that is why the kernel is active.

You may want to look at how priorities are set on the processes that are getting moved in/out. If the processes are not stuck in a loop, you can clear the traffic by letting one or two processes get through a little faster.

Your system does not appear to be I/O bound, so it has to be CPU contention.

FWIW - It also looks like your swap is pretty close to being maxed out as well, like 95% of it is used.

NAME
cfetoolgraph - create graphs from a cfetool database SYNOPSIS
cfetoolgraph name [--path|-p directory name] [--daily|-d] [--weekly|-w] [--yearly|-y] [--timestamps|-T] [--resolution|-r] [--help|-h] DESCRIPTION
The cfetoolgraph command dumps graphs of averages for visual inspection of the normal state database. The files are in a format viewable by "gnuplot" or "xgmr" or other graphical plotting program. The command generates three or four files in a subdirectory of the database directory with a name beginning with either "daily", "weekly" or "yearly", then "-", then either "snapshot" or the current time, if the -T option is used. The files are named "average", "stddev", and "graph". The "graph" file contains both the averages and standard deviations, useful for plotting with error bars. If a histogram file is present, a fourth file named "distr" will also be created, plotting the distribution of fluctuations about the mean value. If the -d, -w and -y options are all omitted, the default is to only graph the weekly database. OPTIONS
--path|-p directory name The directory in which the database specified by name can be found. --daily|-d Graph the daily averages database. --weekly|-w Graph the weekly averages database. --yearly|-y Graph the yearly averages database. --timestamps|-T Time-stamp the output filenames with the current time, in order to give a unique name. --resolution|-r Generate high resolution data (), instead of averaging data over periods of one hour to generate simpler and smoother graphs. --help|-h Prints a short help message and then exits. EXAMPLE
% cfetoolgraph temperature --path /my/path --resolution Create graph files of the weekly database in high resolution in the "/my/path/temperature/weekly-snapshot" directory. AUTHORS
