Description Sai Kiran Kanuri 2007-07-18 13:16:22 UTC
Description of problem:

Under Section 3.2.16 related to /proc/loadavg

the following text is mention in the Deployment guide.

"3.2.16. /proc/loadavg

This file provides a look at the load average in regard to both the CPU and IO
over time, as well as additional data used by uptime and other commands. A
sample /proc/loadavg file looks similar to the following:

0.20 0.18 0.12 1/80 11206

The first three columns measure CPU and IO utilization of the last one, five,
and 10 minute periods. The fourth column shows the number of currently running
processes and the total number of processes. The last column displays the last
process ID used."


The time interval i believe should be last one min, five mins & fifteen mins
interval rather than ten min interval.

Comment 1 Luis Claudio R. Goncalves 2007-08-15 22:01:51 UTC
Load avg has to do with number of processes ready to run (in the run queue,
waiting for a CPU share), not only CPU and IO usage.

Comment 3 Luis Claudio R. Goncalves 2008-02-01 10:36:10 UTC
And yes, the values refer to the last 1, 5 and 15 minutes. Sorry for not paying
attention to this detail.

Comment 4 Don Domingo 2008-02-03 22:57:46 UTC
corrected in source. also added:

<para>In addition, load average also refers to the number of processes ready to
run (i.e. in the run queue, waiting for a CPU share.</para>

setting this bug as MODIFIED. thanks Luis, K. Sai!
