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. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
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.
And yes, the values refer to the last 1, 5 and 15 minutes. Sorry for not paying attention to this detail.
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!
