The 'load average' is the average number of processes (programs) that were waiting to run during the last period. Our long term averages use a five minute average. The daily analysis uses the one minute average.
Load Running Wed Peak Wed Average 24 hr 24 hr (1) Peak ========================================= 1 20.1 16.4 0.0 0.1 2 14.7 8.2 0.8 4.9 3 15.5 9.2 9.9 14.2 4 13.4 11.6 15.4 12.8 5 9.3 12.0 16.5 12.1 ----------------------------------------- % < 5 = 73.0 57.4 42.6 44.1 ----------------------------------------- % > 5 = 27.0 42.6 57.4 55.9 ----------------------------------------- <snip...> Note: (1) - This is the running average for Wed. peak usage periods since logging started.Again in the above example, during the Wed. peak utilization period, 55.9% of the one minute load average readings were over 5.0. (...a very bad day)
The table data represents the distribution of load averages for:
