1) Load average is the average number of threads(processes) either running on the cpu or waiting in the run queue. (Rule of thumb, 100% utilization equates to the number of cores. So, on a dual core system a load average of 2 means the system is fully utilized. Anything higher means the system is overtasked. This is not necessarily a bad thing, if it is only for short periods of time the system should be able to "catch up".) http://en.wikipedia.org/wiki/Load_(computing) 2) User means % time spent executing code in user space 3) System means % time spent executing code in kernel space
https://engineering.purdue.edu/ECN/Support/KnowledgeBase/Docs/20020202114659 I would probably focus on triggering alerts based on load average... (Google for "load average alerting" for further info). PLEASE USE GOOGLE before asking questions to this list. --brian On 7/23/07, vit <[EMAIL PROTECTED]> wrote:
