[hobbit] Load Averages

[Michael McCullen]

Load is a measure of how many processes are running or runnable and is  
not directly related to % of CPU used.  There are cases where Load  
average is through the roof but CPU % is very low, usually when when  
the server is having issues talking to NFS storage or accessing some  
kind of I/O resource.

We generally monitor load average based on number of CPUs in the box.   
Our standard is yellow at 1.5 * # CPUs and red at 2 * # CPUs.  YMMV.
