1. How to measure system load?
Using a cluster of computers, some of which will awakened as the computing
load on their partners reaches maximum. Looking for a good strategy to
measure load. Several commands seem to offer information.
The simplest I have found is 'uptime,' which advises "system load averages
for 1, 5, and 15 minutes."
Does anybody know what the programmer's idea of "load" entails? CPU
utilization?
Put simplistically, my idea of a 100% loaded system is one on which the
launching of new processes or tasks begins to slow down already-running
processes. I wonder if uptime's idea of load is a good measure of this.
Thanks
