CPU Load vs Utilization
list TJ Yang
Recently a concern was raised by my Xymon user. On Xymon Unix machine's (R3) CPU column is showing CPU load number (0 to 20+). On Windows machine(R2) using bbwin CPU column is showing CPU Utilization number in percentage(0%-100%). Shouldn't we distinguish Unix CPU and Windows CPU columns ? Since they are using two different metric. R1: http://en.wikipedia.org/wiki/Load_(computing)#CPU_load_vs_CPU_utilization R2: http://xymon.com/xymon-cgi/svcstatus.sh?HOST=winxptest&SERVICE=cpu Windows client is using CPU Utilization in % R3: http://xymon.com/xymon-cgi/svcstatus.sh?HOST=voodoo.hswn.dk&SERVICE=cpu This debian Unix machine is using CPU load number. tj -- T.J.

I agree it can be a bit confusing - it's down to the historical heritage of the way Big Brother worked. It will change, but to do so requires some code changes. And probably some standardization of the way performance metris (vmstat for unix, cpu data for WIndows) is kept in the RRD-files. Regards, Henrik
