rrdtool - What means load_one metric Y-Axis in Ganglia/RRD Tool? -

-

i'm using ganglia + rrdtool monitoring web farm. many graphs clear when see load_one metric, don't have y-axis legend.

so, what y-axis means?

thanks.

load_one load average on 1 minute. number of threads (kernel level) runnable , queued while waiting cpu resources, averaged on 1 minute.

the number should interpreted in relation number of hardware threads available on machine , time takes drain run queue. latter can evaluated looking @ 5 , fifteen minute load averages, long these stay reasonable, should ok
