On the *No Sheep* blog, Zachary Tirrell defines the `load average`_
|
|
on GNU/Linux operating system:
|
|
|
|
"In short it is the average sum of the number of processes
|
|
waiting in the run-queue plus the number currently executing
|
|
over 1, 5, and 15 minutes time periods."
|
|
|
|
Be aware that Load on Linux and BSD are different things, high
|
|
`load on BSD`_ does not means high CPU load.
|
|
|
|
Glances gets the number of CPU core to adapt the alerts.
|
|
Alerts on load average are only set on 15 minutes time period.
|
|
The first line also displays the number of CPU core.
