How is Load Average calculated ?

Slawski

My XG load average is a number between 1.0 and 2.0 mostly sitting at 1.3. This is strange for me because CPU idles at 2-3% most of the time. Normal Linux system with such cpu usage will have load average of less than 0.1.


As XG has a Linux kernel (modified or not - i don't know) - it should calculate load avarage similiary, or not ?

Does anybody know something about that Load Average meaning ?

    Hi Slawek,

    Online definition for Load average is the average system load calculated over a given period of time of 1, 5 and 15 minutes. The maths is same for the XG firewall, based on the fact that it runs on a Linux kernel. If you have dual-cores CPU running the XG firewall, then the load average is normal.

    To check the numbers of cores, you can execute the following command in the Device Console:

    console> system diagnostics show cpu

    Thanks,
