Health > System > Processor : What does unit 'U' mean?

[patient0]

Hi,

It's a bit embarrassing but I seem not to be able to figure out what the 'U' is meant to be for the 'Processor' graph unter "Health".

I did assume that it is load average but for that the numbers are way off for me.

I switched to OPNsense a week ago (running latest 22.7.4) and it runs on SOPHOS SG105r3 hardware. It got an Intel E3930 cpu with 2 cores (and 2GB RAM). The Health graph - with interrupt and processes disabled - is attached.

The load average on the dashboard is reporting "0.32, 0.41, 0.38" right now. Looking at the Health graph the average seems to be much higher and it regularly goes beyond 15.

The documentation did not clear it up for me. Maybe a patient soul could shed some light on that?

Thanks
Thomas

[ U ]tlization as in the legend on the very left. In percent.

Thanks a lot @pmhausen, that clears it up.

It is common knowledge that utilization is in percent? Maybe it would clear things up if the legend text would read 'Utilitzation in %' or 'Utilitzation (%)'.

For interrupts and process 'Number' does not leave any question. But Utilitzation could be in percent or like with load average in relations to the CPUs cores.

Anyway, since it seems clear to anyone else it's probably just me.

Thanks again!

It's just the value regular command line tools like top, ps, vmstat, ... use. So yes, CPU utilization is supposed to be in percent. What varies from operating system to operating system is whether one core is counted as 100% or all of them summed up.
