uptime

[emilio500]

whats the range of numbers displayed by uptime's "load average"? i mean, looking up the "load average", how can i get the percentage of cpu load?

Thank you. [sig][/sig]

IIRC the numbers for the load/avg is the percent. As in, multiply it by 100 and there's you %.

The 3 parameters in the command uptime are the 15 sec, 1 min and 15 min run queue lenghts. They represent the amount of "jobs" that ran between those times,this is on average.

Correct me if i'm wrong (I don't have access to any man pages at the moment) but I think I can add something.

The three load average figures that [tt]uptime[/tt] displays are values for the:

last minute, last 5 minutes, last 15 minutes

My understanding is that "Load Average" can be defined as:

The average number of processes in the state 'ready-to-run', but not actually running in a certain time period.

So it's the average number of processes that are *waiting* for some processor time.

On multi processor systems (the ones that I've used at any rate) that should read: the average number of processes, divided by the number of processors, that are *waiting* for some processor time.

You can't get % cpu load from a load average figure, the commands [tt]uptime 1[/tt] or [tt]top[/tt] display it though.

As I said, that's from memory, so don't base any homework assignments on it guys...
