Description of mpstat output

I'm wondering where I can find description of mpstat output?.. I'm talking about the output of all available counters presented by mpstat. For instance:

Code:

$ mpstat -Au

What is LOC/s, SPU/s, etc?..

Most of the headings are defined in the man page. Type "man mpstat" to see them.

I don't see LOC or SPU on mine so went looking and found this page where the description appears after the values for LOC, SPU and others:

That's good! Thank you very much! I'm wondering if I can find more detailed description of these types of interrupts...

Since its part of the Sysstat package you might download and review the source code for that to see if it has comments on it. Or you might try using the contact at Sysstat's home page:

Yeah, I though about it. But I found quite good description in WikiPedia: Types of Interrupts
