Simple question -- is there a plugin or easy method to check for processor
usage over either a 1 minute or 5 minute average on linux machines? There's
a check_load plugin, but I can't find anything that would easily function as
a check_cpu plugin.
That's exactly what the load average is - it shows how busy the
processor is/has been over the last 1 minute, 5 minutes and 15 minutes.

Andy,
I was under the impression that load was more indicative on process-wait for
cpu cycles and general system performance than actual cpu usage. For
example, heavy processor wait on disk IO could cause high load without
actually consuming CPU usage, amongst other things. Am I incorrect?
If
Here's one that we use.
It requires SAR - usually that's not a big deal.

Actually, the exact meaning is the average number of process on the CPU
run queue. For example if you have two processes running constantly (ex.
number-crunching applications) you load average will be always 2 (or
higher if there's other programs running).
Since the run queue does not have a
