# This plugin monitors ALL processes on a system. No exceptions. It can
|
||||
# produce very big graphs! But if you want to know where your CPU time
|
||||
# is going without knowing what to monitor in advance, this can help;
|
||||
# or in addition to one of the more specific CPU plugins to monitor
|
||||
# just Apache or MySQL, for example.
|
||||
#
|
||||
# It's not obvious what the graph heights actually mean, even to me.
|
||||
# Each counter is a DERIVE (difference since the last counter reading)
|
||||
# of the CPU time usage (in seconds) accounted to each process, summed
|
||||
# by the process name, so all Apache and all MySQL processes are grouped
|
||||
# together. Processes with no CPU usage at all are ignored. Processes
|
||||
# that die may not appear on the graph, and anyway their last chunk of
|
||||
# CPU usage before they died is lost. You could modify this plugin to
|
||||
# read SAR/psacct records if you care about that.
