# Plugin to monitor CPU share, for a selected set of processes. Tested on Linux.
#
# Author: Stefan Osterlitz
# Based on work of Erik Cederstrand
#
# Usage: Place in /usr/local/etc/munin/plugins/ (or link it there using ln -s)
# Add this to your /ur/local/etc/munin/plugin-conf.d/plugins.conf:
# [process_*]
# env.procs httpd java
#
# httpd and java being a list of the processes to monitor. You may use regex expressions for grep, but watch their conversion to field names.
# ps options may vary.
#
# Parameters understood:
#
# config (required)
# autoconf (optional - used by munin-config)
#
#%# family=auto
#%# capabilities=autoconf
