# Plugin to monitor CPU usage, 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:
|
|
