# Plugin to monitor CPU usage, for a selected set of users
|
||||
#
|
||||
# Usage: Place in /etc/munin/node.d/ (or link it there using ln -s)
|
||||
# Add this to your /etc/munin/plugin-conf.d/munin-node:
|
||||
# [cpubyuser]
|
||||
# env.USERS root yann
|
||||
#
|
||||
# If env.USERS is set to ALL, count all logged in users.
|
||||
#
|
||||
# root and yann being a list of the users to monitor.
|
||||
# You need to also make sure that awk is installed
|
||||
#
|
||||
# 2008-12-08 v 1.3.1 Hanisch Elián:
|
||||
# - support for dots in user names.
|
||||
# - fix labels
|
||||
#
|
||||
# 2008-12-01 v 1.3 Hanisch Elián:
|
||||
# - fixes, refactoring and code cleanup
|
||||
# - Users that use cpu but aren't in the USERS env var
|
||||
# are plotted as "others", set others.graph to 'no' if
|
||||
# you don't want this.
|
||||
#
|
||||
# 2008-03-20 v 1.2 fireball: fixed minor screwup, works now ^^
|
||||
#
|
||||
# 2008-01-09 v 1.1 fireball: fixed "-" in usernames, those get replaced by "_" now.
