Prior plugin version returns wrong results. I'm not sure why. This commit fix the bug however it reduce functionality since there is no way now to include/exclude certain users.

# Plugin to monitor CPU usage, for a selected set of users
|
|
#
|
|
# Usage: Place in /etc/munin/plugins/ (or link it there using ln -s)
|
|
# Add this to your /etc/munin/plugin-conf.d/munin-node:
|
|
# [cpubyuser]
|
|
# user root # required if /proc can't be read from by any user!
|
|
# env.USERS root yann
|
|
# env.OTHER_FIELD others # enable 'others'-list, set the label/field name
|
|
#
|
|
# root and yann being a list of the users to monitor.
|
|
#
|
|
# If env.USERS is set to ALL, count all logged in users, and if set to
|
|
# ALLPROC, *all* users with a running process will be listed, except for root.
|
|
#
|
|
# You need to also make sure that awk is installed
|
|
#
|
|
# 2019-08-30 v 1.4 pcy <pcy@ulyssis.org>:
|
|
# - add USERS=ALLPROC, not relying on a tty or pty being present for user detection
|
|
# - OTHERS_FIELD now defaults to disabled, explicitly give it a
|
|
# value to re-enable it (eg. 'others')
|
|
# - use ps(1) instead of top(1) for easier and more robust
|
|
# parsing/summary calculation
|
|
#
|
|
# 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.
|
|
# set usernames in config accordingly (that is with _)
|
|
#
|
|
#
|
|
# Parameters understood:
|

|

# config (required)
|

# autoconf (optional - used by munin-config)
