# Graph Vserver load average
|
|
#
|
|
# Configuration variables
|
|
# vservers - specify the vservers to include in the graph (default: all)
|
|
#
|
|
# NOTE: If no configuration variables are set, the defaults will be used
|
|
|
|
# Example /etc/munin/plugin-conf.d/munin-node
|
|
#
|
|
# The following monitors the load average for vservers 1 and 3:
|
|
#
|
|
# [vserver_loadavg]
|
|
# user root
|
|
# env.vservers vserver1 vserver3

# Changelog
|
|
# version 0.1 - 2007 June 26
|
|
# Andrei Morgan <asm-debian@fifthhorseman.net>
|
|
# - initial author, based upon vserver_resources by Holger Levsen and
|
|
# Micah Anderson, and upon the examples in the munin wiki.
|
|
# version 0.2 - 2008 July 7
|
|
# Micah Anderson <micah@riseup.net>
|
|
# - fix cvirt vs. nsproxy issue with newer kernels by adding $NAMELOC which
|
|
# is aware of VCI_SPACES (> 2.6.19) as well as the older version
|
|
|
|
# If run with the "autoconf"-parameter, give our opinion on whether we
|
|
# should be run on this system or not. This is optional, and only used by
|
|
# munin-config. In the case of this plugin, we should most probably
|
|
# always be included whwn there is a vserver kernel.
