# Created by Jan Rękorajski <baggins@pld-linux.org> based on vserver_cpu_ plugin.

#
|

# Obtained from https://github.com/munin-monitoring/contrib.git
|
||||
#
|
||||
# Changes by Andras Korn, 2015:
|
||||
#
|
||||
# * Convert to zsh
|
||||
# * Fix to remove dots from vserver names (replace them with _)
|
||||
# * Drop support for old (pre 2.6.19) kernels
|
||||
# * Replace cat | grep | cut pipelines with a single sed
|
||||
# * Add env.stripdomain (a domain name to strip from the
|
||||
# end of vserver names when generating labels; be sure
|
||||
# to include the leading dot)
|
||||
#
|
||||
# Graph Vserver cumulative cpu usage stats
