# Configuration variables
# vservers - specify the vservers to include in the graph (default: all)
# limits - if true, turn on limit graphing (default: false)
#
# NOTE: If no configuration variables are set, the defaults will be used
# Example /etc/munin/plugin-conf.d/munin-node
#
# The first group monitors the vservers named "vserver1 vserver2
# vserver3 vserver4" and looks to see if the resource limit has been
# breached, if so it sends a message to nagios via send_nsca, and
# sends an email to notify that this has happened.
#
# The second monitors the vservers "vserver5 vserver6 vserver7" and
# has no limit notifications turned on.
#
# The third monitors all vservers on the system, in one graph, and it has
# no limit notifications defined.
#
# You can use any combination of these to fit your needs.
