# 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.
