#
# Usage:
# --------------
# Link this file snmp__gwia_msgs_ to your nodes servicedir [/etc/munin/plugins] 
#
# as: 
#   snmp_<host>_gwia_msgs_<pos>  
#
# with:
#   <host> = Name or IP-Number of host 
#   <pos> = table index of the GWIA Object
# 
# E.g.
#    ln -s /usr/share/munin/plugins/snmp__gwia_msgs_ \
#    /etc/munin/plugins/snmp_foo.example.com_gwia_msgs_0
# ...will monitor a single GWIA object on host foo.example.com. 
#
# Parameters
#	community - Specify wich community string to use (Default: public)
# 	port - Specify which port to read from (Default: 161)
#	host - Specify which host to monitor (Default: Read from link in servicedir)
#	pos - Specify which table Object to read (Default: Read from link in servicedir, 
# 
# You may adjust settings to your need via configuration in plugin-conf.d/munin-node:
#   [snmp_*_gwia_msgs_*]
#   env.port <your_port_number>
#   env.community <your SNMP community string>
#   env.pos <your objects table position. Values: 0,1,2,..> 
#   env.host <name or IP of your host>
#
# Parameters can also be specified on a per GWIA basis, eg:
#   [snmp_foo.example.com_gwia_msgs_1]
#   env.port 166
#   env.community example
