#
# Usage:
# --------------
# Plugin needs to be linked to your servicedir [/etc/munin/plugins]
# with the hostname (host) and the table index (pos) of the POA-Object
# defined in the linkage.
#
#   snmp_<host>_gwpoa_<pos>  
#
# with:
#   <host> = Name or IP-Number of host 
#   <pos> = Table index of the POA Object
#
#
# E.g.
#    ln -s /usr/share/munin/plugins/snmp__gwpoa_ \
#    /etc/munin/plugins/snmp_foo.example.com_gwpoa_1
#
# ...will monitor the first POA-Object on host foo.example.com. 
#
#
# Configuration:
# --------------
# 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 via configuration in plugin-conf.d/munin-node:
#   [snmp_*_gwpoa_*]
#   env.port <your_port_number>
#   env.community <your SNMP community string>
#   env.pos <your table position. Values: 0,1,2,..> 
#   env.host <name or IP of your host>
#
# Parameters can also be specified on a per POA basis, eg:
#   [snmp_foo.example.com_gwpoa_2]
#   env.port 166
#   env.community example
