# What is snmp__ipoman_
# ----------------------
# snmp__ipoman is a munin plugin written for the Ingrasys IpomanII 1202
# Power Distribution Unit. It should work on any PDU conforming to
# the IPOMANII-MIB.
#
# How do I use it
# ---------------
# You can use this plugin on a system with a working munin-node. Here's
# how:
#
# 1. Copy snmp__ipoman_ to the directory where all your munin plugins
# reside, for example /usr/share/munin/plugins.
#
# 2. Make the following symlinks to snmp__ipoman_ in that same directory
#
# snmp__ipoman_inletcurrent_
# snmp__ipoman_inletpower_
# snmp__ipoman_inletvoltage_
# snmp__ipoman_outletpower_
# snmp__ipoman_outletcurrent_
#
# (If you wonder why. I did not manage to make a plugin which has both
# the 'snmpconf' and the 'suggest' capabilities. So either I had to make
# separate plugins for all graph types, or I would have to make
# assumptions on the number of ports and the address of the ipoman in
# the script.)
#
# 3. Change to the directory where the links to munin plugins reside
# that are to be run by munin-node, for example /etc/munin/plugins/
#
# 4. Run munin-node-configure-snmp:
#
# $ munin-node-configure-snmp --snmpversion=1 <hostname> | sh -x
#
# where <hostname> is the hostname or ip address of your ipoman. This
# will create and print a bunch of symlinks to snmp__ipoman_ which will
# output current and power usage for all available outlets of the
# ipoman, and current, power usage and voltage/frequency on all inlets
# of the ipoman.
#
# 5. Restart munin-node
#
# 6. Make an entry in your munin server's munin.conf:
#
# [<hostname of ipoman as entered in 4.>]
# address <address of munin-node>
# use_node_name no
#
# 7. Done.
