# What is snmp__ipoman_ |
| 4 |
# ---------------------- |
| 5 |
# snmp__ipoman is a munin plugin written for the Ingrasys IpomanII 1202 |
| 6 |
# Power Distribution Unit. It should work on any PDU conforming to |
| 7 |
# the IPOMANII-MIB. |
| 8 |
# |
| 9 |
# How do I use it |
| 10 |
# --------------- |
| 11 |
# You can use this plugin on a system with a working munin-node. Here's |
| 12 |
# how: |
| 13 |
# |
| 14 |
# 1. Copy snmp__ipoman_ to the directory where all your munin plugins |
| 15 |
# reside, for example /usr/share/munin/plugins. |
| 16 |
# |
| 17 |
# 2. Make the following symlinks to snmp__ipoman_ in that same directory |
| 18 |
# |
| 19 |
# snmp__ipoman_inletcurrent_ |
| 20 |
# snmp__ipoman_inletpower_ |
| 21 |
# snmp__ipoman_inletvoltage_ |
| 22 |
# snmp__ipoman_outletpower_ |
| 23 |
# snmp__ipoman_outletcurrent_ |
| 24 |
# |
| 25 |
# (If you wonder why. I did not manage to make a plugin which has both |
| 26 |
# the 'snmpconf' and the 'suggest' capabilities. So either I had to make |
| 27 |
# separate plugins for all graph types, or I would have to make |
| 28 |
# assumptions on the number of ports and the address of the ipoman in |
| 29 |
# the script.) |
| 30 |
# |
| 31 |
# 3. Change to the directory where the links to munin plugins reside |
| 32 |
# that are to be run by munin-node, for example /etc/munin/plugins/ |
| 33 |
# |
| 34 |
# 4. Run munin-node-configure-snmp: |
| 35 |
# |
| 36 |
# $ munin-node-configure-snmp --snmpversion=1 <hostname> | sh -x |
| 37 |
# |
| 38 |
# where <hostname> is the hostname or ip address of your ipoman. This |
| 39 |
# will create and print a bunch of symlinks to snmp__ipoman_ which will |
| 40 |
# output current and power usage for all available outlets of the |
| 41 |
# ipoman, and current, power usage and voltage/frequency on all inlets |
| 42 |
# of the ipoman. |
| 43 |
# |
| 44 |
# 5. Restart munin-node |
| 45 |
# |
| 46 |
# 6. Make an entry in your munin server's munin.conf: |
| 47 |
# |
| 48 |
# [<hostname of ipoman as entered in 4.>] |
| 49 |
# address <address of munin-node> |
| 50 |
# use_node_name no |
| 51 |
# |
| 52 |
# 7. Done. |
