+#
+# Multigraph munin plugin to monitor Eaton UPS-es through the web interface of the SNMP add-on card.
+# The plugin script simply parses the /PSummary.html page and extracts the values from there.
+#
+# To use this plugin, copy it to the munin's plugin directory (eg. /usr/share/munin/plugins)
+# under the name "eatonups_". Don't change this filename! Follow these steps:
+#
+# 1. Give names to your UPSes, in fqdn style. Like "ups.server1" or "ups.server2". Make sure
+#    you can resolve these names as DNS names from the munin machine. You can simply add them
+#    as entries in /etc/hosts.
+#
+# 2. Then symlink it to munin's configured plugins directory (eg. /etc/munin/plugins) with names
+#    according to the devices you wish to monitor, eg:
+#
+#    eatonups_ups.server1
+#    eatonups_ups.server2
+#
+# 3. In  /etc/munin/munin.conf just add these lines for them. Yes, 127.0.0.1 is correct
+#    because that points to the munin-node address not the UPS address.
+#
+#    [eatonups_ups.server1]
+#        address 127.0.0.1
+#
+#    [eatonups_ups.server2]
+#        address 127.0.0.1
+#
+# 4. Restart the munin node by 'service munin-node restart'.
+#
+#    If all went well, after 5 minutes or so you should have two additional nodes listed
+#    on the Web Interface of munin.
+#
+# Tested & working with Eaton USP model PW9130 1500VA-R, with installed ConnectUPS Web/SNMP Card
+# firmware revision V4.36 with munin v.2.0.14 and Ubuntu LTS 12.04
+# Created in 2013 by robi
+#  v0.2 - fixed frequency graph scale to center at 50Hz (correct value for Europe)
+#  v0.1 - initial version
