+=USAGE
+ -== Usage ==-
+Put this file in /usr/share/munin/plugins, `chmod +x` it and
+`ln -s` it to /etc/munin/plugins/esx_<hostname of server to monitor>
+Add a file "esx_" /etc/munin/plugin-conf.d with content like this
+(omit the "# " at the beginning of each line)
+
+---- snip ----
+[esx_*]
+timeout 60
+env.user <username on ESX server or vCenter>
+env.password <password of user on ESX server or vCenter>
+---- snip ----
+
+Then you need to add this host to your munin.conf on the munin server
+(often this is the same as your munin node, i.e. this host) and restart
+munin-node, and wait for the data to populate.
+
+
+ -== Query all hosts of a vCenter ==-
+An alternate way of using this plugin is to link it to
+/etc/munin/plugins/vcenter_<hostname_of_vcenter>
+In this mode, the vCenter server specified in the filename is queried
+for a list of hosts it manages, and graphs are created for all these
+hosts. The option "flatview" is implied in this mode, since one munin
+plugin can only be assigned to one host. The option "vCenter" is ignored
+since the vCenter server is given through the file name. You can, however
+still use the option "flatview" to override the "host_name" under which
+the results are reported. Make sure to read the section below about
+this option!
+
+
+ -== Graphs don't render ==-
+Munin 1.4 has a bug with complex multigraphs like this, see
+http://munin-monitoring.org/ticket/1224 for details and a fix if
+your graphs don't render!
+
+
+ -== Option flatview ==-
+There is an option to render all VMs and Host Systems in a flat
+structure, i.e. not rendering VMs as sub-items of their host.
+This is useful if you frequently move VMs between hosts and want to
+keep the VM graphs running. To activate this option, add
+
+---- snip ----
+env.flatview top_level_entry
+---- snip ----
+
+to the entry in your config file in /etc/munin/plugin-conf.d (see above).
+Be aware that this has some drawbacks:
+ - you cannot have the same VM name in two hosts you monitor
+ (the VM name is the unique identifier for the graphs)
+ - you will only indirectly be able to see which VM is on which host
+ (running VMs will appear in the CPU graphs of their hosts)
+ - it's a flat structure, so it can become quite a long list
+ - because of the way Munin works, all hosts will be queried serially,
+ not in parallel as it would be the case without "flat view" - this
+ MAY lead to timing problems if you have a large number of hosts or VMs
+
+
+ -== Option vCenter ==-
+If you wish to access the host system indirectly through a vCenter, just
+specify this parameter:
+
+---- snip ----
+env.vCenter <address or hostname of the vCenter>
+---- snip ----
+
+This option can be used with or without the "flatview" option. Make sure your
+password and username are valid on the vCenter. The plugin name will still have
+to contain the hostname of the host you want to monitor - be aware that you have
+to use the hostname exactly as it is registered in the vCenter, so IPs and
+hostnames are NOT interchangeable.
+=cut
+
+=ACK
+ -== Ackknowledgements ==-
+I would like to thank VMware for their SDK and the good documentation.
+
+Special thanks go to MEGABIT Informationstechnik GmbH (www.megabit.net)
+who graciously sponsored the development of the "flat view" option
+and the ability to access hosts via vCenter as well as the feature to
+query all hosts on the vCenter.
