hostname will be truncated without a warning.
-=item B<InterfaceFormat> B<name>|B<address>
+=item B<InterfaceFormat> B<name>|B<address>|B<number>
When the virt plugin logs interface data, it sets the name of the collected
data according to this setting. The default is to use the path as provided by
B<address> means use the interface's mac address. This is useful since the
interface path might change between reboots of a guest or across migrations.
+B<number> means use the interface's number in guest.

=item B<PluginInstanceFormat> B<name|uuid|metadata|none>
When the virt plugin logs data, it sets the plugin_instance of the collected
describes where the hostname is located in the libvirt metadata. The default is
I</instance/name/text()>.

Report additional extra statistics. The default is no extra statistics, preserving
How many read instances you want to use for this plugin. The default is one,
and the sensible setting is a multiple of the B<ReadThreads> value.
