+=item B<GraphiteSeparateInstances> B<true>|B<false>
+
+If set to B<true>, the plugin instance and type instance will be in their own
+path component, for example C<host.cpu.0.cpu.idle>. If set to B<false> (the
+default), the plugin and plugin instance (and likewise the type and type
+instance) are put into one component, for example C<host.cpu-0.cpu-idle>.
+
+=item B<GraphiteAlwaysAppendDS> B<true>|B<false>
+
+If set to B<true>, append the name of the I<Data Source> (DS) to the "metric"
+identifier. If set to B<false> (the default), this is only done when there is
+more than one DS.

=item B<AlwaysAppendDS> B<false>|B<true>
+If set to B<true>, append the name of the I<Data Source> (DS) to the "metric"
+identifier. If set to B<false> (the default), this is only done when there is
+more than one DS.

+
+=head2 Plugin C<write_tsdb>
+
+The C<write_tsdb> plugin writes data to I<OpenTSDB>, a scalable open-source
+time series database. The plugin connects to a I<TSD>, a masterless, no shared
+state daemon that ingests metrics and stores them in HBase. The plugin uses
+I<TCP> over the "line based" protocol with a default port 4242. The data will
+be sent in blocks of at most 1428 bytes to minimize the number of network
+packets.
+
+Synopsis:
+
+ <Plugin write_tsdb>
+ <Node "example">
+ Host "tsd-1.my.domain"
+ Port "4242"
+ HostTags "status=production"
+ </Node>
+ </Plugin>
+
+The configuration consists of one or more E<lt>B<Node>E<nbsp>I<Name>E<gt>
+blocks. Inside the B<Node> blocks, the following options are recognized:
+
+=over 4
+
+=item B<Host> I<Address>
+
+Hostname or address to connect to. Defaults to C<localhost>.
+
+=item B<Port> I<Service>
+
+Service name or port number to connect to. Defaults to C<4242>.
+
+
+=item B<HostTags> I<String>
+
+When set, I<HostTags> is added to the end of the metric. It is intended to be
+used for name=value pairs that the TSD will tag the metric with. Dots and
+whitespace are I<not> escaped in this string.
+
+=item B<StoreRates> B<false>|B<true>
+
+If set to B<true>, convert counter values to rates. If set to B<false>
+(the default) counter values are stored as is, as an increasing
+integer number.
+
+=item B<AlwaysAppendDS> B<false>|B<true>
+
If set the B<true>, append the name of the I<Data Source> (DS) to the "metric"
identifier. If set to B<false> (the default), this is only done when there is
more than one DS.
If set to B<true>, attach state to events based on thresholds defined
in the B<Threshold> plugin. Defaults to B<false>.
+ =item B<EventServicePrefix> I<String>
+
+ Add the given string as a prefix to the event service name.
+ If B<EventServicePrefix> not set or set to an empty string (""),
+ no prefix will be used.
+
=back
=item B<Tag> I<String>
=item B<Plugin> I<Name>
Name of the write plugin to which the data should be sent. This option may be
-given multiple times to send the data to more than one write plugin.
+given multiple times to send the data to more than one write plugin. If the
+plugin supports multiple instances, the plugin's instance(s) must also be
+specified.
=back
If no plugin is explicitly specified, the values will be sent to all available
write plugins.
-Example:
+Single-instance plugin example:
<Target "write">
Plugin "rrdtool"
</Target>
+Multi-instance plugin example:
+
+ <Plugin "write_graphite">
+ <Node "foo">
