## Graphite ## Graphite
The Graphite data format translates Telegraf metrics into _dot_ buckets. A The Graphite data format is translated from Telegraf Metrics using either the
template can be specified for the output of Telegraf metrics into Graphite template pattern or tag support method. You can select between the two
buckets. The default template is: methods using the [`graphite_tag_support`](#graphite-tag-support) option. When set, the tag support
method is used, otherwise the [`template` pattern](#template-pattern) is used.
#### Template Pattern
The `template` option describes how Telegraf traslates metrics into _dot_
buckets. The default template is:
``` ```
template = "host.tags.measurement.field" template = "host.tags.measurement.field"

With enable `graphite_tag_support` option following influx metric -> graphite conversion would happen: #### Graphite Tag Support
When the `graphite_tag_support` option is enabled, the template pattern is not
used. Instead, tags are encoded using
[Graphite tag support](http://graphite.readthedocs.io/en/latest/tags.html)
added in Graphite 1.1. The `metric_path` is a combination of the optional
`prefix` option, measurement name, and field name.
The tag `name` is reserved by Graphite, any conflicting tags and will be encoded as `_name`.
