# Librato Output Plugin

This plugin writes to the [Librato Metrics API][metrics-api] and requires an
`api_user` and `api_token` which can be obtained [here][tokens] for the account.

The `source_tag` option in the Configuration file is used to send contextual
information from Point Tags to the API.

If the point value being sent cannot be converted to a float64, the metric is
skipped.

Currently, the plugin does not send any associated Point Tags.
