# 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.

[tokens]: https://metrics.librato.com/account/api_tokens

## Global configuration options <!-- @/docs/includes/plugin_config.md -->

In addition to the plugin-specific configuration settings, plugins support
additional global and plugin configuration settings. These settings are used to
modify metrics, tags, and field or create aliases and configure ordering, etc.
See the [CONFIGURATION.md][CONFIGURATION.md] for more details.

## Secret-store support

This plugin supports secrets from secret-stores for the `api_user` and
`api_token` option.
See the [secret-store documentation][SECRETSTORE] for more details on how
to use them.
