# Datadog Output Plugin This plugin writes to the [Datadog Metrics API](http://docs.datadoghq.com/api/#metrics) and requires an `apikey` which can be obtained [here](https://app.datadoghq.com/account/settings#api) for the account. If the point value being sent cannot be converted to a float64, the metric is skipped. Metrics are grouped by converting any `_` characters to `.` in the Point Name.
