Datadog APM Plugin

The datadog APM plugin allows using time series data from Datadog to make scaling decisions.

Agent Configuration Options

apm "datadog" {
  driver = "datadog"

  config = {
    dd_api_key = "<api key>"
    dd_app_key = "<app key>"
    dd_api_rate_per_sec = "200"

    site = "datadoghq.eu"
  }
}

• dd_api_key (string: <required>) - The Datadog API key to use for authentication.

• dd_app_key (string: <required>) - The Datadog application key to use for authentication.

• dd_api_rate_per_sec (string: "") - Maximum rate limit to apply to the underlying HTTP client used to query the Datadog API. The value must be an integer. If omitted, the plugin does not limit requests to the Datadog API.

• site (string: "datadoghq.com") - The Datadog site to connect to.

The Datadog plugin can also read its configuration options via environment variables. The accepted keys are DD_API_KEY and DD_APP_KEY. The agent configuration parameters take precedence over the environment variables.
