  2. Configure your integration similar to core integrations.

Configuration

  1. Edit the gnatsd_streaming.d/conf.yaml file in the conf.d/ folder at the root of your Agent’s configuration directory to start collecting your GnatsD streaming metrics. See the sample gnatsd_streaming.d/conf.yaml for all available configuration options.

  2. Restart the Agent
