Get metrics from Gnatsd service in real time to:
If you are using Agent v6.8+ follow the instructions below to install the Gnatsd check on your host. See the dedicated Agent guide for installing community integrations to install checks with the Agent prior to version 6.8 or the Docker Agent:
Run the following command to install the integrations wheel with the Agent:
datadog-agent integration install -t datadog-gnatsd==<INTEGRATION_VERSION>
Configure your integration like any other packaged integration.
Edit the gnatsd.d/conf.yaml file in the conf.d/ folder at the root of your Agent’s configuration directory to start collecting your Gnatsd metrics. See the sample gnatsd.d/conf.yaml for all available configuration options.
Run the Agent’s status subcommand and look for gnatsd under the Checks section.
The gnatsd check is compatible with all major platforms

Note: If you use custom Nats cluster names, your metrics may look like this:
gnatsd.connz.connections.cluster_name.in_msgs
The gnatsd check does not include any events.
This gnatsd check tags all service checks it collects with:
server_name:<server_name_in_yaml>url:<host_in_yaml>gnatsd.can_connect:
Returns CRITICAL if the Agent fails to receive a 200 from the monitoring endpoint, otherwise returns OK.
