### Service Discovery
Starting with the 5.8 release, the Datadog Agent ships with service discovery. This feature works for Docker containers and can run on platforms such as Kubernetes, Docker Swarm, and Amazon ECS.

Service discovery makes it possible to define configuration templates for a given Docker image in a configuration store, and to dynamically apply them to new containers on the fly. The Agent will then use these configuration templates combined with container metadata to enable, disable and reconfigure checks dynamically in response to container start/stop events.

For more details on Datadog Agent's Service Discovery, check out the [wiki page](https://github.com/DataDog/dd-agent/wiki/Service-discovery).

### Kong
Kong is an open-source management layer for API.
Kong is an API Gateway and Management solution. Check will send metrics
for the NGINX server in format kong.server.x and for the Database in following format kong.server.x

Examples:
kong.server.connections_handled
kong.server.oauth2_tokens

More details about Kong can be found at https://getkong.org/
