Log API metrics like request count, request size, response status and latency to the local Datadog agent.


Configuring the plugin is straightforward, you can add it on top of an API (or Consumer) by executing the following request on your Kong server:

$ curl -X POST http://kong:8001/apis/{api}/plugins \
    --data "name=datadog" \
    --data "config.host=" \
    --data "config.port=8125" \
    --data "config.timeout=1000"
