Kong

Agent Check

Supported OS:

Overview

The Agent’s Kong check tracks total requests, response codes, client connections, and more.

Setup

Installation

The Kong check is included in the Datadog Agent package, so you don’t need to install anything else on your Kong servers.

Configuration

Edit the kong.d/conf.yaml file, in the conf.d/ folder at the root of your Agent’s configuration directory. See the sample kong.d/conf.yaml for all available configuration options:

init_config:

instances:
    # Each instance needs a `kong_status_url`. Tags are optional.
    -   kong_status_url: http://example.com:8001/status/
        tags:
        - instance:foo
    #-   kong_status_url: http://example2.com:8001/status/
    #    tags:
    #    - instance:bar

Restart the Agent to begin sending Kong metrics to Datadog.

Validation

Run the Agent’s status subcommand and look for kong under the Checks section.
