HTTP Log: Send HTTP logs to Splunk - Plugin

Send HTTP logs to Splunk

Use the HTTP Log plugin to send Kong Gateway raw text logs to Splunk.

Note: The following example uses Splunk 9.0.2. If you are using a different version of Splunk, check the Splunk documentation for the appropriate method.

To send raw text, use the /services/collector/raw Splunk endpoint.

Logs are sent as JSON objects. See the log format reference for details.

Prerequisites

You have a Splunk authorization token.

Environment variables

SPLUNK_AUTH_TOKEN: The Splunk authorization token.

Set up the plugin

Add this section to your declarative configuration file:

      method: POST
      timeout: 3000
      retry_count: 1

Make the following request:
