Fluent-bit Datadog Plugin

How to Integrate Fluent-bit Datadog Plugin with Apica Ascent

1. Introduction

This guide explains how to send logs with the Datadog plugin from Apica Ascent to Datadog with Fluent-bit, and how to view them.

2. Configure the Datadog Plugin in Fluent-bit

Update your Fluent-bit.conf with an output for the Datadog Plugin:

[OUTPUT]
    Name   datadog
    Match  ascent_logs
    Host   <datadogRegionURL>
    TLS    on
    Apikey <apiKey>

Datadog region URLs:

US:  http-intake.logs.datadoghq.com
EU:  http-intake.logs.datadoghq.eu
US3: http-intake.logs.us3.datadoghq.com
US5: http-intake.logs.us5.datadoghq.com

This output should be combined with an input such as the HTTP plugin.

Restart Fluent-bit with systemctl restart fluent-bit and check the status with systemctl status fluent-bit to verify that it’s running correctly.
