Fluent-bit Prometheus Exporter Plugin

How to Integrate Fluent-bit Prometheus Exporter Plugin with Apica Ascent

1. Introduction

This guide explains how to send expose metrics with Prometheus Exporter and export them to Apica Ascent with Fluent-bit and Prometheus, and how to view them.

You do not have to use Prometheus to scrape and export the metrics, use can use other methods but it’s not possible to use only fluent-bit with the Prometheus Exporter plugin.

2. Configure the Prometheus Exporter Plugin in Fluent-bit

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

[OUTPUT]
    Name     prometheus_exporter
    Match    prom_scrape

This output should be combined with inputs such as the Prometheus Scrape Metrics plugin and a way to scrape and export the metrics.

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