# Fluent-bit Prometheus Scrape Metrics Plugin

### How to Integrate Fluent-bit Prometheus Scrape Metrics Plugin with Apica Ascent

#### 1. Introduction

This guide explains how to send metrics scraped from Prometheus to Apica Ascent with Fluent-bit, and how to view them.

As this is a metrics input it will require specific output plugins such as Prometheus Exporter or Prometheus Remote Write.

#### 2. Configure the Prometheus Scrape Metrics Plugin in Fluent-bit

Update your Fluent-bit.conf with an input and filter for the Prometheus Scrape Metrics Plugin:

```
[INPUT]
    Name prometheus_scrape
    Tag  prom_scrape
    Host 127.0.0.1
    Port 9090
```

If you have not added one of the required output plugins you can find them in the links below:

[Prometheus Remote Write](https://docs.apica.io/integrations/list-of-integrations/fluent-bit/fluent-bit-prometheus-remote-write-output-plugin)

[Prometheus Exporter](https://docs.apica.io/integrations/list-of-integrations/fluent-bit/fluent-bit-prometheus-exporter-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.
