# Fluent-bit CPU Plugin

### How to Integrate Fluent-bit CPU Plugin with Apica Ascent

#### 1. Introduction

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

#### 2. Configure the CPU Plugin in Fluent-bit

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

```
[INPUT]
    Name cpu
    Tag  cpu
```

```
[FILTER]
    Name   modify
    Match  cpu
    Add    namespace Fluent-bit
    Add    app_name CPU
 
```

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