# Demo Logs

> Ready-to-use demo log sources in formats like NGINX, Apache, syslog, JSON, and metrics for building and testing your Pipelines.

## Description

Mezmo provides several types of demo logs for you to use in building and testing your Pipelines. These can be especially useful to make sure that your Processors are accurately transforming and routing your data as expected.

## Configuration

The demo log sources are ready to use, you only need to choose which option best matches the type of log data you want to test.

<Note>
  The demo logs consistently push between 25Mb-50Mb of data per day.
