Logs are an essential part of observing any service; without them you are flying blind. But collecting and analyzing them can be a real challenge -- especially at scale. Not only do you need to solve the basic task of collecting your logs, but you must do it in a reliable, performant, and robust manner. Nothing is more frustrating than having your logs pipeline fall on it's face during an outage, or even worse, disrupt more important services!

Fear not! In this guide we'll show you how to send send logs from HTTP to another Vector instance and build a logs pipeline that will be the backbone of your observability strategy.

Strategy

How This Guide Works

We'll be using Vector to accomplish this task. Vector is a popular open-source utility for building observability pipelines. It's written in Rust, making it lightweight, ultra-fast and highly reliable. And we'll be deploying Vector as a service.

The service deployment strategy treats Vector like a separate service. It is designed to receive data from an upstream source and fan-out to one or more destinations. For this guide, Vector will receive data from HTTP via Vector's http source. The following diagram demonstrates how it works.

Vector Service Deployment StrategyVector service deployment strategy
1. Vector receives data from HTTP
Vector will accept log data over HTTP.
2. Vector processes data
Vector parses, transforms, and enriches data.
3. Vector transmits data to another Vector instance
Vector will send data to another downstream Vector instance.

What We'll Accomplish

To be clear, here's everything we'll accomplish in this short guide:

  • Accept log data over HTTP.
    • Decode JSON, NDJSON, and text.
    • Enrich your logs with select HTTP headers.
  • Send data to another downstream Vector instance.
  • All in just a few minutes!

Tutorial

  1. Install Vector

    curl --proto '=https' --tlsv1.2 -sSf https://sh.vector.dev | sh
    explain this command

    Or choose your preferred method.

  2. Configure Vector

    cat <<-VECTORCFG > vector.toml
    [sources.in]
    address = "0.0.0.0:80" # required
    type = "http" # required
    [sinks.out]
    address = "92.12.333.224:5000" # required
    inputs = ["in"] # required
    type = "vector" # required
    VECTORCFG
    explain this command
  3. Start Vector

    vector --config vector.toml

    That's it! Simple and to the point. Hit ctrl+c to exit.
