Send logs from Heroku to anywhere

A simple guide to send logs from Heroku to anywhere in just a few minutes.
type: tutorialdomain: sourcessource: heroku_logs

Logs are an essential part of observing any service; without them you'll have significant blind spots. 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, cause the outage!

Fear not! In this guide we'll build an observability pipeline that will send logs from Heroku to anywhere.

Background

What is Heroku?

Heroku is a container-based platform for deploying and managing applications. It's a platform as a service (PaaS) that is fully managed, allowing developers on Heroku to focus on their applications instead of their infrastructure.

Strategy

How This Guide Works

We'll be using [Vector][urls.vector_website] to accomplish this task. Vector is a popular open-source observability data pipeline. It's written in Rust, making it lightweight, ultra-fast and highly reliable. And we'll be deploying Vector as a agent.

Vector daemon deployment strategyVector daemon deployment strategy
1. Your service logs to STDOUT
STDOUT follows the 12 factor principles.
2. STDOUT is captured
STDOUT is captured and sent to a Heroku app.
3. Vector collects & fans-out data
Vector collects data from your platform.

What We'll Accomplish

We'll build an observability data pipeline that:

  • Receives log data from Heroku log drains via Heroku's logplex system.
    • Enriches data with useful Heroku context.
    • Securely receives data via Transport Layer Security (TLS).
  • Send your logs to one or more destinations

All in just a few minutes!

Tutorial

  1. Install Vector

    curl --proto '=https' --tlsv1.2 -sSf https://sh.vector.dev | sh
  2. Configure Vector

    none
  3. Start Vector

    vector --config ./vector.toml
  4. Observe Vector

    vector top
    explain this command
