Laravel Horizon Setup Guide: Monitor Redis Queues Like a Pro

Introduction

If your website sends emails, processes images, or runs background tasks, you need a reliable way to run and monitor those jobs. Laravel Horizon with Redis gives small teams a simple dashboard and process manager so background work stays fast and predictable. This guide explains what matters for businesses — not just code — so you can keep customers happy and leads flowing.

What Horizon and Redis do for your site

Think of queues as a behind-the-scenes team handling time-consuming tasks so your site stays snappy. Redis is the fast storage where queued jobs wait, and Horizon is the friendly dashboard and controller that runs those jobs and shows you how they’re performing. Together they reduce page slowdowns, improve email delivery, and prevent failed background tasks from piling up.

Why this matters for founders and marketers

Slow or unreliable background jobs can mean delayed welcome emails, broken image uploads, or missed notifications — all of which hurt conversion and trust. A monitored queue system helps you: - Keep lead capture workflows working reliably. - Avoid surprises during campaign spikes. - Spot failing jobs before customers notice.

Simple setup overview

You don’t need to be a sysadmin to get started, but a few configuration steps matter. At a high level: 1. Use Redis as your queue storage and install Horizon in your Laravel app. 2. Define supervisors (groups of workers) for different job types like email or image processing. 3. Run Horizon under a process manager so it restarts automatically and can gracefully stop during deploys.

These steps give you visibility into processed jobs, runtimes, and failed tasks — critical metrics for uptime and customer experience.

How to design supervisors and balancing

Supervisors determine which jobs run where. Design them around business needs rather than technical convenience. - Create separate supervisors for big, memory-heavy jobs (e.g., image resizing) and lightweight jobs (emails). - Use a balancing strategy that fits your traffic: predictable workloads can use fixed distribution, while variable campaigns benefit from automatic balancing. - Size processes based on job type: fewer processes for CPU-heavy tasks, more for I/O-bound workloads.

A good rule: isolate jobs that can crash or leak memory to limit impact on everything else.

Monitoring, alerts, and dashboards

Relying on Horizon’s UI alone is risky — if that server goes down you lose visibility. Combine Horizon metrics with external monitoring for resilient alerts. Essential things to monitor: - Queue length (pending jobs) per queue - Jobs processed per minute and average runtime (watch P95/P99) - Failed jobs and retry trends - Horizon process health and Redis latency

Set simple alert rules: for example, page an on-call if any queue has more than 500 pending jobs for 5 minutes, or if failure rate spikes suddenly. Integrate alerts with Slack, PagerDuty, or email so your team responds quickly.

Deployment and process management (non-technical view)

Treat Horizon like any critical service. Run it under a process manager that restarts it if it crashes and allows graceful restarts during deployments. This prevents jobs from being cut off mid-work and reduces customer impact during updates.

Security and operational best practices

Keep Redis private to your app servers and use network rules and authentication. Regularly review persistence settings (snapshots vs append-only files) so backups don’t cause latency during business hours. Document runbooks that show who to call and what to do when backlogs or failures happen.

Short checklist for busy teams

• Set QUEUE_CONNECTION to use Redis and install Horizon.
• Group supervisors by job type and cap processes for memory-heavy work.
• Use external monitoring and alerting alongside Horizon’s dashboard.
• Run Horizon under a process manager and use graceful shutdowns during deploys.
• Secure Redis with network controls and authentication.
• Write runbooks for backlog and failure incidents.

Real quick examples (why this prevents problems)

• Marketing blast causes a 10x email spike: auto-balanced supervisors shift workers and alerts flag SMTP rate limits so the team throttles safely.
• Image job memory leak: isolated supervisors limit blast radius, and OOM alerts prompt an immediate rollback.
• Redis backup latency: moving queues off the primary during snapshots keeps user-facing tasks smooth.
