Messenger Newrelic Laravel Package

Product Decisions This Supports

• Observability & Debugging: Enables granular transaction tracking for Symfony Messenger messages in New Relic, improving visibility into async workflows (e.g., background jobs, event-driven processes).
• Performance Optimization: Identifies bottlenecks in message processing (e.g., slow handlers, retries) by correlating message names with transaction latency.
• Roadmap for Async Systems: Justifies investment in Symfony Messenger for high-throughput systems (e.g., order processing, notifications) by reducing blind spots in monitoring.
• Build vs. Buy: Avoids custom middleware development for New Relic integration, reducing technical debt and maintenance overhead.
• Use Cases:
  • Microservices with distributed messaging.
  • High-volume event-driven architectures (e.g., real-time analytics).
  • Compliance-heavy systems requiring audit trails for async operations.

When to Consider This Package

• Adopt if:

  • Using Symfony Messenger (v4–7) with New Relic for observability.
  • Processing messages asynchronously and need per-message transaction tracking.
  • Already invested in New Relic for APM and want to extend coverage to async workflows.
  • Running PHP 8.0+ and Symfony 4.3+.

• Look elsewhere if:

  • Using non-Symfony frameworks (e.g., Laravel, custom queues).
  • Not using New Relic (alternatives: Datadog, Sentry, or custom logging).
  • Messages are synchronous or handled via HTTP (use middleware like NewRelic\Agent directly).
  • Need advanced queue metrics (e.g., retry counts, throughput) beyond transaction names.

How to Pitch It (Stakeholders)

Executives: "This package bridges a critical gap in our observability stack by automatically tracking Symfony Messenger jobs in New Relic. For every message processed—whether it’s an order confirmation, payment webhook, or analytics event—we’ll get a dedicated transaction in New Relic. This turns opaque async workflows into actionable insights, reducing MTTR for failures and validating performance SLAs. Minimal setup (5-minute config change) with zero runtime overhead."

Engineering: *"The package adds a lightweight middleware to Symfony’s Messenger bus, notifying New Relic of each message as a transaction. Key benefits:

• No code changes: Plugs into existing messenger.yaml.
• Symfony 7 support: Future-proof for our upgrade path.
• Extensible: Supports custom transaction names via NameableNewrelicTransactionInterface.
• Low risk: MIT-licensed, 20+ stars, and actively maintained (latest release June 2024). Tradeoff: Limited to New Relic, but aligns with our existing APM strategy."*
