How to Gain Full Observability of Your Event Flows
In any event-driven system, understanding the flow of events is key to reliability and performance. An "event" is a record of something that happened in your architecture, such as an inbound webhook, a message from a queue, or a call to an async API. Without observability, you're flying blind. You can't debug issues, monitor performance, or understand how your system is behaving.
This guide provides a comprehensive overview of the Hookdeck Event Gateway's observability features, which are designed to give you full visibility into your event flows. We'll cover how to troubleshoot specific issues, proactively monitor for systemic problems, recover from failures, and analyze trends in your event traffic.
Troubleshooting: Finding Specific Events
When you need to quickly find a specific event, request, or delivery attempt to debug an issue, Hookdeck's search and filtering capabilities are your primary tools.
It's important to understand the distinction between three key entities in Hookdeck:
- A Request is the initial HTTP call received by Hookdeck.
- An Event is the outgoing message Hookdeck queues for a destination. One
Requestcan generate multipleEvents. - An Attempt is a specific delivery of an
Event. AnEventcan have multipleAttempts(e.g., retries).
Hookdeck provides powerful filtering on the Requests and Events pages, allowing you to search by status, source, destination, date, and even data within the request body and headers. This allows you to pinpoint the exact information you need to diagnose a problem.

Proactive Monitoring: Tracking Systemic Failures
Moving from reactive debugging to proactive monitoring allows you to catch systemic issues before they impact many users. Hookdeck's Issues and Notifications are the key features for this.
An Issue is an automatically created tracker for a recurring problem, such as a spike in 5xx errors from a destination. You can configure Issue Triggers to define when an issue should be opened, and set up Notifications to be alerted via Email, Slack, or PagerDuty when a problem is detected.

Recovery: Replaying Failed Events
After you've resolved a problem, Hookdeck makes it easy to recover the failed events using manual or bulk retries. While automatic retries handle transient network issues, manual and bulk retries give you control over recovering from larger incidents. You can retry a single event for testing purposes or trigger a bulk retry for all events associated with a resolved issue.

Analyzing Trends: Understanding Event Performance
For high-level insights, view the metrics on the individual pages for your Sources, Connections, and Destinations. This provides a more granular view of performance, helping to identify bottlenecks and understand traffic patterns for specific parts of your system. For some charts, you can drill down into the data directly to investigate anomalies.

Integrating with External Observability Platforms
For even deeper observability, Hookdeck metrics can be exported to external platforms like Datadog. This allows you to create custom dashboards and set up advanced alerting based on Hookdeck data within your existing monitoring tools.

Conclusion
By leveraging Hookdeck's comprehensive suite of observability tools—from detailed event tracing and proactive issue monitoring to flexible recovery options and performance analytics—you can move from a reactive to a proactive stance. This ensures your event-driven architecture is not only resilient and reliable but also transparent, giving you the confidence to build and scale your systems effectively.
