PostHog error tracking for Go
— the description by PostHog

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

This skill provides guidance on integrating PostHog error tracking into Go applications. It covers the essential setup, configuration of environment variables, and best practices for capturing exceptions. The skill also details how to manage issues through PostHog, including manual and automatic assignment, alerting configurations, and monitoring strategies to ensure effective error resolution.

What it does

  • Guides the integration of PostHog error tracking SDK into Go applications.
  • Provides best practices for using environment variables for sensitive configuration.
  • Explains how to configure automatic issue assignment rules based on exception properties.
  • Details how to set up alerts for new, reopened, or spiking issues via Slack, Discord, or webhooks.
  • Describes how to assign issues to specific teammates or roles for better triage.
  • Outlines methods for monitoring and searching issues within the PostHog dashboard.

When to use it

  • When you need to implement robust error tracking in a Go-based service.
  • When you want to centralize error reporting and automate issue assignment to specific teams.
  • When you need to set up real-time notifications for critical application errors.
  • When you need to analyze error trends or spikes to identify deployment issues.

Advantages

  • Enables seamless integration with existing Go error handling patterns.
  • Supports automated triage through configurable assignment rules.
  • Provides flexible alerting options to keep teams informed of critical issues.
  • Facilitates better debugging through stack trace analysis and issue properties.

Usage examples

“How do I initialize PostHog error tracking in my Go application?”
The skill instructs you to use the PostHog Go SDK, emphasizing the use of environment variables for keys and enabling autocapture for exception tracking.
“How can I notify my team when a specific error occurs in Go?”
You can configure alert rules in the PostHog error tracking settings to trigger notifications via Slack or webhooks based on specific exception properties.

PostHog error tracking for Go

This skill helps you add PostHog error tracking to Go applications.

Consult the documentation for API details and framework-specific patterns.

Key principles

  • Environment variables: Always use environment variables for PostHog keys and host URLs. Never hardcode them.

  • Minimal changes: Add error tracking alongside existing error handling. Don't replace or restructure existing error handling code.

  • Autocapture first: Enable exception autocapture in the SDK initialization before adding manual captures.

  • Source maps: Upload source maps so stack traces resolve to original source code, not minified bundles.

  • Manual capture for boundaries: Use captureException() at error boundaries and catch blocks for errors that don't propagate to the global handler.

Fingerprints - Docs

Every captured exception is assigned a fingerprint. This fingerprint is used to group similar exceptions into issues. This page covers how fingerprints are generated, how they're used, and how you can override them when capturing exceptions.

Fingerprint and issue grouping

Every exception has a fingerprint, whether generated or defined by the user. Each fingerprint links to exactly one issue. Exceptions that share the same fingerprint define an issue.

Multiple different fingerprints can point to the same issue (a many-to-one relationship) if you merge issues.

How are fingerprints generated?

Fingerprints are built iteratively using components of the exception event. The flowchart below shows how fingerprints are generated.

flowchart LR A[Add exception type to fingerprint] --> B{Stack trace<br/>available?} B -->|No| C[Add error message to fingerprint] C --> D[Final fingerprint] B -->|Yes| E{In-app frames<br/>exist?} E -->|No| F[Add first frame to fingerprint] E -->|Yes| G[Add in-app frame to fingerprint<br/>Priority: resolved > unresolved] F --> D G --> D

The flowchart in text

Fingerprints are generated by considering the following in combination:

  1. The exception type

  2. If there's no resolved stack trace, add the error message to the fingerprint

  3. If there are stack traces but no in-app frames (frames from your code, not a dependency), use the first frame of the stack trace

  4. If there are stack traces, in-app frames, and source maps available, use the resolved in-app stack frames

  5. If there are stack traces, in-app frames, and source maps not available, use the first in-app stack frame

In some languages, like Python, one error can trigger another, creating a chain of linked exceptions. PostHog records the entire chain in the event and generates a single fingerprint for it.

Ensuring accurate fingerprints

Resolved stack traces are critical for accurate fingerprinting. Without accurate stack traces, PostHog cannot group exceptions consistently. If you have not uploaded source maps, follow the source map guide to do so.

This also means that if the exception type or message changes from one version to the next, the fingerprint will change.

When are generated fingerprints used?

Fingerprints are used to group similar exceptions into issues automatically. Automatic issue grouping is only done when:

You can find details about how issue grouping works in the issues and exceptions guide.

Customizing fingerprints

Fingerprints can be manually set during exception capture. This is a very useful way to group exceptions that are not related to each other. You can find examples of how to do this in the custom issue grouping section.

You can also learn more about grouping issues using rules in the grouping issues guide.
