What problem does it solve?

Identify why PostHog CDP functions or pipelines fail to deliver events to destinations, produce transformation errors, or exhibit unexpected routing behavior so engineers can quickly prioritize fixes and communicate accurate root causes.

Core Features & Use Cases

• Function discovery: Locate the relevant CDP function by name, destination type, and project association.
• Execution and error analysis: Inspect enabled/disabled state, recent invocations, error rates, and log messages to surface authentication failures, payload validation errors, timeouts, or transformation bugs.
• Trigger and filter validation: Verify event triggers, filter conditions, and project attachment to explain why events may not be routed or processed.
• Destination investigation: Check destination credentials, endpoints, payload formats, and rate limiting or ingestion rejections when the function executes but downstream systems show no data.
• Operational use case: Triage a customer report where a CDP function appears to run but the third-party destination receives no records and produce a prioritized remediation checklist.

Quick Start

Diagnose a CDP function for project "acme" that is executing but not delivering events to the Segment destination and produce a prioritized list of probable causes, evidence to gather, and remediation steps.
