Search Logs with PostHog AI

PostHog AI searches and analyzes your application Logs using natural language. Instead of building log queries manually, describe what you're looking for – like "authentication failures in the API service" – and PostHog AI finds matching log entries.

How it works

PostHog AI translates your description into log filters (service, severity, timestamp, and content), returns matching log entries with context, and identifies patterns across results – like recurring error messages or correlated failures.

Cross-product correlation

PostHog AI can correlate logs with other PostHog data, making it easier to investigate issues across your stack:

• Logs + Error Tracking – "Find logs related to the NullPointerException from today's errors" matches log entries to errors
• Logs + Session Replay – "Show logs from the session where user X reported a bug" connects server-side logs to session recordings
• Logs + Traces – "Find logs with trace ID abc123" follows a request flow across services

Try it

Select a prompt to try it out in the PostHog app:

• Show me error logs from the API service in the last hour
• Find all logs related to authentication failures today
• What are the most common error messages this week?
• Show logs from the payment service around 2pm yesterday

Tips for better results

• Name the service – "from the API service" or "in the payments worker" helps PostHog AI filter to the right source
• Specify severity – "error logs" or "warning and above" narrows results to the right level
• Include time context – "in the last hour" or "around 2pm yesterday" scopes the search to the relevant window
• Ask about patterns – "What's the most common error this week?" prompts PostHog AI to aggregate and rank results
