Fact Summary

Langfuse Tracing Setup

Key Paths

• Langfuse plugin config: /home/dev/.pi/agent/pi-langfuse/config.json
• OMP agent config: ~/.omp/agent/config.yml
• OMP logs: /home/dev/.omp/logs/omp.<date>.log
• Plugin version: pi-langfuse@1.4.3

Langfuse Server

• Host: http://95.111.224.175:19030
• Public key: [REDACTED]
• Secret key: [REDACTED]
• API endpoint for traces: GET /api/public/traces with basic auth (pk:sk)
• Server was healthy (HTTP 200, 35ms response)

Root Cause

• Plugin was registered in the package system but OMP’s plugin system never executed the extension entry point.
• OMP log showed zero extension discovery for any PID.
• pi doctor reported clean, plugin code loaded fine under Bun standalone, but OMP itself never invoked it.

Fix Applied

• Added explicit extensions: entry in ~/.omp/agent/config.yml pointing to the pi-langfuse plugin directory.
• OMP does NOT hot-reload config — requires full process restart.
• Expected log confirmation after restart: 📊 [[infrastructure/port-19030|Langfuse]]: Tracing enabled

Verification Steps

1. Check OMP logs for extension loading messages
2. Query Langfuse API: curl -u pk:sk http://95.111.224.175:19030/api/public/traces?limit=3
3. Confirm totalItems > 0 in response

Pitfalls

• Do NOT grep recursively from ~ for Langfuse references — causes timeout (home dir too large).
• Use targeted find with -maxdepth on known dirs like ~/py, ~/active, ~/audio.
• Cannot restart OMP from within an OMP session — user must do /restart or close/reopen.
