Use when a deployed zymtrace backend isn't working as expected — no data appearing in the UI, profiles not arriving, ingest errors, ClickHouse storage full, license / auth failures, slow queries. Walks symptom → diagnosis → fix. Routes between backend (ingest, ClickHouse) and profiler (DaemonSet, CUDA injection) checks. Trigger phrases: "zymtrace not working", "no data in zymtrace UI", "zymtrace UI is empty", "no profiles appearing", "profiles not showing up", "ingest is failing…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Troubleshoot zymtrace Backend

Helps the user diagnose problems on a deployed zymtrace install — the most common one is "no data is showing up in the UI."

This skill spans both backend (ingest, ClickHouse, MinIO) and profiler-side (agent reporting, CUDA injection) checks because "no data" usually requires walking both. Pure profiler-agent issues (CrashLoopBackOff, ImagePullBackOff, OOMKilled, NVML, license rejected on agent side) are handled by [`troubleshoot-zymtrace-profiler`](../troubleshoot-zymtrace-profiler/SKILL.md) — route there if the user's symptom is agent-specific.

## Greet the user

Open warmly. People reaching for a troubleshoot skill are usually frustrated.

> 👋 Sorry zymtrace isn't behaving — let's find it. Tell me what you're seeing (e.g. "the UI loads but no profiles", "ingest pods crash-looping", "got a license error") and I'll walk the diagnosis with you.

How to install

The exact contents, by fingerprint
mdr add zystem-io/zymtrace-skills/troubleshoot-zymtrace-backend@sha256:8cbdd4457b1158b6

The line at the top of this page pins the label git:20260605.f5be030, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
