jaeger

jaeger is a skill for Claude Code, Codex from ashish7802/awesome-api-skills. It costs 0 tokens per session (539 once invoked), scanned A, original, MIT.

A guide to Jaeger, an open-source tool for distributed tracing: following one request as it moves through multiple services.

In plain words
What is it for?
It covers setup, OpenTelemetry integration, Grafana integration, trace sampling, storage, scaling, and production troubleshooting.
Why use it?
It helps find where a request slows down or fails when logs from many services are difficult to connect.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

jaeger scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Quick Start

Jaeger receives distributed traces (usually from OpenTelemetry), stores them, and provides a UI to visualize the exact lifecycle of a request as it hops across multiple microservices.

docker run -d -p 16686:16686 -p 4317:4317 jaegertracing/all-in-one:latest

Production Patterns

Trace Sampling

Do not trace 100% of your requests in production. Use probabilistic sampling (e.g., 1%) or tail-based sampling (recording 100% of errors but only 1% of successful requests) to prevent Jaeger's storage backend from imploding.

Architecture & Scaling

Storage Backends

The all-in-one Docker image uses in-memory storage and will lose data upon restart. For production, you must configure Jaeger to use a durable storage backend like Elasticsearch or Cassandra.

Error Recovery

If the Jaeger UI is incredibly slow, it is likely due to the underlying Elasticsearch database struggling to aggregate massive trace volumes. Optimize your ES cluster and ensure you are aggressively rotating old indices.

Security Notes

Jaeger's UI has no built-in authentication mechanism. When deploying to Kubernetes, place it behind an OAuth2 Proxy or an Ingress controller configured with strict IP whitelisting.

Relationships

Prerequisites: opentelemetry

Works Well With: grafana

Why use this skill

Use this when your agent works with jaeger — structured patterns beat pasted docs and prevent common hallucinations.

AI pitfalls

  • Using outdated SDK or API versions from training data
  • Inventing environment variable names
  • Omitting error handling and retry logic

Production checklist

  • Secrets in environment variables, not source code
  • Error handling and logging in place
  • Rate limits and timeouts configured

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

jaeger is a skill published in the GitHub repository ashish7802/awesome-api-skills (13 stars, last pushed 9d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 539 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
