observability-edot-python-migrate

A migration guide for replacing the classic Elastic APM Python agent with the Elastic Distribution of OpenTelemetry Python agent. APM means application performance monitoring.

In plain words
What is it for?
Updating dependencies, application code, environment variables, image builds, and startup commands when moving a Python service from Elastic APM to OpenTelemetry instrumentation.
Why use it?
It identifies and removes old agent code and settings so the application uses the newer telemetry setup consistently.

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

observability-edot-python-migrate 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 3d 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.

What it actually says

EDOT Python Migration

Read the migration guide before making changes:

Guidelines

  1. Remove ALL classic APM references: elastic-apm from requirements, ElasticAPM(app) / elasticapm.contrib.* from application code, app.config['ELASTIC_APM'] blocks, and all ELASTIC_APM_* env vars
  2. Install elastic-opentelemetry via pip (add to requirements.txt or equivalent)
  3. Run edot-bootstrap --action=install during image build to install auto-instrumentation packages for detected libraries
  4. Wrap the application entrypoint with opentelemetry-instrument — e.g. opentelemetry-instrument gunicorn app:app. Without this, no telemetry is collected
  5. Set exactly three required environment variables:
    • OTEL_SERVICE_NAME (replaces ELASTIC_APM_SERVICE_NAME)
    • OTEL_EXPORTER_OTLP_ENDPOINT — must be the managed OTLP endpoint or EDOT Collector URL. Do NOT reuse the old ELASTIC_APM_SERVER_URL value. Never use an APM Server URL (no apm-server, no :8200, no /intake/v2/events)
    • OTEL_EXPORTER_OTLP_HEADERS"Authorization=ApiKey <key>" or "Authorization=Bearer <token>" (replaces ELASTIC_APM_SECRET_TOKEN)
  6. Do NOT set OTEL_TRACES_EXPORTER, OTEL_METRICS_EXPORTER, or OTEL_LOGS_EXPORTER — the defaults are already correct
  7. Never run both classic elastic-apm and EDOT on the same application

Examples

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.

observability-edot-python-migrate is a skill published in the GitHub repository elastic/agent-skills (564 stars, last pushed 6d ago), licensed Apache-2.0. It adds 42 tokens to every session and 563 once invoked, about $0.0002 per session on Opus 5. 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.
