OpenTelemetry Transformation Language (OTTL) expert for writing and debugging telemetry transformations in the OpenTelemetry Collector. Use when authoring or reviewing `transform`, `filter`, `tail_sampling` processor configs or `routing` connector configs, debugging OTTL syntax or semantics, transforming traces, metrics, logs, or profiles, or converting data-processing requirements into OTTL statements.
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
# OpenTelemetry Transformation Language (OTTL) OTTL transforms or selects telemetry inside Collector components. This skill is pinned to collector-contrib **v0.163.0**. Function, path, default, and feature-gate availability varies by release; when the user's version differs, verify against the matching upstream tag. Dated OTTL feature-gate status for v0.162.0 and v0.163.0 is in [references/functions.md](references/functions.md#feature-gates-verified-2026-10-25). ## Workflow 1. **Choose the component.** `transform` rewrites, `filter` drops, `tail_sampling` decides whether to retain traces, and `routing` sends telemetry to pipelines. A component controls its available contexts and functions. 2. **Choose the lowest usable context.** Lower contexts can read their parents (for example, a span can read `resource.attributes`), but parents cannot read children. Use `datapoint` for point attributes instead of traversing `metric.data_points`. 3. **Verify every emitted function, then write the statement.** Confirm each function's exact identifier and signature in [references/functions.md](references/functions.md). If an identifier …

How to install
mdr add ollygarden/opentelemetry-agent-skills/otel-ottl@sha256:ee9ce280829e38f9The line at the top of this page pins the label git:20261026.7dc08b2, 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.
