Telegraf v1.38.3 released on 20-04-2026
Telegraf v1.38.3 is out now. It delivers bug fixes and dependency updates that reduce crashes, gather more complete Docker metrics and make OPC‑UA monitoring safer.
See the project’s GitHub release for full notes, SHA256 checksums and platform packages, and download the package or binary for your architecture.
What’s in this release
- agent: per-input collection_jitter can be set to 0s, allowing deterministic scheduling for individual inputs.
- inputs.docker: now lists all containers so non‑running container states are collected.
- parsers.influx: added a guard to avoid a panic on invalid input, reducing crashes when parsing malformed metrics.
Upgrade notes
- Many dependencies were bumped (Google Cloud libraries, aws-sdk-go-v2 group, Prometheus client, modernc.org/sqlite, OpenTelemetry pdata and others); test the release in staging and re‑vendor or rebuild any embedded Telegraf binaries.
- If you must roll back, restore the previous package or binary used in your environment and verify service behaviour before returning to production.
Share any issues or notes on your experience with the new Docker, OPC‑UA or parsing behaviour — feedback helps others decide when to upgrade.
