Telegraf v1.39.0 released on 08-06-2026
Telegraf v1.39.0 is out now. It adds a new inputs.gnmi_listener plugin for receiving gNMI push-style telemetry, giving native support for ingesting gNMI telemetry streams.
See the project’s GitHub release notes and the published release artifacts for full details, packages and checksums.
What’s in this release
- New inputs.gnmi_listener plugin to receive gNMI push-style telemetry (PR #18790).
- Controller token support via TELEGRAF_CONTROLLER_TOKEN; secrets support for inputs.azure_monitor client_secret and inputs.http_response token; directory_monitor can preserve timestamps when moving files.
- Many parsers implement the new ParserTimeFunc interface for configurable time handling; processors.parser adds a merge-strategy option; outputs.opentelemetry gains proxy and token-auth support.
Upgrade notes
- No explicit breaking changes are listed for this release; review parser time-handling changes and secret handling if your configuration depends on custom timestamp parsing or existing secret workflows.
- If you need to revert, the release artifacts include packages for many platforms and architectures — install a previous package from the published artifacts to roll back.
Share your experience with the new gNMI listener or any parser/secretstore changes — comments and reports from real usage help catch issues early.
