Telegraf v1.38.4 released on 11-05-2026
Telegraf v1.38.4 is out now. It delivers agent and core robustness fixes (Windows service startup errors are now logged to the configured logger, the log-file directory is created when needed, and the agent resets its secret-counter on reload) together with a set of input/output stability and correctness fixes.
See the GitHub release for the full changelog and review the published binaries and checksums on dl.influxdata.com before upgrading.
What’s in this release
- Agent and core reliability fixes: Windows service startup errors are logged to the configured logger; the configured log-file directory is created when required; the agent resets its secret-counter on reload to avoid secret reuse. Common.adx Close is now safe to call multiple times and OPC UA decoding was improved to support byte arrays.
- Inputs and outputs stability fixes: examples include inputs.diskio honouring host-path environment variables on Linux, inputs.docker locking the stats cache, inputs.kinesis_consumer locking shard consumer persistence, inputs.lustre2 exposing explicit cache/sample/page fields, inputs.opcua disabling auto-reconnect to prevent session floods, outputs.graylog transparently reconnecting when a TCP peer closes, and outputs.timestream returning write-factory errors.
- Dependency and packaging updates: numerous downstream library bumps (for example cloud.google.com/go, google.golang.org/grpc, modernc.org/sqlite, github.com/go-sql-driver/mysql and others) and platform/architecture binaries (RPM, DEB, tar.gz, dmg, zip) published with SHA256 checksums on dl.influxdata.com.
Upgrade notes
- No breaking changes are reported in the release notes; if you build from source or vendor modules, review the dependency bumps for downstream impacts on your integrations.
- If you need to roll back, install a previous Telegraf package from the dl.influxdata.com release archive and verify checksums before deploying.
