Telegraf v1.38.2 released on 30-03-2026
Telegraf v1.38.2 is out now. Users affected by unreadable configuration directories, negative collection offsets, OPC UA session interruptions, SNMP/SIP/ping edge cases or CloudWatch dimension limits should see targeted fixes and improved stability.
See the project’s GitHub release page for the full release notes, downloads and SHA256 checksums for each package.
What’s in this release
- Agent now errors if the configuration directory is not readable and rejects negative collection_offset values.
- Inputs updates: startup errors from input models are added to gather statistics; inputs.opcua_listener now parses namespace prefixes and nested browse paths inside event fields and resumes metric collection after OPC UA session loss; inputs.ping, inputs.sip and inputs.snmp have targeted fixes (no spurious timeout warnings, correct Via hostname usage, and OID increase check disabled).
- Outputs and packaging: outputs.cloudwatch supports up to 30 dimensions and outputs.heartbeat skips selfstat collection when status is not configured; multi-platform packages and SHA256 checksums are available for a wide range of architectures.
Upgrade notes
- No explicit breaking changes are listed, but several dependency bumps (including pgx moved to v5 and updates to Google and AWS libraries) may affect integrations — validate your integrations and rebuild where necessary before rolling out.
- If you need to roll back, install the previous release package matching your OS/architecture and verify the SHA256 checksum before deployment.
