Tenzir Node v5.29.0

This release improves log ingestion by extracting structured data from legacy syslog messages and aligning the bundled schema with Suricata 8. It also republishes the previous release after an error in the earlier release process.

🚀 Features

Extract structured data from legacy syslog content

Mar 13, 2026 · @mavam, @codex · #5902

read_syslog and parse_syslog now extract a leading RFC 5424-style structured-data block from RFC 3164 message content.

This pattern occurs in practice with some VMware ESXi messages, where components such as Hostd emit a legacy syslog record and prepend structured metadata before the human-readable message text.

For example, this raw syslog line:

<166>2026-02-11T18:01:45.587Z esxi-01.example.invalid Hostd[2099494]: [Originator@6876 sub=Vimsvc.TaskManager opID=11111111-2222-3333-4444-555555555555] Task Completed

now parses as:

{
  facility: 20,
  severity: 6,
  timestamp: "2026-02-11T18:01:45.587Z",
  hostname: "esxi-01.example.invalid",
  app_name: "Hostd",
  process_id: "2099494",
  structured_data: {
    "Originator@6876": {
      sub: "Vimsvc.TaskManager",
      opID: "11111111-2222-3333-4444-555555555555",
    },
  },
  content: "Task Completed",
}

Events without extracted structured data keep the existing syslog.rfc3164 schema. Events with extracted structured data use syslog.rfc3164.structured.

Support for Suricata 8 schema

Mar 10, 2026 · @IyeOnline, @satta · #5888

The bundled Suricata schema now aligns with Suricata 8, enabling proper parsing and representation of events from Suricata 8 deployments.

This update introduces support for new event types including POP3, ARP, and BitTorrent DHT, along with enhancements to existing event types. QUIC events now include ja4 and ja4s fields for fingerprinting, DHCP events include vendor_class_identifier, and TLS certificate timestamps now use the precise time type instead of string representation.

These schema changes ensure that Tenzir can reliably ingest and process telemetry from Suricata 8 without data loss or type mismatches.

🐞 Bug Fixes

Fix pipeline startup timeouts

Mar 11, 2026 · @jachris · #5893

In some situations, pipelines could not be successfully started, leading to timeouts and a non-responsive node, especially during node start.

Prevent where/map assertion crash on sliced list batches

Mar 10, 2026 · @IyeOnline, @codex · #5886

Pipelines using chained list transforms such as xs.where(...).map(...).where(...) no longer trigger an internal assertion on sliced input batches.

Graceful handling of Google Cloud Pub/Sub authentication errors

Mar 9, 2026 · @mavam, @codex · #5877

Invalid Google Cloud credentials in from_google_cloud_pubsub no longer crash the node. Authentication errors now surface as operator diagnostics instead.
