Building Orbit Payments' telemetry, where logs are both the SOC's eyes and the auditor's evidence, as a ring of eight segments that a signal follows clockwise around a central analytics hub — sources, collect, parse, time, enrich, store, health and serve — with 3,412 events received for 3,412 sent and none lost. On the right, pipeline health: a 4.8-million-event forwarder backlog now buffered to disk with retries, a database clock 181.2 seconds fast caught by a drift check, a parser canary cutting failures from 0.31% to 0.02%, and a replay of 2,026,410 events with 12 failures left; and evidence you can trust: a hash chain verified for batch 0412, write-once storage that denies deletes, and storage tiers sized to how the data is searched, since under 5% of searches reach beyond 30 days.

Logging & Telemetry Engineering — The Telemetry Ring

A deeply technical mid-level course that builds the telemetry every detection, investigation, and audit depends on. Follow a security event clockwise around the telemetry ring — Sources, Collect, Parse, Time & Integrity, Enrich, Store, Health, Serve — keeping the signal complete, correctly timed, tamper-evident, retained, and usable, with real engineer commands across auditd, Fluent Bit, Kafka, chrony, WORM storage, and OpenSearch. Four hands-on activities in every lesson.

What you'll learn

  • Design telemetry backwards from the questions detection, investigation, and audit must answer.
  • Collect events losslessly with buffering, acknowledgement, backpressure, and a secured path.
  • Parse and normalize every source into one schema, and make time and integrity trustworthy.
  • Enrich, tier, retain, monitor for silent failure, and serve fit-for-purpose signal.
