Logging, and Errors, and Metrics Oh My!
summary
Logs give timestamps and breadcrumbs for replaying user steps, metrics show spikes and how many are affected, and Sentry actually groups unknown exceptions, attaches a session replay video and links events to a DataDog integration so correlations surface. Examples: a jet drifts 150 miles off course with ~145 passengers while cruising at 37,000 feet, and Tesla ships a one‑button bug report with a five‑second clip. The session replay reliably helps recreate and fix the bug.
