Error Monitoring Tools Are Expanding Into Full Observability Platforms
Sentry and similar tools have expanded well beyond error tracking into performance monitoring, reflecting a broader trend of point solutions growing into fuller observability suites.
Error tracking tools historically did one thing: capture exceptions and stack traces when something breaks in production. The category has steadily expanded into broader application performance monitoring — transaction latency, slow database query detection, and release health tracking — as teams have wanted unified visibility rather than separate tools for errors versus performance.
This expansion mirrors a pattern seen across developer tooling generally: focused point solutions that prove their value tend to expand into adjacent problems their existing customer base also has, rather than staying narrowly scoped indefinitely.
Our Sentry review covers the current state of its performance monitoring features alongside its core error tracking.
