Our review
Pros
  • Generate traces, metrics, and logs through language-specific APIs and SDKs
  • Export processed telemetry to a preferred backend
  • Context propagation, head sampling, and instrumentation libraries
  • Distributed traces connect performance issues across application services.
  • Service maps visualize dependencies and support automatic service discovery.
  • Correlates traces with logs, metrics, and real user monitoring data.
Cons
  • Maturity and platform support vary by language and signal
  • Zero-code instrumentation is available only in supported languages
  • Implementation choices and configuration differ across languages
  • Paid plans start at $31 per host per month with annual billing.
  • Cloud deployment may not suit teams requiring self-hosted operation.
  • Focuses on application monitoring rather than general SDK development.
