ScoutApm Ruby Agent
A Ruby gem for detailed Rails application performance monitoring 📈. Metrics and transaction traces are reported to Scout, a hosted application monitoring service.
What's the special sauce? 🤔
The Scout agent is engineered to do some wonderful things:
- A unique focus on identifying those hard-to-investigate outliers like memory bloat, N+1s, and user-specific problems. See an example workflow.
- View your performance metrics during development with DevTrace and in production via server_timing.
- Production-Safe profiling of custom code via ScoutProf (BETA).
