.NET
Dynatrace OneAgent instruments your .NET applications by placing trace statements at strategic locations in your code for code tracing, performance metrics, error detection, dependency tracking, and more.
Not every detected .NET application is instrumented by default. Dynatrace maintains a set of rules to instrument specific processes (for example, IIS application-pools, which you can extend with our own rules). To learn the basics about process group monitoring setup (automatic deep monitoring, custom monitoring rules, and built-in monitoring rules), see Set up process group monitoring.
Capabilities
Dynatrace provides extensive .NET monitoring capabilities:
- OpenTelemetry support for capturing traces and ingesting metrics.
For more information, see - End-to-end transaction tracing of requests to web services, remoting services, queues, and databases. Learn more about services
- OneAgent SDK for custom tracing
- Garbage collection, process metrics, and much more
- Always-on 24x7 production grade CPU profiling
- OneAgent SDK for custom tracing
