A repository of .NET Core runtime diagnostic tools including SOS, the lldb SOS plugin, and global CLI tools like dotnet-dump, dotnet-gcdump, dotnet-trace, and dotnet-counters. It supports dump collection, heap analysis, event tracing, and real-time performance counter monitoring across many OSes and architectures.
Use cases
- collect and analyze memory dumps of .NET Core processes
- monitor performance counters of a running .NET application in real time
- trace events from a live .NET Core app to a file
- analyze the managed heap of a .NET process
- debug .NET Core crashes with SOS in lldb
- investigate memory leaks in production .NET services
When to choose
- you need to diagnose crashes, hangs, or memory issues in .NET Core applications
- you want lightweight CLI tools for live performance monitoring and tracing of .NET apps
- you need SOS/lldb-based debugging on Linux, macOS, or Windows
When to avoid
- you need application-level or APM-style monitoring rather than runtime diagnostics
- you are not working with .NET Core / .NET 5+ runtimes
- you want a GUI-based profiler
