Explore stack trace of a running managed process or from a minidump file
You can install stdump
using one of the following ways:
- Manual: Obtain an archive from the latest release.
- NuGet:
Install-Package stdump
- .NET Tool:
dotnet tool install -g stdump
After installing, there will be two executables: stdump-x86.exe
and stdump-x64.exe
.
Elevated access is unnecessary when the target application operates under the same user account. But for other cases, it might be useful to run the utility under a privileged account.
sudo dotnet tool install stdump --tool-path /usr/local/share/dotnet-tools
sudo /usr/local/share/dotnet-tools/stdump
To display a stack trace of a running program, use its PID or process name.
stdump 12832
stdump w3wp.exe
Or point stdump
to a minidump file.
stdump c:\debug\w3wp.dmp
