Telemetry

Each execution creates an Activity from the Meziantou.Framework.ProcessWrapper activity source. Listen to this source with OpenTelemetry or an ActivityListener to trace the processes your application starts.

// Collect the activities of the current test only (ScopedActivityListener is in Meziantou.Framework)
using var listener = new ScopedActivityListener(new ScopedActivityListenerOptions
{
    SourceNames = ["Meziantou.Framework.ProcessWrapper"],
    SamplingResult = ActivitySamplingResult.AllDataAndRecorded,
});

await ProcessWrapper.Create("dotnet")
    .WithArguments("--version")
    .ExecuteAsync();

var activity = Assert.Single(listener.Activities);
Assert.Equal("process.execute", activity.OperationName);
Assert.Equal(0, activity.GetTagItem("process.exit.code"));
Assert.IsType<string>(activity.GetTagItem("process.executable.path"));

The activity starts when the process starts and stops when it exits. Its status is not set when the execution is canceled. The activity is not the ambient activity of your code: the code that runs after ExecuteAsync keeps its own Activity.Current.

The error description is the message of the exception, so it shows the command as allowed by the log verbosity. The arguments are never added as a tag.
