I tried to pipe the ORPU log output to a file according to the documentation (command-line), but couldn't get it to work.
Logging Offline Results Processing Utility Messages to a File - TestStand 2017 Help - National Instr...
An empty file is created, but it is never populated with any log data - did anyone have any luck doing this?
- I made sure that the log file was created in a user-file area
- Checked after ORPU closed (to make sure it was flushed to disk)
I looked into the ORPU code too (and built it), and when providing the documented arguments as debug parameters, it actually created a log file with content. But still, it doesn't work with the included ORPU that comes with the installation when started from CMD-context or within a sequence.
I would have preferred that ORPU could actually create a log file itself, instead of having to deal with console redirecting.
However, creating a process in C# .NET as below, it is possible to re-direct the logging output, but then I also would have to create a mechanism to auto-start ORPU with this wrapper, if ORPU it was closed. TestStand already have this auto-start feature for ORPU (but then again, without the logging).

var processStartInfo = new ProcessStartInfo

using (Process process = new Process())
{
process.StartInfo = processStartInfo;
process.OutputDataReceived += p_OutputDataReceived;
process.ErrorDataReceived += p_ErrorDataReceived;
process.Start();
// Read the output asynchronously to prevent the buffer to overflow.
process.BeginOutputReadLine();
process.BeginErrorReadLine();
if (!process.WaitForExit(-1))
{
try
{
process.Kill();
process.WaitForExit();
}
catch (Exception)
{
if (process.HasExited)
{
// Ignore if the process is already killed.
Debug.WriteLine("ORPU process is already killed. PID: {0}", process.Id);
}
else
{
throw;
}
}
}
}
}
private static void p_ErrorDataReceived(object sender, DataReceivedEventArgs e)
{
Debug.WriteLine(e.Data);
}
private static void p_OutputDataReceived(object sender, DataReceivedEventArgs e)
{
Debug.WriteLine(e.Data);
}
