I have created a custom model. When this model is run, it shows a process dialog which has some log information. I want to write that log information into the text file for further analysis.
Does anyone know how can I do this?
That log file information can be enabled and is written out to History log file. I would recommend exporting your model as a python script. You can then open up the .py file in any text editor to execute your text file writing/logging while the script is running. Alternatively, using python you can read through the history log file and pull out what you want.
