We had a problem with the EPiServer Scheduler and we wanted to enable logging for it. Here is a step by step procedure for how to do this.
Go to local services:
Find the EPiServer Scheduler Service in the list, right click and select Properties:
Stop the service, set the Start parameters to the following: SVCDEBUG path_to_log_file, then start the service again:
Then go to the path you entered(it must be a folder that exits on the server). There you will see the log file.
The log file will look like this:
A big thanks to Steve Celius for showing us how this could be done!
