According to Microsoft, the logs include a variable called
cs-method which represents the method that is taking place during a ftp session call.
I found a reference for a bunch of these methods used in ftp by checking the list of supported commands using this technique.
However I was able to find some more methods such as,
ControlChannelOpened, ControlChannelClosed, DataChannelOpened & DataChannelClosed in the log files.
What are the list of methods available in IIS ftp logging? TIA.
