need log file option

[severach]

When things go wrong I'm often asked to prove that and when a file was transferred. lftp solves this with it's robust logging. Here's some log lines from lftp that show when, from, to, and size.

2015-05-27 23:55:12 /home/droxi/INPUT125.txt -> sftp://[email protected]/INPUT125.txt 0-146336 98.2 KiB/s 2015-05-28 00:03:16 sftp://[email protected]/DATA63.txt -> /home/droxi/DATA63.txt 0-701 34.8 KiB/s 2015-05-29 18:23:08 sftp://[email protected]/DATA64.txt -> /home/droxi/DATA64.txt 0-1922 99.0 KiB/s

date: was the file sent in a timely fashion? name/size: which file is it? from: received or sent? to: did it go to the right place? size: was the data complete? speed: is there a network problem? errors: what caused the failure? (lftp does not log errors, but it should)

Hey there. I'm thinking of implementing this. Is there anything else that should be logged besides file transfers and their associated information?

lftp has been sufficient for me so I can only make up ideas you can bounce off others. I can envision at least 3 logging levels.

1: Just transfers and errors that interfere with transfers. 2: More noisy info like connects and disconnects, and normally hidden things like automatic file overwrites. 3: Debugging information including expected errors users could send you to help diagnose program problems.

Try the ssh client with verbose up to -vvv to see how much noise each level generates.
