It looks like you're not actually using lumberjack v2. The import path should be gopkg.in/natefinch/lumberjack.v2 (and the code should be in the corresponding path in your Godeps workspace heirarchy). The line numbers reported by the panic reflect this as well, as they refer to the 1.0 codebase.

Using lumberjackV2 it's working fine. Is there any way to customize the logfile names during log file rotation

natefinch commented 8 years ago

Not now, no. There's just a timestamp appended to the name (before the extension, if any). It's important that the log files have unique names, and it's just easiest to use a timestamp, so you never have to worry about collisions with older files.

Is there a way to zip the old log files?

natefinch commented 8 years ago

Not yet, no... though it's something that has been brought up repeatedly. It's definitely a good idea.
