Maintaining a logfile manually is complicated and has no major improvements over just logging to stderr, because nodewatcher is no deamon and can be run manually for debugging purposes. Also, the debug output from subscripts currently is not written to the log file anyway and the debug level is not used eiher. Therefore, the file logging and debug level is removed from nodewatcher, which simplifies the code a bit.
