Standard output from External tasks

Where does "standard output" go for an external task?

If I put a "print" statement in an external task's perl code, where does that output go?

And since I'm asking - what about any "system error messages" like "file not found" if the perl script being executed doesn't exist?

if you don't do the 2>&1 redirect, the error messages end up in iwtrace.log...they'll be the entries without a date/timestamp leader...

haven't done a print statement in an external task other than when I expected to see it on the console, so this is an educated guess, but I'd say it should end up in iwtrace.log as well...

I would recommend using a more controlled logging/debugging framework like log4perl instead of relying on just using the print statement. This will make your code much easier to debug when needed without requiring any change of code. log4perl works just like log4j and has many powerful features, all controlled via a properties like file.

Let me know if you want more information, but it is fairly easy to put in place.

Or - role your own logging module, as we did - which provides timestamps, module-or-file and line number where call came from, job/task information if available, and the logging message (potentially prefaced with "DEBUG", "INFO", "WARNING", or "ERROR" - depending on which call you make).

If you are on 6.x don't bother rolling your own unless you already have created one.
Log4Perl is a very complete tool with many options for log formats and logging mechanisms EG, automatic log rotation, even logging directly to a db if needed.

It's a one stop shop that can be used in a very bare bones format and also handled more complicated situations.

It currently ships with 6.x
