title: Logging worker processes with Parallel Python
body: <p>I've inherited the maintenance of some scientific computing using Parallel Python on a cluster.  With Parallel Python, jobs are submitted to a ppserver, which (in this case) talks to already-running ppserver processes on other computers, dishing tasks out to ppworkers processes.</p>
  
  <p>I'd like to use the standard library logging module to log errors and debugging information from the functions that get submitted to a ppserver.  Since these ppworkers run as separate processes (on separate computers) I'm not sure how to properly structure the logging. Must I log to a separate file for each process? Maybe there's a log handler that would make it all better?</p>
  
  <p>Also, I want reports on what process on what computer has hit an error, but the code I'm writing the logging in probably isn't aware of these things; maybe that should be happening at the ppserver level?</p>
  
  <p>(Version of the question cross-posted on Parallel Python Forums, I'll post an answer here if I get something there about this from a non SO user)</p>
