FME Flow

We are running FME Server 2013 Data Streaming which is driven from a MapGuide site and outputs PDF files. This is quite a complex workspace which generates logs up to about 2MB per request. I would like to be able to turn down the degree of logging to just ERROR if possible. Some of the other services seem to have the option in the .properties file to set the DEBUG_LEVEL = SEVERE. This does not appear to be an option in the Data Streaming config file. I tried adding it anyway with no success.  Anyone have any thoughts? Am I missing something basic here?  Thanks, J  

Hi all, Less a question, more an answer. I know this came up on FMETalk, so I wanted folk to know that we added a "humouring" device to FME Server in 2013.  Whenever you run a data download/job submitter process, you get a spinny wheel thing with an elapsed time counter.    Hope this is useful  Cheers  Mark
