Subject Re: how do YOU take text from a jmeter "data writer", when its set to "forever"
Date Fri, 16 Jul 2010 15:49:45 GMT

in a multi threading environment, where threads compete for a logging
resource, you cannot expect order to be preserved (I think).

As you're grepping already, why not throw in a sort? Of course, sorting
by a date string can be tricky, you might want to insert some preprocessing.

If there are timestamps (and there should be), sorting becomes trivial,
though you might need to change a ; or two into spaces.
