Variables in log file names

Hi all,

I'm using several Simple Data Writers to record data, and would like the
file names to be controlled by a variable. I have set one file name
field to:

..\projects\test\${log_prefix}_10user_tests_log.xml

but I only get files called "${log_prefix}_10user_tests_log.xml",
despite having a variable set called 'log_prefix'.
Is what I want to do possible?
Am I going about it the right way?
Is there any way to get the data from separate test runs in separate
files/directories?

	Ronan

With the current version of JMeter you can use the properties/variables:

START.MS - start time in milliseconds
START.YMD - start time as yyyyMMdd
START.HMS - start time as HHmmss

as part of the filename, see:

G'day

I struggled with this sort of thing for a while.

The basic answer is that for each variable reference you have to consider
when it is evaluated.

The name of a log file is evaluated once prior to execution. Since the
variable you are using is not defined at that time it evaluates to its own
name.
