How best to track start & end times during a test?
Was wondering how best to track/log start & end times for a load test
within JMeter, in case one doesn't adamantly (and manually) note down the
times. Still important even when you have a fixed test duration as you need
to know what times the test ran to correlate logs.
I notice that JMeter's tabular data in the GUI, when saved as CSV via Save
Table Data button does not log any timestamps for start/end of test.
Similarly, unless I misconfigured settings, seems the CSV output of data
(reported in Summary Report or Aggregate Graph) that is set to save to file
when test runs also does not log start/end times, but it does have a
timestamp column, but hard to decipher for me.
Haven't checked the XML output version, but XML is rather verbose, and I
would prefer a condensed CSV of results instead.
And the JMeter graphs, including the JMeter plugins at
http://code.google.com/p/jmeter-plugins/
also don't seem to display start/end times other than test duration span in
minute/seconds on the X-axis.
Feedback appreciated.
Thanks,
David

Thanks for all the feedback. The debug sampler and JMeter function methods
I can look into. I am using JMeter in GUI mode, so probably can't specify
log file at runtime (don't want to parse the JMeter.log file either).

See if something like this
${__javaScript((${__time()}-${TESTSTART.MS})/1000)} works for you

You could add this to a 'debug sampler' name; inside a 'once only
controller':
[Date=${__time("dd-MM-yyyy",today)}] [Time=${__time("hh:mm",today)}]
This would give you the start date and time for your test

Thanks to the input, I have devised a way to make this work in a 'Summary Report' listener... It's not pretty, but it is functional.
I've included the contents of my 'TG Timer' here. It uses a separate thread group for the timers, because the 'once only' controller ran once per thread, not once per thread group.
The general idea is setup some variables, poke them into parameters (so I can transfer the values across thread groups) and then read and reset them between each thread group - outputting a dummy sampler line with the timestamp (in ms-since-epoch, but you could change this if you like) and the elapsed time since the last time the 'TG Timer' ran... I intersperse these TG Timers between my sequentially running thread groups and "tah dah!" I get timestamps and elapsed times output in the Summary Report.

Hi Robert,
You should take a look at JMeter plugins out there. Some of them give the possibility to switch between relative time (moment 0 - time elapsed) or actual time (time of start - time of last sample).

I would find it quite useful to see this sort of information on the
listeners too in the GUI...
Specifically, I'd like to see execution 'start' and 'end' times, and even
thread 'start' and 'end' times. Ideally we'd have the option to see an
'elapsed' time for the test and the threads as well... Some sort of update
to the Summary listener would be ideal.

Hi,
You can set a log file with passing the -j [log_file] parameter to JMeter
on startup.
On the generated log file you can get the start and end time of the run (if
you are running it in non GUI mode and with auto start).
2011/10/27 18:33:33 INFO - jmeter.engine.StandardJMeterEngine: Running the
test!
2011/10/27 18:34:14 INFO - jmeter.engine.StandardJMeterEngine: Test has
ended
Good Luck,
Shmuel Krakower.
