Question regarding user logging in distributed tests...

[Kirin0 <jc...@yahoo-inc.com>]

I have a .jmx file that I’ve been using to perform tests via command line for
multiple users against a test server.  

The command that I’ve been using to perform the tests is:

Jmeter –n –t BaselineThroughput.jmx –Jusers=#  -l log#.jtl

Where # is the number of simultaneous users I want for the test.  The test
is designed to run for 5 minutes and then exit.  This works fine and results
in a log file where I can distinguish the users results by tn=”Thread Group
1-#” where # ranges from 1 to the number of users requested.  

I am now running a distributed test with 2 engines running on separate
servers and the same setup, except that I start the jmeter-server on each of
the remote clients and then execute with:

Jmeter –n –t BaselineThroughput.jmx –R ###.###.###.###,###.###.###.### 
–Jusers=# -l log#.jtl

Where I'm using real IP addresses (removed here for anonymity) and # users
ranges from 1-5000.

This appears to work fine, results collected, etc, except every entry in the
log file is stored as tn=”Thread Group 1-1”, I would have expected
tn=”Thread Group x-y” where “x” is the remote client number and “y” is the
user # on the remote client.  I am also seeing many less samples than I
would have expected during the 5 minutes the test runs, close to the number
I would expect with only one user.  It is almost as if only one user is
being run, or, all the other sample data is being dropped on the floor.

Is this working correctly? Have I missed something?  Is there a way to
confirm which data was collected from which client?

Thanks,

There was a bug in handling the end of a test in client-server mode.
(It has been fixed in the current code-base and will be in the next
version).  A work-round is to add a pause at the end of the test (e.g.
using Test Action) to ensure all samples have been generated before
the first test stops.

You can add the host-name to the data collected.
Or you can use the __machineName() function in the Thread Group name.
