Remote testing with JMeter
Hello all,
I'm new to the list. Please excuse if this mail is text and HTML I'm
trying to send with Outlook and did say that the message should be plain
text only but I don't really trust M$ to do just that. If it doesn't
work I'll switch to webmail so excuse the possible breach of form.
Now to my problem. I'm tasked with doing a performance test for the
project I'm working for. Pretty basic HTTPS frontend with LOTS of HW
behind it to handle big loads. The load I need to generate will be more
than on PC can drive. So I'll have to build a bigger test harness that
can drive min. 150 HTTPS sessions concurrently indefinitely.
I'm using JMeter 2.1.1 with Java 1.4.2. It's all running fine on my
notebook (WinXP, Internal IP 172.22.1.120) and a second notebook (WinXP,
IP 172.22.1.205). I can even set the second notebook up as a
jmeter-server. Now the jmeter-servers I want to set up are Linux Fedora
Core 4 machines that only run the most necessary stuff so that I can get
more grunt out of them. There should be no X window system of any kind
on the system.
So I have a test server set up with FC4 and it's on 172.22.2.32. Now I
have 2 problems.
1) I've imported a small test jmx to run in text mode so that I can see
that the jmeter is working. When I start it (./jmeter -n -t 'UAT -
Simple Login.jmx') it returns the following:
Created the tree successfully
Starting the test
(.:3172): Gtk-WARNING **: cannot open display:
Now I've searched Google and it seems as if jmeter is trying to do
something with X-windows. Has anybody any idea what I'm seeing? The
jmeter.log said:

Which seems to tell me that something's happening. I've got the hunch
it's just a Linux setup thing.
2) When I run jmeter-server all seems to be fine. Rmi is running, jmeter
is running but when I want to connect the client machine (where jmeter
display runs) gives me the foillowing errors in the jmeter.log:

I hope someone can point me in the right direction to fix this. (As
another info, the 172.22.xx.xx is one subnet!) I don't know where the
127.0.0.1 comes from.
Thanx for the help and the jmeter-user list has already helped a lot! So
thanx 4 all guys (and gals ;-)
Cheers from Wellington (NZ)

Re: Remote testing with JMeter
Posted by sebb <se...@gmail.com>.
The GTK error was mentioned by someone else recently - check the archives.
Non-GUI mode is likely to be better for you than remote mode, as this
is currently not very efficient: all the data has to be sent back to a
single server, which becomes a bottle-neck, or the link to it may.
You may find that a single non-GUI instance of JMeter is sufficient to
run 150 sessions.
If not, use two systems, and combine the data afterwards.
Remove all listeners from the test plan; just save the data in the jtl
file using the -l flag.
Add a summariser if you want to follow the progress of the test.

P.S. Email was in text format.
