[Benchmarking] JMeter problems on 1cpu benchmarking server.

[Frank Warmerdam]

Folks,

Following up on Andrea's JMeter and summarize script email, I have given it
a spin.  However, I'm running into problems on the 1 cpu benchmarking server
which we were planning to use for JMeter.

in /opt/msmaps:

[fwarmerdam at localhost msmaps]$ cat ecw.sh
#!/bin/bash
jmeter -p jmeter.properties -n -t ecw.xml  -l out.jtl  -Djava.awt.headless=true
[fwarmerdam at localhost msmaps]$ ./ecw.sh
An error occurred:
No X11 DISPLAY variable was set, but this program performed an operation which 
requires it.
[fwarmerdam at localhost msmaps]$ tail jmeter.log

My understanding from Andrea and a web search is that the
java.awt.headless=true should have run things without needing an X11
connection but it does not seem to work.

I tried enabling x11 forwarding on my connection and things do sort of start
but the latency (likely mostly at my end) is so bad I never got a proper
application refresh much less something useful.

Any suggestions?

Best regards,
