Hi,
I want to start JMeter-Tests on several remote computers.
Client-server mode is currently not all that efficient. You will get much better performance running independent JMeters on each node in batch mode.
I need all testresults in one jtl-file for further processing.
On some machines the test start as expected, on some machines nothing happens. The only error-message i detected in JMeter-Log (on machine that starts the tests) is:
12/05/2003 1:26:28 PM ERROR - jmeter.engine.ClientJMeterEngine: java.rmi.ConnectException:

Localhost seems to be wrong but works fine. When i remove the
What do you mean by this? The log suggests that localhost does not "work fine".
If i added localhost to remote-host list, it starts the test, if i add a machine to the list that not starts, i get the message above. For example i have 3 hosts: localhost, machine1 (where the test starts) and machine2 (where the test doesn't start). The behavior is:
remote_hosts=localhost, machine1 -> the test start correctly on all (2) machines, no exceptions remote_hosts=localhost, machine2 -> test starts only on localhost, exception above remote_hosts=machine1 , machine2 -> test starts only on machine1, exception above
From 5 machines i tested to remote-start (all debian/java 1.4), only 1 computer behaves as expected and starts to test, others cause the described exception. I have no idea why, all hosts are listening on 1099 and the error-message is not comprehensible.
remote-host which make problems
from jmeter.properties, remote-tests runs without exceptions.
As expected.
All the remote-machines
are listening on 1099 and there is no output on console and there are no firewalls in use.
The error message says that the initial JMeter cannot connect to the remote server on 127.0.0.1 = localhost.
If you are not running a server on localhost, then just remove it from the list of remote hosts.
JMeter will attempt to start all the remote servers that have been defined.
If I recall correctly, any errors starting remote servers will cause the entire run to fail.
No, in this case only some servers run the test.
