jmeter -distributed testing - log file is incomplete

I have setup jmeter in distributed testing with 1 master and 2 slaves on AWS and things seem to be running with following command:

./jmeter.sh -Djava.rmi.server.hostname=127.0.0.1 -n -t Ping.jmx -R 127.0.0.1:24001,127.0.0.1:24002 -l out.csv

Ping.jmx is configured with 20 threads for a ramp up of 20 secs. The issue is out.csv does not have all the data from remote servers for all requests made. I expect 40 requests made from 2 remote servers. I can see the jmeter-server.log on remote servers and see that all 20 threads are being executed. The size of the log file has only 4 requests all the time irrespective of the number of threads. Any pointers?

The out.csv looks like this: [root@ip-10-0-2-49 bin]# vi out.csv timeStamp;elapsed;label;responseCode;threadName;success;bytes;sentBytes;grpThreads;allThreads;Latency;SampleCount;ErrorCount;Hostname;IdleTime;Connect

I cannot reproduce you issue so my expectation is that your configuration is not very correct, you need to provide more details regarding it.

JMeter same host distributed execution

Few recommendations:

  1. Running JMeter in distributed mode on a single machine doesn't make any sense, it only causes overhead required to keep master and each other JMeter instance running. In order to get the maximum performance from a single JMeter you need to follow recommendations from 9 Easy Solutions for a JMeter Load Test “Out of Memory” Failure article. Also it worth seeing JMeter Distributed Testing Step-by-step guide just in case you haven't got a chance to read it yet.
  2. There is JMeter EC2 script which you can utilize or use as a basic for your research, theoretically it should simplify deploying and configuring JMeter on Amazon.
  3. Don't run software as root unless you absolutely require it, it is kind of dangerous.
