Getting desirable JMeter reports from java code

Question

Currently I'm struggling with getting desirable JMeter reports from java code. My goal is to get latency and throughput logged into file for each transaction and then have a summary per each scenario with averages and max/min values for latency and throughput.

Currently I have this code for reports:

ResultCollector csvlogger = new ResultCollector(summer);
csvlogger.setFilename(csvLogFile);
testPlanTree.add(testPlanTree.getArray()[0], csvlogger);

But in this way it logs info only per one transaction and there is no throughput, and latency reported is simply 0 (without any decimal part). It looks like this:

timeStamp,elapsed,label,responseCode,responseMessage,threadName,dataType,success,failureMessage,bytes,sentBytes,grpThreads,allThreads,Latency,IdleTime,Connect
2017/06/28 08:53:49.276,1014,Jedis Sampler,200,OK,Jedis Thread Group 1-1,text,true,,0,0,1,1,0,0,0

Does anyone know is there any way how I can tune it?

Thanks!

only per one transaction - .jtl log file contains execution of single sampler, try adding more threads and/or loops on Thread Group level and you should see more results.
Latency always zero for scripting-based samplers, you need to explicitly call SampleResult.setLatency() method and set the desired value.
Throughput is not being recorded, it is being calculated. You need to open .jtl results file with i.e. Aggregate Report or Summary Report listener to see the generated value. Take a look into org.apache.jmeter.util.Calculator class source to see the details if you prefer programmaticall non-GUI approaches.
