getting response times using JSR223 + JMeter

Is it possible to get the actual response time of API requests made using the JSR223/groovy sampler in JMeter ? I have the following working code, but do not get proper response time when i watch my listeners (response content is actually fine, some json data).

The target URL is given in the 'parameter' field in the sampler (based on Dmitri's example). Furthermore i added a bearer token into header to use the OAuth access token when doing requests.

I did try to use a Transaction controller and include the JSR223 sampler within it, but this did not work in getting the response time (even not when creating a parent sample).

import org.apache.http.HttpEntity
import org.apache.http.HttpResponse
import org.apache.http.client.HttpClient
import org.apache.http.client.methods.HttpGet
import org.apache.http.impl.client.DefaultHttpClient
import org.apache.http.util.EntityUtils

import java.util.concurrent.ExecutorService
import java.util.concurrent.Executors

List<String> urls = new ArrayList<String>(); // initialize array of URLs
Collections.addAll(urls, args); // read URLs from "Parameters" input and add them to array
ExecutorService pool = Executors.newFixedThreadPool(urls.size());

// initialize pool of Future Tasks with number of threads equal to size of URLs provided
for (String url : urls) { // for each URL from list
    final String currentURL = url;
    pool.submit(new Runnable() { // Sumbit a new thread which will execute GET request

        @Override
        public void run() {
            try {
                HttpClient client = new DefaultHttpClient();                // Use Apache Commons HTTPClient to perform GET request
                HttpGet get = new HttpGet(currentURL);                      

                get.addHeader("authorization","Bearer ${AccessToken}");     // Add the access token into the header 
                get.addHeader("connection","keep-alive");                   // Add keep-alive in header

                HttpResponse response = client.execute(get);                // HttpResponse response = client.execute(post);
                HttpEntity entity = response.getEntity();
                log.info("Response Status Code: " + response.getStatusLine().getStatusCode() + " " + response.getStatusLine().getReasonPhrase());       
                SampleResult.setResponseData(EntityUtils.toByteArray(entity));        
            } catch (Exception ex) {
                ex.printStackTrace();
                throw ex;
            }

        }
    });
}
pool.shutdown(); // shut down thread pool

Your sample returns before the thread executing your request is finished, the shutdown() method of ThreadPoolExecutor initiates the shutdown but does not wait for it . Try with awaitTermination: pool.awaitTermination(60, TimeUnit.SECONDS)
