JMeter - fail a test based on the average response time

Question

I am running a JMeter job in Jenkins using performance plugin. I need to fail a job if the average response time < 3 seconds. I see the \"duration assertion\" in jmeter, but

You can implement this check via some form of Beanshell scripting

1. Add a Beanshell Listener at the same level as all your requests live

2. Put the following code into Beanshell Listener's "Script" area

   String requests = vars.get("requests");
   String times = vars.get("times");
   long requestsSum = 0;
   long timesSum = 0;
   
   if (requests != null && times != null) {
       log.info("requests: " + requests);
       requestsSum = Long.parseLong(vars.get("requests"));
       timesSum = Long.parseLong(vars.get("times"));
   }
   
   long thisRequest = sampleResult.getTime();
   timesSum += thisRequest;
   requestsSum++;
   
   vars.put("requests", String.valueOf(requestsSum));
   vars.put("times", String.valueOf(timesSum));
   
   
   long average = timesSum / requestsSum;
   
   if (average > 3000){
       sampleResult.setSuccessful(false);
       sampleResult.setResponseMessage("Average response time is greater than threshold");
   }
   

   The code above will record sums of response times for each request and total number of requests into times and requests JMeter Variables
