JSON Response - limit search top 20lines only- HTTP Monitor script


We have a swagger API which outputs a JSON response that has status detail about the execution of our batchjob. 


In my post execution script of HTTPMonitor of Dynatrace synthetics, I have this logic


responseObject = JSON.parse(response.getResponseBody());

responseObject.runs.forEach(x => {

    if (x.success != true) { + " failed");




Batch jobs runs once a day. Our swagger JSON response has status details of last 50executions in the JSON body. I'm only interested in the 0 response - which has the status info of basically today's execution & ignore all the rest.  The above logic works when last 50th execution has no "success :fail" in them 


Anyone knows how to limit the search in post execution script of an HTTP Monitor to only look for 0 iteration,  or ,  search first 20lines only & ignore rest of the JSON payload, and if you find "success :true" that means batch job ran successfully. Because first 20 lines has the last execution detail in it..





You can parse the response body as json. I guess you'd want something like:

var responseBody = response.getResponseBody();
var jsonData = JSON.parse(responseBody);
var ps=jsonData.runs[0].success;
