I have a transaction controller and in that 5 requests are there. Now when i run a load test and in my script "Generate parent sampler" is checked. So here what is happening is whenever a failure occurs in any of the requests within this sampler, the transaction controller shows a message like "None" or "Number of sampler" etc.
I am using Grafana to monitor my test results, so how can i show the failed response message of a failed request to a transaction controller first and then show the message in grafana
