Use Post‑Execution Scripts in Dynatrace Synthetic HTTP Monitors

Summary: This post explains how post‑execution scripts work in Dynatrace synthetic HTTP monitors. It provides instructions on where to define the script, what data can be accessed, and supported use cases.

Hello everyone,

I'm encountering an issue with my Synthetic HTTP post-execution script and could use some help troubleshooting.

I have the following script where I define the responseBody directly within the code:

var responseBody = { "db": [ { "status": "UP", "details": { "db_name": "apig_otk", "jdbc_name": "OAuth", "metric_name": "count otk_sessionstore", "metric_value": 61956, "threshold": 2000000 } }, { "status": "UP", "details": { "db_name": "apig_ssg", "jdbc_name": "SSG", "metric_name": "count ssg_certificates", "metric_value": 378, "threshold": 490 } }, { "status": "DOWN", "details": { "db_name": "sm_SessionStore", "jdbc_name": "SM_SessionStore", "metric_name": "count sm_sessionspec5", "metric_value": 79, "threshold": 1000 } }, { "status": "UP", "details": { "db_name": "sm_SessionStore", "jdbc_name": "SM_SessionStore", "metric_name": "count sm_sessionvar5", "metric_value": 155, "threshold": 2000 } } ] };

With the above, the script works as expected, and I receive a failure message if the status is DOWN.

However, when I modify the script to dynamically retrieve the responseBody using the following lines:

//var responseBody = response.getResponseBody() //var obj = JSON.parse(responseBody);

And replace the direct reference to responseBody with the parsed object obj, the script doesn't seem to generate any output. No failure message appears, and I can't figure out what's going wrong.

Here's what I'm trying:

But this doesn't seem to be working. I don't get any failure message, and I’m unable to determine the root cause. Has anyone encountered this issue before, or can anyone point me in the right direction to fix it?

Thank you for any help!

Sofia

Hello @SofiaPersia

Below is a short script snippet you can copy and paste into your HTTP monitor’s post-execution script. It will help you quickly pinpoint whether there’s an issue with an empty response body, invalid JSON, or a missing db array. Just replace any relevant variable names as needed:

This should help you identify where the script might be failing:

Empty body if nothing is returned.
Parsing errors if the response isn’t valid JSON.
Missing structure if db isn’t present or isn’t an array.

From there, you can add your logic to check status === "DOWN" and report accordingly. Good luck!
