Read .PEM files and add data in Dynatrace

bhushansoni — Tue, 09 Dec 2025 13:13:44 GMT

Hi, we have some .PEM certs that Dynatrace doesn't identify using SSL cert extension, as these certs are not running on any domain or port.

So we want to read all details from these certs and add the result in Dynatrace.

I created a python scripts and added result in excel, but I want to do it in automated way using Dynatrace extension.

Please let us know how to achieve that.

Thank you

Hello @bhushansoni

Since you already have a Python script parsing .pem files, you can turn that into a Dynatrace Extension 2.0 (Python). At a high level, the steps are: install the Dynatrace Extensions SDK, define an activation schema, implement the logic in __main__.py, then build and upload the extension.
However, this process can be a bit complex. In one of my client projects, I followed another approach:

Ran the Python script externally. Pushed the parsed certificate data into Dynatrace using the Metrics v2 API (or OpenPipeline for richer data). Finally, created dashboards and alerts based on the ingested metrics.

Yes, that’s definitely the best approach. In my case, the requirement was for a lower environment, so I opted for the external script method to avoid adding extra overhead on the ActiveGate and keep things lightweight. For production or long-term automation, building an Extension is the right choice because it ensures native integration, better maintainability, and avoids manual intervention
