Custom Attribute Retrieval in VMware App (Add-on for VMware Metrics)

Assistance with Custom Attribute Retrieval in VMware App for Splunk
Hello everyone,
I'm currently working on integrating custom attributes from VMware into Splunk ITSI using the Splunk Add-on for VMware Metrics.
The standard functionality of the add-on doesn't seem to support custom attribute retrieval out-of-the-box and I need a "TechnicalService" custom attribute for an entity split.

To tackle this, I am looking into extending the existing add-on scripts, particularly focusing on the CustomFieldsManager within the VMware API.

I've explored the inventory_handlers.py, inventory.py, and mo.py scripts within the add-on and found a potential pathway through the CustomFieldsManager class in mo.py.
However, I'd appreciate any insights or guidance from those who have tackled similar integrations or extensions.

Specifically, I'm interested in:

Best practices for extending the add-on to include custom attributes without affecting its core functionalities.
Any known challenges or pitfalls in modifying these scripts for custom attribute integration.
Advice on testing and validation to ensure stable and efficient operation post-modification.

I'm open to suggestions, alternative approaches, or any resources that might be helpful in this context.

Thank you in advance for your assistance and insights!
kind regards,
Charly
