Spike: research whether current MLA stack and its data is capable of resource monitoring

- What information do we already store?
- What else do we need to collect?
- Do we need to get any data from providers? If yes, let's check one provider for first time.

No files, tests, or entry points are named. Inventory what the current MLA stack already stores, identify the additional resource data needed, and assess one provider for possible data collection; done means a documented feasibility result and collection requirements.
