The goal is to collect product usage data from local gateways to inform decision-making.
GDPR compliance needs to be considered when determining what data can be collected and stored.
A log/table should include events such as subscription start/stop and API methods called.
Each event should be logged with a timestamp and relevant parameters.
For streams, subscription/unsubscription and values should be included.
For API endpoints, parameters should be included.
Real-time data collection is ideal, but periodic collection is acceptable.
The data structure should be easily consumable, sortable, and analyzable.
Information on the gateway/user is to be determined based on GDPR compliance decisions.
The purpose of collecting this data is to make data-informed decisions about the product roadmap and priorities.
