Automatically scaled to maximum throughout for Cosmos DB

[tomkerkhove]

Usecase scenario

Automatically create awareness when the Cosmos DB Autoscaler has scaled to the maximum capacity scaling by posting in Teams, paging a human, automating processes, etc.

This is important so that other components could be scaled down to avoid flooding Cosmos DB even more (ie background processing, batch jobs, etc) or to trigger custom automation to adjust the configured autoscaler accordingly.

The event should provide information amount new and previous provisioned RUs as well as what the maximum is and the scale target (database and or collection).

While there is no metric for this as well, Azure Event Grid events are different from metrics, and other techniques, such as being real time and having contextual information so that would not cover it.
