API Call Counters

[humoflife]

What problem are you facing?

Crossplane users would like to know how many API calls to which APIs a provider makes. Please expose an API call counter metric at the provider metric interface.

There should be a roll up metric for all API calls, all API calls per API version, and a counter for each separate API/version. Those three categories could be satisfied through labels for the same metric. They would allow a quick view of overarching trend changes after updating or introducing new compositions, or additional claims. They would also inform about API version adoption, and provide an overview of which APIs are more popular and to which degree.

How could Official AWS Provider help solve your problem?

Implement and expose the following metrics at port 8080/metrics:

• api_call_count {group="...", version="...", kind="..."}

Moved this to crossplane/upjet#297 to that all providers that were generated with Upjet may benefit from the implementation. Closing this github issue in favor of the Upjet issue.
