Regarding O11 and its caching capabilities (cache in minutes property on aggregates and server actions) it would be useful to have some metrics that allows us to understand the cache misses/cache hits or even cache miss ratio so that we validate if the cache in minutes property is being used wisely.

The goal here is to catch the incorrect usage of cache in minutes, sometimes this feature is uses without doing the right assessment of data skewness and its usage. Sometimes the evolution and usage of the applications makes the business data to grow/change making the cache somehow less useful

Having a cache with 70% miss ratio means we are missing the cache 7 out of 10 times, meaning, we are wasting resources (in this particular case, cache should not be used)

Its hard to find which modules and core are using cache. Its hard to check the cache size. Providing this metric would allows development teams and CoE to have visibility on the cache usage and adapt
