Hi.. Can you please explain the meaning of this in the analytics section in Azure APIM Please help me understand all 4 terms

@Abhay Chandramouli Thanks for reaching out. there are two types of caching that APIM supports, response caching and value caching. Response cache caches responses returned by the backend from the forward-request policy. Value caching allows customer to store name-value pairs in the cache. Cache Hit/response cache hit : this metric shows how many times your API requests have been able to find the expected response in the internal cache for your APIM instance. Cache Miss/response cache Miss : this metric shows how many times your API requests did not find a response in the internal cache for your APIM instance. value cache hit count : this metric shows the number of times that APIM found a cached value for a request in the value cache. value cache miss count : this metric shows the number of times that APIM did not find a cached value for a request in the value cache. do let me know incase of further queries, I would be happy to assist you.

Hi @JananiRamesh-MSFT ,

is value caching the "Named values" which are cached every request or the explicit cache we store via code using https://learn.microsoft.com/en-us/azure/api-management/cache-store-value-policy ? Or count of both ?

Abhay Chandramouli Value caching in APIM refers to the cache that you store via code using the cache-store-value policy. This allows you to store name-value pairs in the cache, which can be useful for storing frequently accessed data that does not change frequently, such as configuration settings or reference data.

The Named values feature in APIM is a separate feature that allows you to store configuration settings that can be used across multiple APIs and operations. Named values are not cached every request, but rather are loaded into memory when the API is loaded and are available for use by any operation in the API.

The value cache hit count and value cache miss count metrics in APIM specifically refer to the explicit cache that you store via code using the cache-store-value policy. These metrics do not include the Named values feature.

hope this helps! do let me know incase of further queries, I would be happy to assist you.
