Question

Azure APIM Internal cache - Identify cache memory used

Anonymous

Is there a way to find how much cache memory utilized in Azure APIM ? By this I need to further decide on increasing the size or opting for external cache. As of now I can find only cache hit, miss counts not the exact cache memory usage.

Hi @Anonymous Thanks for reaching out. The stated ask doesn’t seem to be directly possible since cache usage metrics are currently not emitted by default for APIM services.

I also came across this feature request raised on the Azure Feedback Forum where it had a similar ask -

Hi @Anonymous

Thanks for reaching Q & A forum.

APIs and operations in API Management can be configured with response caching. Response caching can significantly reduce latency for API callers and backend load for API providers.

Internal cache is not available in the Consumption tier of Azure API Management. You can use an external Azure Cache for Redis instead.

Add the caching policies

Hi @SUNOJ KUMAR YELURU , we have Premium tier and Response cache is enabled. Goal is to find cache memory utilization graph out of 5GB allocated.

APIM Analytics shows cache hit and miss counts but not the memory heap graph
