APIM Basic SKU base Capacity metrics very high
A vanilla new APIM Basic SKU capacity meter can show utilization over 30% of it's capacity and CPU with no requests being routed through it.
This is not occurring to Developer or Standard SKUs.
I expect same behavior as other SKUs.
Azure support is unable to tell what in background churns APIM resources.
This becomes particularly critical as you start routing production traffic through and something may suddenly take 30+% of your capacity.
