+## What
+
+Emit MCAD custom metrics such as total allocatable CPU, GPU and memory.
+
+## Why
+
+MCAD custom metrics information is important for enabling generation of an overall up-to-date observablity view of the running app wrappers and connecting to other stack layers.
+This will align MCAD with other existing components in OCP that expose metrics in Prometheus format and allow the collection and building of cross-component context.
+
+## Goals
+
+* Emit MCAD custom metrics 
+
+## Non-Goals
+
+The following are not included in this ADR:
+* Emit metrics of other components
+* Connect MCAD metrics to metrics of other components
+
+## How
+
+Register collected metrics with the runtime controller of the CodeFlare Operator. The metrics will be exposed in standard Prometheus format.
+
+
+## Alternatives
+
+Given the CodeFlare operator re-design that enables off-the-shelf exposure of metrics, we have not currently considered any alternatives.
+Currently, the MCAD dashboard relies on external components to report the information and there is no guaranty that what MCAD is using aligns to that information.
