Review Comment:
   ```
     - name: memory_usage
       exp: redis_memory_used_bytes * 100 / redis_memory_max_bytes
     - name: memory_max_bytes
       exp: redis_memory_max_bytes
   ```
   These metrics are from the instances, right? Should sum for Service?

Review Comment:
   The result structure changed, and I think that's why the e2e failed. Can
