 Metrics that help diagnose disk IO capping:
 
-- **Data Disk IOPS Consumed Percentage**: The percentage calculated by the data disk IOPS completed over the provisioned data disk IOPS. If this amount is at 100%, your application running is IO capped from your data disk's IOPS limit.
-- **Data Disk Bandwidth Consumed Percentage**: The percentage calculated by the data disk throughput completed over the provisioned data disk throughput. If this amount is at 100%, your application running is IO capped from your data disk's bandwidth limit.
-- **OS Disk IOPS Consumed Percentage**: The percentage calculated by the OS disk IOPS completed over the provisioned OS disk IOPS. If this amount is at 100%, your application running is IO capped from your OS disk's IOPS limit.
-- **OS Disk Bandwidth Consumed Percentage**: The percentage calculated by the OS disk throughput completed over the provisioned OS disk throughput. If this amount is at 100%, your application running is IO capped from your OS disk's bandwidth limit.
+- **Data Disk IOPS Consumed Percentage**: The percentage calculated by dividing the actual data disk IOPS completed by the provisioned data disk IOPS. If this amount is at 100%, your application running is IO capped from your data disk's IOPS limit.
+- **Data Disk Bandwidth Consumed Percentage**: The percentage calculated by dividing the actual data disk throughput completed by the provisioned data disk throughput. If this amount is at 100%, your application running is IO capped from your data disk's bandwidth limit.
+- **OS Disk IOPS Consumed Percentage**: The percentage calculated by dividing the actual OS disk IOPS completed  by the provisioned OS disk IOPS. If this amount is at 100%, your application running is IO capped from your OS disk's IOPS limit.
+- **OS Disk Bandwidth Consumed Percentage**: The percentage calculated by dividing the actual OS disk throughput completed by the provisioned OS disk throughput. If this amount is at 100%, your application running is IO capped from your OS disk's bandwidth limit.
 
 Metrics that help diagnose VM IO capping:
 
-- **VM Cached IOPS Consumed Percentage**: The percentage calculated by the total IOPS completed over the max cached virtual machine IOPS limit. If this amount is at 100%, your application running is IO capped from your VM's cached IOPS limit.
-- **VM Cached Bandwidth Consumed Percentage**: The percentage calculated by the total disk throughput completed over the max cached virtual machine throughput. If this amount is at 100%, your application running is IO capped from your VM's cached bandwidth limit.
-- **VM uncached IOPS Consumed Percentage**: The percentage calculated by the total IOPS on a virtual machine completed over the max uncached  virtual machine IOPS limit. If this amount is at 100%, your application running is IO capped from your VM's uncached IOPS limit.
-- **VM Uncached Bandwidth Consumed Percentage**: The percentage calculated by the total disk throughput on a virtual machine completed over the max provisioned virtual machine throughput. If this amount is at 100%, your application running is IO capped from your VM's uncached bandwidth limit.
+- **VM Cached IOPS Consumed Percentage**: The percentage calculated by dividing the total actual cached IOPS completed by the max cached virtual machine IOPS limit. If this amount is at 100%, your application running is IO capped from your VM's cached IOPS limit.
+- **VM Cached Bandwidth Consumed Percentage**: The percentage calculated by dividing the total actual cached  throughput completed by the max cached virtual machine throughput. If this amount is at 100%, your application running is IO capped from your VM's cached bandwidth limit.
+- **VM uncached IOPS Consumed Percentage**: The percentage calculated by dividing the total actual uncached IOPS on a virtual machine completed by the max uncached  virtual machine IOPS limit. If this amount is at 100%, your application running is IO capped from your VM's uncached IOPS limit.
+- **VM Uncached Bandwidth Consumed Percentage**: The percentage calculated by dividing the total actual uncached throughput on a virtual machine completed over the max provisioned virtual machine throughput. If this amount is at 100%, your application running is IO capped from your VM's uncached bandwidth limit.
