 Azure offers metrics in the Azure portal that provide insight on how your virtual machines (VM) and disks perform. The metrics can also be retrieved through an API call. This article is broken into 3 subsections:
 
-- **Disk IO, throughput and queue depth metrics** - These metrics allow you to see the storage performance from the perspective of a disk and a virtual machine.
+- **Disk IO, throughput, queue depth and latency metrics** - These metrics allow you to see the storage performance from the perspective of a disk and a virtual machine.
 - **Disk bursting metrics** - These are the metrics provide observability into our [bursting](disk-bursting.md) feature on our premium disks.
 - **Storage IO utilization metrics** - These metrics help diagnose bottlenecks in your storage performance with disks. 
 
 All metrics are emitted every minute, except for the bursting credit percentage metric, which is emitted every 5 minutes.

+## Disk IO, throughput, queue depth and latency metrics
+The following metrics are available to get insight on VM and disk IO, throughput, and queue depth performance:
 
+- **OS Disk Latency (Preview)**: The average time to complete IOs during the monitoring for the OS disk. Values are in miliseconds.
 - **OS Disk Queue Depth**: The number of current outstanding IO requests that are waiting to be read from or written to the OS disk.
 - **OS Disk Read Bytes/Sec**: The number of bytes that are read in a second from the OS disk. If Read-only or Read/write [disk caching](premium-storage-performance.md#disk-caching) is enabled, this metric is inclusive of bytes read from the cache.
 - **OS Disk Read Operations/Sec**: The number of input operations that are read in a second from the OS disk. If Read-only or Read/write [disk caching](premium-storage-performance.md#disk-caching) is enabled, this metric is inclusive of IOPs read from the cache.
 - **OS Disk Write Bytes/Sec**: The number of bytes that are written in a second from the OS disk.
 - **OS Disk Write Operations/Sec**: The number of output operations that are written in a second from the OS disk.
+- **Data Disk Latency (Preview)**: The average time to complete IOs during the monitoring for the data disk. Values are in miliseconds.
 - **Data Disk Queue Depth**: The number of current outstanding IO requests that are waiting to be read from or written to the data disk(s).
 - **Data Disk Read Bytes/Sec**: The number of bytes that are read in a second from the data disk(s). If Read-only or Read/write [disk caching](premium-storage-performance.md#disk-caching) is enabled, this metric is inclusive of bytes read from the cache.

 ## Bursting metrics
 The following metrics help with observability into our [bursting](disk-bursting.md) feature on our premium disks:
