-For example, if an automatic QoS volume in the Premium storage tier has only 500 GiB of data but requires 128 MiB/s of throughput, you can set the quota to 2 TiB so that the throughput level is set accordingly (64 MiB/s per TB * 2 TiB = 128 MiB/s).

 If you use manual QoS volumes, you don’t have to overprovision the volume quota to achieve a higher throughput because the throughput can be assigned to each volume independently. However, you still need to ensure that the capacity pool is pre-provisioned with sufficient throughput for your performance needs. The throughput of a capacity pool is provisioned according to its size and service level. See [Service levels for Azure NetApp Files](azure-netapp-files-service-levels.md) for more details.
 
+## Monitoring volumes for performance 
+
+Azure NetApp Files volumes can be monitored using available [Performance metrics](azure-netapp-files-metrics.md#performance-metrics-for-volumes). 
+
+When volume throughput reaches its maximum (as determined by the QoS setting), the volume response times (latency) increase. This effect can be incorrectly perceived as a performance issue caused by the storage. Increasing the volume QoS setting (manual QoS) or increasing  the volume size (auto QoS) increases the allowable volume throughput. 
+
+To check if the maximum throughput limit has been reached, monitor the metric [Throughput limit reached](azure-netapp-files-metrics.md#volumes). For more recommendations, see [Performance FAQs for Azure NetApp Files](faq-performance.md#what-should-i-do-to-optimize-or-tune-azure-netapp-files-performance).
