 Azure NetApp Files provides metrics on allocated storage, actual storage usage, volume I/OPS, and latency. Use these metrics to understand usage and performance.

+- *Percentage Volume Consumed Size*

     The percentage of the volume consumed, including snapshots.  
     Aggregation metrics (for example, min, max) aren't supported for percentage volume consumed size.
-- *Volume Allocated Size*   
+- *Volume Allocated Size*

 - *Volume Quota Size*    
+
     The quota size (GiB) the volume is provisioned with.   
 - *Volume Consumed Size*   
+
     Logical size of the volume (used bytes).  
     This size includes logical space used by active file systems and snapshots.  
 - *Volume Snapshot Size*   
+ 
    The size of all snapshots in a volume.  
+- *Volume Inodes Quota*
+    
+    The volume's maximum allowed [inodes (or `maxfiles`)](maxfiles-concept.md) if the limit was increased via support request. If the limit hasn't been increased via support request, this metric's value is 0.
+
+- *Volume Inodes Total*
+
+    The volume's maximum allowed [inodes (or `maxfiles`)](maxfiles-concept.md) based on the volume size.
+- *Volume Inodes Used*
+
+    The volume's used [inodes (or `maxfiles`)](maxfiles-concept.md).

 - *Volume Inodes Percentage* 
 
-    The percentage of the volume's available [inodes (or `maxfiles`)](maxfiles-concept.md) consumed. 
+    The percentage of the volume's available [inodes (or `maxfiles`)](maxfiles-concept.md) consumed.
+
+    If the volume inode limit has been increased by a support request, the percentage is calculated based on Volume Inodes Quota metric. If the volume inode limit is the default value based on the volume size, the percentage is calculated based on the Volume Inodes Total metric.

+
+    Azure NetApp Files supports [new metrics](azure-netapp-files-metrics.md#volumes) to monitor consumption of [inodes (also known as maxfiles)](maxfiles-concept.md), which is the maximum number of files a volume can hold. These metrics are especially useful for workloads with high file counts, such as high-performance compute (HPC) or electronic design automation (EDA), where you might have millions of small files. By monitoring these metrics, you can avoid running out of inodes thus keeping your storage running smoothly and making it easier to plan for future needs.

 * [File access logs](manage-file-access-logs.md) (preview)
 
     File Access Logs provides detailed logging of file access activities, including user identity, operation type, and timestamps, enhancing security, reliability, and operational insights. It supports SMB, NFSv4.1, and dual-protocol volumes, offering valuable features for monitoring unauthorized access, tracing activity for compliance, resolving incidents, and optimizing data usage patterns. By embedding this capability, you can strengthen your organization's security posture, maintain system reliability, and achieve operational excellence in alignment with the Well-Architected Framework security best practices. Azure NetApp Files file access logs play a critical role in safeguarding sensitive data, detecting anomalies while enabling operational excellence.
