Azure NetApp Files provides metrics on allocated storage, actual storage usage, volume IOPS, and latency. By analyzing these metrics, you can gain a better understanding on the usage pattern and volume performance of your NetApp accounts.
1414

15+
## Definitions
16+
17+
Understanding the terminology related to performance and capacity in Azure NetApp Files is essential to understanding the metrics available:
18+
19+
- **Capacity pool**: A capacity pool is how capacity is billed in Azure NetApp Files. Capacity pools contain volume.
20+
- **Volume quota**: The amount of capacity provisioned to an Azure NetApp Files volume. Volume quota is directly tied to automatic Quality of Service (QoS), which impacts the volume performance. For more information, see [QoS types for capacity pools](azure-netapp-files-understand-storage-hierarchy.md#qos_types).
21+
- **Throughput**: The amount of data transmitted across the wire (read/write/other) between Azure NetApp Files and the client. Throughput in Azure NetApp Files is measured in bytes per second.
22+
- **Latency**: Latency is the amount of time for a storage operation to complete within storage from the time it arrives to the time it's processed and is ready to be sent back to the client. Latency in Azure NetApp Files is measured in milliseconds (ms).
23+
24+
## About storage performance operation metrics
25+
26+
An operation in Azure NetApp Files is defined as _something_ that happens during a client/server conversation. For instance, when a client requests a file to be read from Azure NetApp Files, read and other operations are sent and received between the client and server.
27+
28+
When monitoring the Azure NetApp Files volume, read and write operations are self-explanatory. Also included in the metrics is a metric called **Other IOPS**, meaning any operation that isn't a read or write. **Other IOPS** encompasses operations such as metadata, which is present alongside most read and write operations.
29+
30+
The following types of metadata operations are included in the **Other IOPS** metric:
31+
32+
**NFSv3**
33+
34+
NFSv3 metadata calls included in **Other IOPS** as covered in [RFC-1813](https://www.rfc-editor.org/rfc/rfc1813):

56+
57+
**NFSv4.1**
58+
59+
