View data in the NAS console

Log on to the NAS console.
In the left-side navigation pane, choose Monitoring Audit > Capacity Monitoring.
In the top navigation bar, select a region.
On the Capacity Monitoring page, do the following to view capacity monitoring details for a CPFS file system:
1. From the File System Type drop-down list, select CPFS.
2. Select the ID of the file system from the File System ID drop-down list.
3. Select a time range. You can select 1 Hour, 1 Day, 7 Day, 14 Days, Current Month, or Last Month. You can also specify a custom time range. The time range cannot exceed 30 days. To view data for a period longer than 30 days, see View billing and usage data.
The Capacity Monitoring page displays charts for two main categories: Storage Space and Number of Files.
- Storage Space: includes metrics for total storage space and used space.
- Number of Files: Includes metrics for the maximum number of files, allocated files, used files, files allocated to filesets, files used by filesets, files allocated to the root fileset, and files used by the root fileset.
Note
The root fileset is the default fileset of a file system. It contains all files that do not belong to any independently created filesets.

For more information about the metrics, see Metrics.

View data in the CloudMonitor console

Log on to the CloudMonitor console.
In the navigation pane, choose Cloud Service Monitoring.

View data by using the CloudMonitor API

You can also query CPFS monitoring data by calling CloudMonitor API operations. Key API operations include:

DescribeMetricMetaList: queries the descriptions of available time-series metrics in CloudMonitor.
DescribeMetricList: queries the monitoring data of a time-series metric for an Alibaba Cloud service within a specified time period.
DescribeMetricLast: queries the latest monitoring data of a specified monitored object.

The following table describes the request parameters for CPFS.

Parameter	Description
Namespace	The namespace of the cloud service. For CPFS, the namespace is `acs_nas`.
MetricName	The name of the metric. Valid values: File system instance CPFSCapacity CPFSCapacityUsed CPFSInodeLimit CPFSInodeAlloc CPFSInodeUsed fileset FsetInodeUsed FsetInodeAlloc
Dimensions	A map of dimensions for querying monitoring data from a specific resource. The format is as follows: `{"userId":"xxxxxx","fileSystemId":"cpfs-xxxxx","fSet:xxxxx"}`. Note The Dimensions parameter must be passed as a JSON string, and the key-value pairs must be in the specified order.

You can configure an alert rule to receive prompt notifications about abnormal data. This allows you to respond to exceptions and restore services quickly. For more information, see Configure a basic alert rule.
You can also create an application group for multiple file systems to manage alert rules and view monitoring data at the group level. This simplifies management and improves monitoring efficiency. For more information, see Create an application group.
