View the capacity monitoring data of a General-purpose NAS file system - Apsara File Storage NAS

Apsara File Storage NAS (NAS) is seamlessly integrated with CloudMonitor. The capacity monitoring feature allows you to view the following information in real time: the data volume of General-purpose NAS file systems, the data volume of the IA storage class, the read and write traffic of the IA storage class, and the number of files. This topic describes how to view the capacity monitoring data of a General-purpose NAS file system.

Prerequisites

A NAS file system is created. For more information, see Create a file system.
CloudMonitor is activated.
To activate CloudMonitor, go to the product page of CloudMonitor and follow the instructions.

View the capacity monitoring 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, perform the following steps to view the capacity monitoring data of the file system:
1. Select the type of the file system from the File System Type drop-down list.
2. Select the ID of the file system from the File System ID drop-down list.
3. Specify a time range. You can select 1 Hour, 1 Day, 7 Days, 14 Days, Current Month, or Last Month. You can also select a start time and an end time to specify a custom time range. The time range cannot exceed 30 days. For information about how to view the capacity monitoring data of more than one month, see Query the usage details of file systems.
For General-purpose NAS file systems, the Capacity Monitoring page displays the monitoring data in charts based on the following metrics: storage space (excluding the recycle bin), number of files, read traffic of the IA storage class, and write traffic of the IA storage class.
Note
Capacity monitoring data is generated in real time and may not be the same as the usage data recorded in your bills. For information about how to view the billing and usage details of a file system, see View billing and usage details.

View the capacity monitoring data in the CloudMonitor console

Log on to the CloudMonitor console.
In the left-side navigation pane, choose Cloud Service Monitoring > Cloud Service Monitoring.
On the Cloud Service Monitoring page, enter NAS in the search box and click NAS.
On the Apsara File Storage NAS (NAS) page, select a region. On the Apsara File Storage NAS (NAS) tab, click the file system ID or click Monitoring Charts in the Actions column.
On the page that appears, click the File System Capacity tab. View the capacity data of the file system in the monitoring charts.
By default, CloudMonitor displays the monitoring data of the last hour. You can select a preset time range or specify a custom time range. The time range cannot exceed 30 days. For information about how to view the capacity monitoring data of more than one month, see Query the usage details of file systems.
Note
Capacity monitoring data is generated in real time and may not be the same as the usage data recorded in your bills. For information about how to view the billing and usage details of a file system, see View billing and usage details.

View the capacity monitoring data by calling CloudMonitor API operations

You can call the following CloudMonitor API operations to query the capacity monitoring data of a NAS file system:

DescribeMetricMetaList: queries the details of time series metrics that are supported by CloudMonitor.
DescribeMetricList: queries the monitoring data of a metric for a specified cloud service.
DescribeMetricLast: queries the latest monitoring data of a metric.

The following table describes the request parameters that you must configure to query the monitoring data of a NAS file system.
