View the performance monitoring data of a CPFS file system - Cloud Parallel File Storage

The performance monitoring feature of Cloud Parallel File Storage (CPFS) allows you to view the performance details of a file system in real time, such as read/write IOPS and read/write throughput. This topic describes how to view the performance monitoring data of a CPFS file system.

Prerequisites

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

View the performance monitoring data in the NAS console

Log on to the NAS console.
In the left-side navigation pane, choose Monitoring Audit > Performance Monitoring.
In the top navigation bar, select a region.
On the Performance Monitoring page, perform the following steps to view the performance monitoring details of a specific file system:
1. Select CPFS for Lingjun 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. Select a time range. Valid values: 1 Hour, 1 Day, 7 Days, 14 Days, Current Month, and Last Month. Alternatively, specify a custom time range.
The Performance Monitoring page displays the charts of the IOPS and throughput metrics.

View the performance 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 CPFS in the search box, and then click Cloud Parallel File Storage (CPFS).
On the Cloud Parallel File Storage (CPFS) page, select a region and click Monitoring Charts in the Actions column.
On the details page of the monitoring charts, click the File System Monitoring tab to view the performance monitoring details of the file system.

View the performance monitoring data by calling CloudMonitor API operations

You can call CloudMonitor API operations to query the metrics of the CPFS file system. The following API operations are available:

DescribeMetricMetaList: queries the details of metrics that are supported in CloudMonitor.
DescribeMetricList: queries the monitoring data of a metric for a specific cloud service.
DescribeMetricLast: queries the latest monitoring data of a metric.

The following table lists the request parameters for the CPFS file system.

Parameter	Description
Namespace	The namespace of the cloud service. The value is acs_nas for CPFS.
MetricName	The metric name. Valid values: IopsRead IopsWrite ThruputRead ThruputWrite
Dimensions	The dimensions that specify the resources whose monitoring data you want to query. Format: `{"userId":"xxxxxx","fileSystemId":"xxxxx"}`. Note Dimensions must be formatted as a JSON string in a specific order.
Dimensions	The dimensions that specify the resources whose monitoring data you want to query. Format: `{"userId":"xxxxxx","fileSystemId":"bmcpfs-xxxxx"}` Note Dimensions must be formatted as a JSON string in a specific order.

What to do next

You can configure alert rules to obtain information about exceptions at the earliest opportunity. If an exception occurs, the technical support personnel can process the exception to resume business at the earliest opportunity. For more information, see Configure a basic alert rule.
You can create groups to categorize multiple file systems. Then, you can manage alert rules and view monitoring data based on the groups. This reduces the management complexity and improves the monitoring efficiency. For more information, see Create an application group.
