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

Through the performance monitoring feature, you can view the performance overview of read and write IOPS, read and write throughput, and other metrics of file systems or data flows in real-time. This topic describes how to view the performance monitoring data of a CPFS intelligent file system.

Prerequisites

CloudMonitor is activated.
You can log on to the CloudMonitor product page and follow the instructions on the page to activate the service.
A NAS file system is created. For more information, see Create a NAS file system.

Use the file storage 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 operations to view the performance monitoring details of the specified file system.
1. In the File System Type drop-down list, select CPFS Intelligent Edition.
2. Select the ID of the file system from the File System ID drop-down list.
3. Select the query time (1hour Hour, 1day Day, 7 Days, 14 Days,Current Month, Last Month) or select the desired date range in the custom time box. The time range cannot exceed 30 days.
4. Select the All or Data Flow tab to view the performance of the file system or the import and export tasks of data flows.

Use the CloudMonitor console

Log on to the CloudMonitor console.
In the left navigation bar, select Cloud Resource Monitoring > Cloud Service Monitoring.
On the Cloud Service Monitoring page, enter CPFS and click Cloud Parallel File Storage.
On the Cloud Parallel File Storage page, select a region and click the Operation column of the target file system to view the Monitoring Chart.
On the Monitoring Chart details page, select the File System Monitoring tab to view the monitoring details of the target file system.

Use the CloudMonitor API

The monitoring data of CPFS can also be queried through the CloudMonitor API. The main APIs are as follows.

DescribeMetricMetaList: Queries the description of time-series metric items opened by CloudMonitor.
DescribeMetricList: Queries the time-series metric monitoring data of cloud services within a specified time range.
DescribeMetricLast: Queries the latest monitoring data of a specified monitored object.

The request parameters of CPFS are described in the following table.

You can configure alert rules to obtain information about exceptions in a timely manner. If an exception occurs, the technical support personnel can process the exception to resume business at the earliest opportunity. For more information, see Configure basic alert rules.
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 application groups.
