Cloud Parallel File Storage (CPFS) General-purpose Edition integrates with CloudMonitor to track file system capacity, read/write throughput, and IOPS. Configure alert rules to receive notifications when metrics exceed specified thresholds.
Background
CloudMonitor monitors Alibaba Cloud resources and internet applications. You can track resource metrics, configure alert rules, and maintain application availability. For more information, see What is CloudMonitor?
Retention policy of monitoring data
Monitoring data is retained for 90 days from the time it is generated and then automatically cleared.
Metrics
CPFS integrates with CloudMonitor to monitor file system capacity, performance, and NFS protocol services.
Capacity monitoring
-
Capacity monitoring requires CPFS General-purpose Edition V2.3.1 or later. To check the version, go to the NAS console, open the File Systems page, and click the target CPFS General-purpose Edition file system name to view its version on the Basic Information page.
-
The root fileset is the root directory of the file system. All files that are not in independently created filesets belong to the root fileset.

Alert rules
You can configure alert rules for metrics in the CloudMonitor console. When a metric value meets an alert condition, CloudMonitor sends notifications to the specified recipients. The following table describes the alert severity levels, notification methods, and conditions.

Phone call, Short Message Service (SMS) message, Email, and DingTalk chatbot |
An alert triggers when the average metric value reaches the specified threshold for N consecutive cycles. Set N based on the alert severity. Note
Alert conditions vary by metric type. Refer to the console for details. |
