Configuring an Alarm Rule for the Disk Usage of All Mount Points on an ECS

Scenarios

Cloud Eye allows you to configure alarm rules for all mount points of an ECS. This section describes how to configure alarm rules for the disk usage of all mount points on an ECS.

• The mount point dimension is added to metric disk usage. When you configure a new alarm rule for the disk usage, you need to select the ECS - Mount Point dimension.
• If you have configured an alarm rule for Any mount point of an ECS, the alarm rule will automatically apply to new mount points of the ECS.
• If you have configured an alarm rule for the disk usage of the mount point, when you modify the alarm rule, the system prompts you to split the alarm rule into multiple rules in different dimensions. You are advised to select all mount points for the new alarm rules.
