   Parameter	Description
   Alert Rule	Specify a subrule name.
   Metric Type	Select a metric type. Valid values: Single Metric: Select a metric and set the threshold and alert level for the metric. Multiple Metrics: Select an alert level and specify alert conditions for two or more metrics. Dynamic Threshold: For more information about dynamic thresholds, see Overview and Create dynamic threshold-triggered alert rules. Note The dynamic threshold feature is in invitational preview. To use the feature, you must submit a ticket.
   Metric	Select one or more metrics that you want to monitor. Valid values: gateway cpu usage user gateway memory usage file gateway share cache usage file gateway share meta data usage file gateway NFS connection usage file gateway share read write rate file gateway share throttling status upload queue file gateway share upload rate block gateway volume cache usage
   Select Dimension	Select the share that you want to monitor. If you do not select a share, all shares of the gateway are monitored.
   Comparison	The comparison type. When the metric value and the threshold meet the comparison condition, the alert is triggered. Valid values: >=: The alert is triggered if the metric value is greater than or equal to the threshold. >: The alert is triggered if the metric value is greater than the threshold. <=: The alert is triggered if the metric value is less than or equal to the threshold. <: The alert is triggered if the metric value is less than the threshold. =: The alert is triggered if the metric value is equal to the threshold. !=: The alert is triggered if the metric value is not equal to the threshold. Compared with Yesterday Rise: The alert is triggered if the metric value for a particular period of time is greater than the metric value for the same period of time yesterday. Compared with Yesterday Decline: The alert is triggered if the metric value for a particular period of time is less than the metric value for the same period of time yesterday. Compared with Last Week Rise: The alert is triggered if the metric value for a particular period of time is greater than the metric value for the same period of time last week. Compared with Last Week Decline: The alert is triggered if the metric value for a particular period of time is less than the metric value for the same period of time last week. Compared with Last Period Rise: The alert is triggered if the metric value increases compared with the last period of time. Compared with Last Period Decline: The alert is triggered if the metric value declines compared with the last period of time.
   Threshold and Alert Level	Configure the thresholds and alert levels.

Alert rule example

This section describes how to create an alert rule that sends an alert if the metadata usage is greater than or equal to 90%.

1. On the Cloud Service Monitoring Dashboards tab, click Create Alert Rule.

2. In the Create Alert Rule panel, select Cloud Storage Gateway for Product.

3. For Resource Range, select Instances.

4. For Associated Resources, select the gateway that you want to monitor.

5. Click Add Rule to go to the Configure Rule Description panel.

6. In the Configure Rule Description panel, perform the following steps: In the Alert Rule field, specify a name for the subrule. For Metric Type, select Single Metric. For Metric, select file gateway share meta data usage. In the Select Dimension section, select the share that you want to monitor from the share drop-down list. In the Threshold and Alert Level section, select Critical as the alert level, and enter 90 in the Threshold text bod. Click OK to return to the Create Alert Rule panel.

7. In the Create Alert Rule panel, select an alert contact group from the Alert Contact Group drop-down list and click Confirm.
