   Parameter	Description
   Alert name	The name of the alert rule. Example: JVM GC count period-over-period alert.
   Application	The application to which the alert rule applies.
   Metric type	The type of metric to monitor. For more information, see Alert rule metrics. Note The fields for the alert condition and filter condition vary depending on the selected metric type.
   Alert triggering rule	Meet all the following rules: The alert is triggered only if all alert conditions are met. Meet one of the following rules: The alert is triggered if any alert condition is met.
   Alert condition	Click +Add Condition to define the expression for an alert condition. Example: The average number of JVM Full GCs in the last 5 minutes increases by 100% compared to the previous hour. Then, click the icon on the right. Note Click the preview icon on the right side of a condition to preview the metric trend chart for the application under the current condition. Click the delete icon on the right side of a condition to delete its expression. To add multiple conditions to the alert rule, click +Add Condition again.
   Filter condition	Filter the metric to narrow the monitoring scope. Dimensions of the alert metric: Traverse: The alert notification includes the specific dimension value that triggered the alert. None: The alert notification includes the sum of all values for this dimension. =: The alert includes only data for the specified dimension value. !=: The alert includes data for all dimension values except the specified one. Contains: The alert includes only data for dimension values that contain the specified string. Does not contain: The alert includes data for all dimension values except those containing the specified string. RegEx match: The alert includes data only for dimension values that match the specified regular expression.
   Alert Condition	The severity of the alert. The levels, in ascending order of severity, are P4, P3, P2, and P1.
   Notification policy	Do not specify a notification rule: No notification is sent when this alert is triggered. Instead, notifications are sent only if the alert matches a dispatch rule in a notification policy. Specify a notification rule: When an alert is triggered, ARMS sends a notification based on the method defined in the specified notification policy. You can select an existing notification policy or create a new one. For more information, see Notification policies. Note Click View all notification policies to view notification policy details.
   Advanced alert settings
   No data	This setting handles data anomalies, such as no data, issues with composite metrics, or period-over-period comparisons. If metric data is unavailable, you can choose to report a value of 0 or 1, or suppress the alert. For more information, see Alert management glossary.
