ParameterDescription
EnabledSelect to enable the rule.
Name*Name of the rule. This is a required field. 
DescriptionA description for the rule to give an idea about what alerts get aggregated.
Match Conditions*

Query Builder - Select if you want to build a query with various conditions that can be grouped. You can also have nested groups of conditions.

Match Conditions - You can set the value to All of these, Any of these, or None of these. Depending on what you select the the criteria types specified in the Conditions and Group of conditions are matched to group the alerts.

For example, if you set the match condition to All of these, alerts that match the criteria mentioned in the Conditions and Group Conditions are grouped into one incident.
Add a Condition to be matched by clicking <>
Add a Group of Conditions by clicking <> and adding conditions by clicking <>
You can include multiple Conditions and Groups of Conditions that can be matched as per criteria set and group the incoming alerts into incidents.

Advanced - Select if you want to add an advanced query builder. You can add a specific condition that needs to be matched as per the matching option selected.

For example: you can type the criteria builder format {"$and": [{"alert.severity" : {"$gt":4}}]} to group alerts that have severity greater than 4.

Action

Group into an Incident - If enabled, the alerts that match the criteria set are grouped into an alert.

Suppress the Alert - If enabled, the alerts that match the criteria are suppressed.

Grouping Options*

Group By: The criteria to group the alerts as per the specified category. You can group the alerts with no attributes (all matching Alerts grouped together), 1 attribute, or 2 attributes. Grouping on an attribute means that all matching Alerts containing the same value for that attribute are grouped together in the same Incident.

Time Window: The time range specified to group alerts.
For example if the time window is set to 1 hour, all alerts that match the criteria set in Group By field and that arrive within an hour of each other are grouped into an incident.

Incident Options

Title - (Optional) Title of the incident. You can provide placeholders based on the attributes you grouped. Placeholders are optional. If you do not use placeholders, all Incidents created by the rule will have the same title.

For example, if you grouped them according to the source, you can name the resulting Incident as Alerts for ${groupByValue1}, and the incident for all alerts from ECAT would be named Alerts for ECAT.

Summary - (Optional) Summary of the incident.
Category - (Optional) Category of the incident created. An incident can be classified using more than one category.
Assignee - (Optional) Name of the assignee to whom the incident is assigned to.
Priority

Average of Risk Score across all of the Alerts - Takes the average of the risk scores across all the alerts to set the priority of the incident created.

Highest Risk Score available across all of the Alerts - Takes the highest score available across all the alerts to set the priority of the incident created.

Number of Alerts in the time window - Takes the count of the number of alerts in the time window selected to set the priority of the incident created.

Move the slider to adjust the scale that sets the priority level of the incident.

NotificationsA set of email addresses of the users to be notified when incidents are created by this rule.
