The Group page defines the Job Group and its members.
Name
Enter a unique descriptive name for this group.
Enable this group
If this option is not checked, the group can still be used on jobs, but it will not receive notification messages until it is enabled.
Severity
Use this option to specify the severity conditions that a notification message must meet in order to be sent to this group. Any message that does not meet the condition will not be sent to members of this group.
You can specify severity conditions for an individual member in the properties for that member.

Add, change, or remove group members.
