Request ability to group agents to a particular registry variable.
ie. 60 Oracle agents deployed on various hosts & 30 of them need to have their DBADMIN registry variable set to a particular email address.
In Foglight4, this was accomplished by creating a Registry Group but the 'Groups' concept does not apply in Foglight 5 since alerts are not agent or host based, they're model based.
Feature doesn't exist in current version 5. Keep checking if enhancement request FGLUI-3326 has been implemented in upcoming versions of Foglight.
Although grouping of hosts and/or agents for the purpose of assigning to a registry variable is not yet available, the ability to route email notifications from select Hosts or Agents to select administrators does exist in
SOL44638 , which may be what you are really looking for.
Enhancement request FGLUI-3326 has been submitted for "grouping of hosts and/or agents to assign to a registry variable" to Development for consideration in a future release of Foglight.
