About Ordering the Node Groupings

The system uses each node grouping in the order you list them on the Node Grouping tab of the Broker Display Options page. For each node grouping, the Match Type and Match Name fields determine the Brokers or clients that are in the grouping. Order is important because after a Broker or client is added to a node grouping, it is no longer available for consideration in any other node groupings.

For example, assume you have clients with the following client IDs: north1, north2, north3, northwest1, northwest2. You define the following node groupings in the following order:

Match Type	Match Name	Visible	These clients display in the topology view
Client ID	northwest*	no	north1 north2 north3
Client ID	north*	yes

Because the node grouping to hide clients with client IDs that start with "northwest" is listed first, the clients northwest1 and northwest2 are included in the first, hidden node grouping and are therefore not available for the second, visible node grouping.

However, if you switch the order of the node groupings, as shown below, the clients with client IDs that start with "northwest" are displayed because they would be a part of the first, visible node grouping, and therefore they are not available for the second, hidden node grouping.

Match Type	Match Name	Visible	These clients display in the topology view
Client ID	north*	yes	north1 north2 north3 northwest1 northwest2
Client ID	northwest*	no

You should set your display settings as follows:

1. Use the Display Options tab to indicate whether you want the system to include disconnected Brokers, remote Brokers, or disconnected clients in the topology view. For more information, see Defining How to Display Data in the Broker Topology View.

2. Order the node groupings to hide the Brokers and clients that you do not want included in the topology view. Create the node groupings and ensure the Visible check box is not selected.

3. Create groupings that you mark as visible and set the Combined check box based on whether you want the system to display members of the group using individual nodes or combined as a single node.
