Chapter 14 Monitoring Your Network
Displaying Network Topology Maps
Procedure
Step 1 Do one of the following:
• Display the list of virtual servers by choosing Monitor > Virtual Contexts > Loadbalancing >
Virtual Servers.
The Virtual Servers window appears with the table of configured virtual servers.
Topology Map Displays network node mapping.
The node icons display the following information related to the node:
• Name
• IP address (virtual and real servers only)
• Port (real servers only)
• Operational state (virtual and real servers only)
When you hover over a network node icon, the node type appears, for example ACE Virtual Server,
Server Farm, or Real Server. Other possible operations when you hover over a network node icon are
as follows:
• Real servers only—When you have an ACE configured for Dynamic Workload Scaling and you
mouseover an associated real server icon, information appears that identifies which data center
the real server is located in: local or remote. A timestamp also appears that specifies when the
information was obtained.
• Server farms only—When you mouseover a server farm icon, the following Dynamic Workload
Scaling status information appears:
– Local—The ACE is using the server farm’s local real servers only for load balancing. A
timestamp specifies when the information was obtained.
– Burst—The ACE is bursting traffic to the server farm’s remote real servers because the load
of the local real servers has exceeded the specified usage threshold (based on the average
CPU and/or memory usage). A timestamp specifies when the information was obtained.
– N/A—Not applicable (Dynamic Workload Scaling is not available).
For more information about Dynamic Workload Scaling, see the “Dynamic Workload Scaling
Overview” section on page 6-4.
To view details about a network node, right-click on the node and choose Show Details from the
pop-up menu. To reposition a node in the map, click and drag the node icon to a new position. The
node interconnect lines move with the node.
Overview Window Provides a combined functionality of the scroll bars and zoom tool as follows:
• Position tool (a)—Click and drag the shaded box to move around the topology map.
• Zoom tool (b)—Click and drag the shaded box handle (located in lower right corner) and to
zoom in or out of the topology map.
Click the Overview toggle button in the map tool bar to display or hide the Overview window (see
Topology map tool bar).
