Chapter 4: Monitoring with Sybase Central


Monitoring multiplex state and status

The graphical detail pane is available from the Multiplexes container in the Sybase IQ plug-in for Sybase Central. The graphical, topology view visually represents the entire multiplex environment, and complements the existing list view, making it easy to visually monitor the state of the multiplex environment.

The view consists of nodes and links. A node represents a multiplex server, while a link represents a connection between two multiplex servers. Links exist only between the coordinator node, of which there can be only one, and a secondary node. Links cannot exist between two secondary nodes.

You can rearrange the layout by moving nodes in the view; the next time you display the topology view, the most-recently used graphical layout is restored as nearly as possible. (If the multiplex configuration has changed, the layout can be only partially restored.)

You can use the topology view to designate a failover node and to perform failover. See “Designated failover node” and “Failover”.

StepsViewing multiplex topology

The topology view in Sybase Central shows the types of servers in the multiplex and their current states.

  1. In the Sybase Central tree view, select the multiplex name, then click the Topology tab.

You can also print and save the topology view.

StepsPrinting the multiplex topology

  1. Select the multiplex name in the Sybase Central tree view, and switch to the Topology tab.

  2. Right-click in the Topology view, and select Print Graph.

  3. Review your print options and print the page to the desired printer.

StepsSaving the graph

  1. In the topology view, right-click and select Save Graph As.

  2. Specify a file name for the .JPEG file.

  3. Click Save.
