Viewing Topology for a Cluster

Display the topology view of a cluster which represents the entire cluster and consists of nodes and database servers.

Prerequisites

Enable the time-granularity option on the node in the Event Stream Processor project configuration (.ccr) file. See the Event Stream Processor Administrators Guide for information on the project configuration file.
Log in using the espMonitorRole role to be able to perform this task.

Task

Topology is a graphical representation of how the ESP nodes and Sybase IQ, Adaptive Server Enterprise, and HANA database servers are connected to each other. It is a network diagram that provides a visual map and the status of Event Stream Processor nodes, output adapters, and the databases to which they connect.

In the Perspective Resources window, select the node, click the arrow, and select Monitor Cluster.
In the left pane of the ESP Cluster Monitor view, select Topology.
Nodes appear as icons and indicate different node roles. Valid roles include:
- Manager
- Controller
- Manager and Controller
Database servers appear as icons. You can connect ASE, Sybase IQ, and HANA database servers to any node in the cluster using an output adapter. You can also right-click the Sybase IQ and ASE servers to register unregistered servers.
Valid database servers include:
- ASE
- Sybase IQ
- HANA
To view node status, hover the mouse pointer over a selected node.
Valid statuses include:
- Running
- Unknown
To view if a node is authenticated, right-click on a selected node. If the Monitor Node command appears, the node is authenticated.
A line connecting controller nodes to Sybase IQ, ASE, and HANA database servers with one or more adapters in loaded projects. To view adapter status, hover the mouse pointer over a selected line.
Valid statuses include:
- Running
- Stopped
- Mixed
