Working with Cluster Explorer

Active and inactive nodes are shown in Cluster Explorer for a quick view of system health. Using Cluster Explorer, you can use functionality available at various nodes on the left, and you can view information about that node level on the right.

The Cluster Explorer shows the hierarchy of cluster members. Inactive agents (which could be standby agents or failed agents) are dimmed.

The structure of the cluster member hierarchy is as follows:

Site

   Cluster

      Machine (host name)

         Process (Processing Unit or JVM process ID)

            Agent (ActiveService Gateway Class agent)

      Cache Objects

Where:

•	Site is the root.

•	Cluster shows the name of the cluster being monitored.

•	Machine shows one or more machines within the cluster. They run the cluster processes (process units or engines).

•

Process shows each of the JVM processes (Core Engines) running on a machine. The label for a process that was predefined in the topology file is the process unit ID assigned in the file, concatenated with the process ID enclosed in parentheses. The label for an unpredefined process is the JVM process ID.

•	Agent lists all agents, regardless of their type, running in the JVM process.

•	The Cache Objects panel shows all the objects stored in the cache, without regard to their physical location in the TIBCO API Exchange Gateway cluster.

•	Machines, Core Engines, and agents are all members of the TIBCO API Exchange Gateway cluster.

Navigating Cluster Explorer

To navigate the cluster explorer, do any of the following:

•	Expand Cluster Explorer and select the member you want to work with or whose metrics you want to see. Metrics display on the right.

•	Click an inactive cluster member to display the last available health metrics for that member.

•	Click the minimize button in the Cluster Explorer title bar to minimize the explorer panel.

Starting, Stopping, Pausing, and Resuming Core Engines

To Start, Stop, Pause, or Resume an Engine

1.	From Cluster Explorer, select the engine you want to start, stop, pause, or resume. (You resume a paused engine.)

2.	Click the appropriate icon button: Start, Stop, Pause, or Resume

3.	Verify the login details and click OK.
