VMware vFabric tc Servers


Monitored Parameters

Applications Manager monitors the VMware vFabric tc Server and the Spring applications deployed on the server to detect any performance problems. This monitoring is carried out by tracking critical components of the vFabric tc Server such as memory, thread, throughput, garbage collector,etc.

The Availability tab shows the availability history of the vFabric tc Server for the past 24 hours or 30 days. The Performance tab shows some key performance indicators of the vFabric tc Server such as CPU utilization, throughput and garbage collection rate. This tab also shows the health status and events for the past 24 hours or 30 days.


The List view lists all the vFabric tc Servers monitored by Applications Manager along with their overall availability and health status. It enables you to perform bulk admin configurations. Click on the individual monitors listed to view detailed performance metrics.


To view detailed performance metrics of a vFabric tc Server, click on the monitor name listed in the Availability or List View tabs. The performance metrics have been categorized into 6 different tabs:


This tab provides a high-level overview of the health and performance of the vFabric tc Server along with information pertaining to the throughput, thread and garbage collection.



Monitor Information


The name of the vFabric tc Server monitor


Denotes the type you are monitoring


Denotes the health status of the vFabric tc Server(clear, critical, warning)

Host Name

Specifies the host at which the vFabric tc Server is running.

Last Polled at Specifies the time at which the last poll was performed.
Next Poll at Specifies the time at which the next poll is scheduled.
Today's Availability Shows the overall availability status of the server for the day. You can also view 7/30 reports and the current availability status of the server.

You can use the Custom Fields option in the 'Monitor Information' section to configure additional fields for the monitor.



  • Support given for JDK 1.8: When monitoring with JDK 1.8 MetaSpace, Applications Manager monitors and displays new memory space called MetaSpace and Compressed Class Space instead of the former Permanent Generation (Non-Heap).


The Memory Details section shows the memory usage values of the vFabric tc Server. This section specifies the memory which is being used, available memory for the JVM, heap memory usage and total memory used by the JVM.


The CPU Usage graph display the CPU Usage values in percentage.


The Throughput section displays information about the number of requests received and sent per second in the server. The error count and the processing time taken for the requests in milliseconds, are also specified.


The Thread Details section shows the total number of threads count, number of threads in the running state, threads that are waiting for a task and blocked threads in the JVM, timed waiting threads and deadlock threads.


The Garbage Collector section provides details regarding the garbage collected by the JVM. The Garbage Collection rate and the average time required for the same in milliseconds is also specified. Click on the values to view the graphical representation. You can disable, enable and delete the instances using the Actions option. The Compare Reports option can be used to have the comparison of the various instances with the selected metrics.
