Applications 

The Applications node of the monitoring tree displays monitor data for the Java Enterprise Edition 5 applications that have implemented the monitoring functionality. By default, you can see here the Table Buffers monitor.

Table Buffers Monitor

Table buffering is one of the most important performance-related features of Open SQL. A separate table buffer is maintained for each server process in the cluster. For more information, see Table Buffer in the Development Manual.

This component shows the monitored data for Open SQL table buffers.

Monitored Unit	Description
BufferSize	The maximum size of the table buffer.
FreeSize	The remaining free space in the buffer in bytes.
HitRate	The ratio between buffer hits and requests.
Number of displacements	The total number of displacements in the buffer since buffer instance startup.

CAF State Monitor

The CAF State Monitor shows the state of the two major components that you need to start, so that your composite application is working properly.

Monitored Unit	Description
Core Application	Indicates whether the caf.core application is started or stopped. It contains predefined,  commonly-used services and data types for your composite application.
Runtime Application	Indicates whether the runtime application is started or stopped. You need to start this application to be able to run all other CAF applications.
