Select Components to Monitor

When a WebSphere Monitor collector is started as part of a job, it automatically collects some statistics from the WebSphere server defined in the Target Parameters. In order to avoid storing huge amount of statistics, Web Applications (and their own Servlets) and EJB Modules (with their own EJBs) to monitor have to be specified in the collector editor.

The statistics collected by default are:

The components that need to be specified to be monitored are:

As you can see, there are several existing Components available on a WebSphere server. Here is an explanation of each icon :

Icons available from the Components and Selected Components Lists

ServerJ2EE Server Icon This item is the root of the components tree. All components of the current server are displayed under this item.
Generally, you will have only one Icon Server by WebSphere server, but if you use multiple instance of WebSphere Application Server, then a connection to this server might display severals server icons.
ApplicationJ2EE Application Icon  This item corresponds to a specific J2EE Application. A J2EE Application in WebSphere server is a group of EJB Module and Web Applications, dedicated to a specific application.
Web ApplicationWeb Application Icon This item represents a group of servlets, nested in the same WAR file or directory for example. You can also know this group as a Web Module.
EJB ModuleEJB Module Icon This item represents a group of Stateless, Stateful, Entity and Message Driven EJBs, nested in the same JAR archive file.

Icons only available from the Preview List

JTAJTA Resource Icon This icon symbolizes a Java Transaction Resource object.
JCAJCA Resource Icon This icon symbolizes a Java Connector Architecture Resource object. It is also known as a JDBC Pool, but can be different than a connection to a database (for example, a connection to a resource file). You will see under this item statistics about the current JCA Resource.
JCAJDBC Resource Icon This icon represents a Java Data Base Connectivity Resource object. This kind of object are used to ensure that the connection to the Database is activated and properly work. It also optimize connections by creating multiple connections instance in a pool, and give them to the developer, as soon it needs it.
ServketServlet Icon This item symbolizes a Servlet, and you will see statistics about this Servlet under this icon.
EJBEJB Icon This item symbolizes an EJB (Stateless, Stateful, Entity or Message Driven), and you will see statistics about this EJB under this icon.

To select additional components to monitor:




Note: if some previously selected components do NOT exist on the WebSphere target (because they were removed or because the target has changed since collector definition), a red cross on their icon makes them visible.
On the screenshot below, the "PetStore" Application does not exist.
