Select Components to MonitorWhen 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:
|J2EE 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.
|J2EE 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 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 Module Icon||This item represents a group of Stateless, Stateful, Entity and Message Driven EJBs, nested in the same JAR archive file.|
|JTA Resource Icon||This icon symbolizes a Java Transaction Resource object.|
|JCA 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.|
|JDBC 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.|
|Servlet Icon||This item symbolizes a Servlet, and you will see statistics about this Servlet under this icon.|
|EJB 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
On the screenshot below, the "PetStore" Application does not exist.
