IBM Tivoli Composite Application Agent for J2EE, Version 7.1.1

Overview of the monitoring and diagnostic capabilities

ITCAM Agent for J2EE can monitor J2EE application servers and J2SE applications, providing information within two different infrastructures: IBM® Tivoli® Monitoring and ITCAM for Application Diagnostics Managing Server.

The IBM Tivoli Monitoring environment places this agent into the context of the IBM Tivoli Monitoring family, a suite of products used to monitor a mixed-systems environment. With IBM Tivoli Monitoring, the user can:

Monitor for alerts on the managed systems
Trace the causes leading up to an alert
Monitor processing time for various requests within J2EE and J2SE applications
Establish your own performance thresholds
Create custom situations, which are conditions that IBM Tivoli Monitoring automatically monitors
Create and send commands to control system monitoring using the Take Action feature
Create comprehensive reports about system conditions
Define your own queries, using the attributes provided with ITCAM Agent for J2EE, to monitor conditions of particular interest to you

The Tivoli Enterprise Portal is the user interface for the IBM Tivoli Monitoring environment. It provides an overall view of the enterprise network; from this view, the user can "drill down" to examine components of the environment more closely. The Portal includes information from different agents that monitor various parts of the environment; ITCAM Agent for J2EE is one of them.

For details on capabilities of IBM Tivoli Monitoring, and information on deploying the IBM Tivoli Monitoring infrastructure, see IBM Tivoli Monitoring: Installation and Setup Guide.

Figure 1 shows how ITCAM Agent for J2EE interacts with other IBM Tivoli Monitoring components.

The Managing Server is a component of ITCAM for Application Diagnostics. Its Visualization Engine provides a user interface for "deep dive" diagnostics information. This user interface is a good solution for software developers and performance analysts.

Most information provided by ITCAM Agent for J2EE and available through the Tivoli Enterprise Portal can also be viewed through the Visualization Engine. The Visualization Engine also provides additional diagnostic information, including:

Method entry/exit and stack tracing,
Lock analysis,
Heap object analysis for memory leak diagnosis,
Thread information,
"In-flight" request analysis to detect malfunctioning applications.

For details on the capabilities of ITCAM for Application Diagnostics Managing Server, and information on deploying it, see IBM Tivoli Composite Application Manager for Application Diagnostics Managing Server Installation Guide.

The diagram on Figure 2 shows how ITCAM Agent for J2EE interacts with the components of the Managing Server. (The Data Collector is a component of the Agent).
