Overview of the monitoring and diagnostic capabilities
Overview
ITCAM Agent for WebSphere Applications is a component of ITCAM for Application Diagnostics, V7.1.0.1.
ITCAM Agent for WebSphere Applications can function within two different infrastructures:
- IBM Tivoli Monitoring
- ITCAM for Application Diagnostics Managing Server
IBM Tivoli Monitoring places the 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
- Trace causes leading to an alert
- Monitor request processing time
- Establish performance thresholds
- Create conditions for custom situations
- Send Take Action commands
- Create system condition reports
- Define queries using attributes
The Tivoli Enterprise Portal is the user interface for the IBM Tivoli Monitoring environment, providing a view of the enterprise network. From this view users 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.
The Managing Server is a component of ITCAM for Application Diagnostics. Its Visualization Engine provides a user interface for "deep dive" diagnostics information. The user can "click through" or "launch in context" to the Visualization Engine from the Tivoli Enterprise Portal when detailed information is required. The Visualization Engine can also be used as a stand alone user interface; this user interface is a good solution for software developers and performance analysts.
Most information provided by ITCAM Agent for WebSphere Applications 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 ITCAM for Application Diagnostics Managing Server Installation Guide.
The data collector is a component of the agent.
