Deployment monitoring involves several dimensions:

System monitoring: How well is the server hardware servicing the application load?
Basic system responsiveness: How well is the server responding from an individual client's point of view? (Note that this is the simplest place to start and includes both server and network performance. )
Web application server monitoring: How well is the web application server handling requests and resource pools?
Jazz server monitoring: What is the Jazz-based server application being asked to do by the overall user population and how well is it doing it?

Monitoring: Where to Start?

Enterprise Monitoring

The key to a stable, reliable distributed system is to monitor the moving parts of the system. It is strongly recommended for CLM Deployments to deploy professional monitoring tools for production.

Application Managed Beans

Jazz server monitoring

JMonitoring and TroubleShooting Guide provides a general view into the monitoring capabilities available for checking system stability and troubleshooting problems across the CLM application and software stack.
JTSMon will help you make more sense out of Jazz server traffic patterns by turning web service reports into time trend spreadsheets and graphs. To get a copy of JTSMon see the JTSMonFAQ.
Jazz monitoring through JMX provides how to set up JMX to monitor a Jazz Server.

Web and Application Server monitoring

WebSphere Performance Monitoring Infrastructure (PMI) is the core monitoring infrastructure for WebSphere Application Server.
Websphere Liberty's Admin Center for monitoring shows how to access the Admin Center which provides basic out of the box monitoring.
CLM monitor is a lightweight HTTP client that uses Perl to detect the health of the CLM server and measures the response time of each round-trip HTTP call.

Basic system responsiveness

Health Check is a provided optional dashboard widget that can be used to periodically check on server responsiveness.
Metronome is a feature in the RTC client that provides understanding as to what the web services are doing and how the services are used by the individual RTC client with each user action.

System monitoring

NMON (AIX/Linux) gives you a wealth of system performance statistics and automatically creates graphs for CPU, memory, disk, and network usage.

Java Virtual Machine monitoring

IBM Java Health Center IBM Java Health Center provides tooling for monitoring and problem diagnosis of running IBM JREs.
The IBM Whole-system Analysis of Idle Time tool (WAIT) can help you pinpoint performance bottlenecks in workloads with a central Java component and produces an HTML report that describes the main bottlenecks.
IBM Monitoring and Diagnostic Tools for Java - Garbage Collection and Memory Visualizer Version 2.7 The IBM Monitoring and Diagnostic Tools for Java - Garbage Collection and Memory Visualizer (GCMV) is a tool that you can use to visualize and analyze the memory usage and garbage collection activity of your Java application.
- Use of IBM Monitoring and Diagnostic Tools - Health Center on Jazz Applications through WebSphere Application Server is outlined at http://www-01.ibm.com/support/docview.wss?uid=swg21693346
