Using the IBM Monitoring and Diagnostic Tools
The IBM® Monitoring and Diagnostic Tools are a set of GUI-based tools which you can use to monitor your applications, analyze resource usage, and diagnose problems. The tools can help you to optimize application performance, improve application stability, reduce resource usage, and resolve problems more quickly.
The tools provide output in various formats, such as tables, charts, graphs, and recommendations.
Use this output to complete the following diagnostic tasks:
- Detect deadlock conditions
- Monitor thread activity
- See which methods are taking the most time to run
- See which objects are using the most memory
- Find memory leaks and I/O bottlenecks
- Analyze the efficiency of Java™ collections, such as arrays
- Understand the relationships between application objects
- Visualize garbage collection performance
- Get recommendations for tuning the Java virtual machine (VM) and improving application performance
- Garbage Collection and Memory Visualizer
- Analyze the memory usage, garbage collection behavior, and performance of applications, by plotting verbose garbage collection data from dump files. Tuning recommendations are also provided.
- Interactive Diagnostic Data Explorer
- Use commands to extract information from dump files. This tool is a GUI-based version of the jdmpview command, with extra features.
- Memory Analyzer
- Analyze the memory usage and performance of applications, using data from dump files.
