Use IBM Support Assistant

IBM Support Assistant is a free troubleshooting application for WebSphere Application Server containing various support features and tools.

We can customize IBM Support Assistant by installing the problem determination tools needed to troubleshoot various problems. For example, when the JVM runs out of memory, application threads hang, the JVM crashes, or if performance declines, we can use analysis tools to diagnose these problems.

Classloader Analyzer

Analyze Java classes, Java classloaders, and libraries from Java classloader trace files and IBM javacore files.

The Classloader Analyzer offers these features:

Editions: Desktop




Garbage Collection and Memory Visualizer

Analyze and visualizing verbose GC logs to help you:


The IBM Monitoring and Diagnostic Tools for Java - Garbage Collection and Memory Visualizer (GCMV) provides analysis and views of your application's verbose gc output. GCMV displays the data in both graphical and tabulated form. It provides a clear summary and interprets the information to produce a series of tuning recommendations. GCMV parses and plots various log types including:


Editions: Eclipse, report, desktop



Health Center Monitor the status of a running IBM Java Virtual Machine (JVM) to help you:


The IBM Monitoring and Diagnostic Tools for Java - Health Center is a lightweight tool that monitors active IBM Virtual Machines for Java with minimal performance overhead. The Health Center suggests live tuning recommendations for Garbage Collection, profiles methods including call stacks, and highlights contended locks. This information can help you optimize performance, improve stability and optimize system resource usage.

Editions: Eclipse, desktop



HeapAnalyzer

Analyze Java heap dumps to troubleshoot problems such as:


IBM HeapAnalyzer analyzes Java heap dumps and produces a summary report identifying leak suspects and showing statistics about the heap such as number of objects, number of references, number of classes, heap size and so on. It then lets you search and visually inspect the heap with graphical and tabular views.

Editions: Desktop



Interactive Diagnostic Data Explorer (IDDE)

Analyze artifacts produced by IBM Java Virtual Machines (JVM) to help you troubleshoot memory leaks and other problems in Java applications.

The IBM Monitoring and Diagnostic Tools for Java - Interactive Diagnostic Data Explorer (IDDE) is the strategic tool for allowing interactive analysis of JVM problems using post mortem artifacts such as core files or javacores. It is a lightweight tool which lets quickly get information from the artifact we are investigating where we aren't sure what the problem is and you want avoid launching resource intensive analysis. Its features include:



Editions: Eclipse, desktop, web



Memory Analyzer

Analyze system dumps and Java heap dumps to help you:


The IBM Monitoring and Diagnostic Tools for Java - Memory Analyzer can analyze heap dumps with hundreds of millions of objects, quickly calculate the retained sizes of objects, see what is preventing the Garbage Collector from collecting objects, run a report to automatically extract leak suspects and more. It is based on the Eclipse Memory Analyzer (MAT) project.

Editions: Eclipse, web, report, desktop



Pattern Modeling and Analysis Tool for Java Garbage Collector

Analyze verbose GC logs to help you:


IBM Pattern Modeling and Analysis Tool for Java Garbage Collector (PMAT) parses verbose GC logs to show how heap use changes over time as a result of garbage collection activity. Its graphical and tabular reports help you tell if there is excessive memory usage, if the heap is becoming fragmented, and if memory might be leaking.

Editions: Report, desktop



Profile Port Checker

Analyze WebSphere configuration files to discover possible port conflicts.

The Profile Port Checker tool scans WebSphere Application Server configuration files for possible port conflicts. It accepts as input one or more .zip or .jar files that contain WAS configurations. A report is created listing all the server ports that were found along with any duplicate port settings to help you spot potential port conflicts.


Editions: Report



Thread and Monitor Dump Analyzer for Java

Analyze Java core files to help you identify threading problems such as:


The IBM Thread and Monitor Dump Analyzer for Java (TMDA) analyzes javacores and diagnoses monitor locks and thread activities to identify the root cause of hangs, deadlocks, and resource contention or monitor bottlenecks. It compares each javacore and provides process ID information for threads, garbage collection frequency, allocation failure frequency, and a list of hang suspects.


Editions: Report, desktop



Trace and Request Analyzer for WebSphere Application Server

Analyze WebSphere Application Server traces and HTTP Server Plug-in files to identify performance problems.

The WebSphere Application Server trace facility is used to obtain detailed information about running components, including application servers, clients, and other processes in the environment. It helps you find delays and possible hangs by examining WebSphere Application Server trace files and HTTP server plug-in traces. It also helps to identify delays between HTTP requests and responses and delays, and hangs during application execution.


Editions: Desktop



WAIT Javacore Analyzer

Analyze javacores to quickly determine bottlenecks in Java applications.

WAIT can diagnose a a variety of bottleneck types such as:

Editions: External web



Web Server Plug-in Analyzer for WebSphere Application Server

Analyze WebSphere Application Server plug-in configurations to help us find improper or ill-advised settings that could result in runtime problems.

The IBM Web Server Plug-in Analyzer for WebSphere Application Server helps you discover potential problems with trace and configuration files. Its features include:

Editions: Desktop



WebSphere Application Server Configuration Visualizer

Visualize a WebSphere Application server configuration for the purposes of understanding connections and interactions between components.

The WebSphere Application Server Configuration Visualizer generates an interactive HTML visualization of a WebSphere Application Server configuration, including Service Integration Buses and databases. It accepts any combination of zips or jars containing configuration directories. Configurations from multiple nodes in a cell will be merged into a single visualization, and multiple cells can be displayed in the output.

WebSphere Cross Component Trace Logviewer

View augmented Cross Component Trace correlation log records.

IBM WebSphere Cross Component Trace Logviewer provides enhanced log file views for logs augmented with Cross Component Trace correlation log records. Logs can be displayed in flat or hierarchical layouts, and multiple logs can be loaded and viewed simultaneously with log entries related to each request conveniently grouped.
