[TechNote] Problem Determination Tools for IBM Support Assistant 5



Product documentation


Abstract

IBM Support Assistant 5 provides a tooling platform for you to easily use various problem determination and analysis tools at no charge. This document contains a list of tools available for IBM Support Assistant 5.

Content

Problem determination tools for IBM Support Assistant 5 are delivered through IBM Installation Manager and through its Tools Administration feature. This allows you to easily discover, install, and update the base application and individual tools. See the IBM Support Assistant 5.0 Team Server announcement for additional information on installing Support Assistant and optional tools.
There are 3 different editions (i.e., styles) of tools and each has different advantages. Many tools are available in more than one edition.
  • Report tools are non-interactive applications that generate analysis reports of a tool's findings.
  • Web tools provide a rich, interactive interface in the browser while the analysis of diagnostic files occurs on the IBM Support Assistant server.
  • Desktop tools are interactive applications that run on your workstation.

Many IBM Support Assistant Team Server tools are provided as-is, but you may post questions or problems with them on the IBM Support Assistant forum.
Available tools:

HeapAnalyzer

What it's used for:
 Analyzing Java heap dumps to troubleshoot problems such as:
  • Memory leaks
  • Excessive heap usage

Description: 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)

What it's used for:
 Analyzing artifacts produced by IBM Java Virtual Machines (JVM) to help you troubleshoot memory leaks and other problems in Java applications.
Description: 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 you quickly get information from the artifact you are investigating where you aren't sure what the problem is and you want avoid launching resource intensive analysis. Its features include:
  • Supports system cores, IBM javacores, and PHD files
  • Full content assist for commands
  • Syntax highlighting
  • Investigation log which mixes free text with live session data
  • Multiple JVM support
  • Encryption of analysis files for secure storage
  • Caching for high performance
  • Support for IBM Dump Analyzer commands

Memory Analyzer

What it's used for:
 Analyzing system dumps and Java heap dumps to help you:
  • Troubleshoot memory leaks
  • Understand the architecture of your Java application through footprint analysis
  • Improve performance by tuning memory footprint and optimizing Java collections and cache usage
  • Customize analysis with additional plug-ins and reports

Description: 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.

Pattern Modeling and Analysis Tool for Java Garbage Collector

What it's used for:
 Analyzing verbose GC logs to help you:
  • Fine tune the Java heap
  • Visualize garbage collection behavior
  • Determine if memory might be leaking


Description: 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.
