Distributed Analyzer Version 1.0


Error Detection in distributed applications : Error Detection in distributed applications : Problem and SolutionProblem and Solution

Problem:Deploying unreliable or poorly performing web-based distributed applications

Why is it a problem?Negative business implications

Why is it more difficult than traditional client server development?The variety and number of complex technologies which are both distributed and tightly integrated

What’s the solution:

A software development tool that easily identifies program errors and performance issues during the development of a distributed application. The tool directs the web professional to the location of the problem and recommends appropriate follow-up measures. In its collection and presentation of results the tool guides the user towards greater understanding over the complexities of building distributed applications.

Distributed Analyzer: a tool for developersDistributed Analyzer: a tool for developers

Captures critical events across multiple systems

Captures information without instrumentation or source code

Displays distributed event information in context with other

events, program problems and performance issues

Correlates disparate data into information within a single

view of a multi-hosted distributed application

Leverages expert knowledge on behalf of the user

Helps organizations prioritize critical developer resources

Reduces complexity and enhances program understanding

Quickly identifies and localizes program problems and

performance issues down to the tier or component
