Reviews : JInspired JDBInsight 3.0 Early Access :

Exceptions Perspective

You can probably guess what this perspective highlights: exceptions. It is a nice, clean display of JDBC errors, including the SQL code and stack trace. See Figure 5. JDBInsight 3.0

Tracing, Console and Other Features

In addition to the standard views above, JDBInsight also provides an additional way to get data. I find the tracing feature quite nice. Using tracing, you can do the following:
  • Concurrency monitoring allows for analyzing what happens to the application at the transaction and SQL level under different loads. Detecting maximums and looking for performance slow downs.
  • Non-database issues within a transaction can be monitored and graphically analyzed, allowing the developer to see where some code-based performance issues may lie.
  • Nested transactions can be seen visually in terms of their performance time.
  • Debugging information can be viewed, including object id's and other data that could be critical in finding code and run-time application issues.

JDBInsight has a command-line console application. This can be helpful when analyzing multiple machines over a network. This profiler returns detailed information in a highly readable (obviously text-based) format. This feature is great for those who prefer command-line operation, for getting quick checks or potentially even automating some process from external applications, and basically all of the other reasons many developers prefer these types of interfaces.

There are even more features available in this application - and the depth that the aforementioned features go needs to be seen to be understood.

Conclusion

Having been developing J2EE and enterprise applications for a number of years now, I'm surprised that JDBInsight is in a class by itself. Virtually every enterprise application can benefit significantly from just this sort of analysis. The licensing fees for JDBInsight are extremely reasonable, enough for the budgets of independent developers and a pittance to the Fortune 1000 companies who would likely discover a significant return on investment almost instantly after deploying this application. I would recommend this application to anyone who develops J2EE applications of any scope that use JDBC.
