Debugging is like plumbing; it involves fixing difficult, hidden problems — so, besides the vital experience, both debuggers and plumbers must have a specialised set of tools at hand for each task. Targeted at Linux kernel newbies and kernel debuggers, this article introduces two tools, Kprobe and Jprobe, which are simple, and get the work done. Please enter your comment!

The -4, ms value indicates a reduction in the time spent executing in the assignData method. However, it has many advantages: Other areas that JProbe Profiler can assist you in is identifying long running methods in third-party components as well as identifying inefficient interactions with JDBC classes such as long running SQL commands and inefficient result set processing.

For now, we will just hide this information and proceed with investigating the performance characteristics of our own code. You will get the most benefit from analyzing profile data when you work with your application in terms of typical use cases. Most of the tools are focused on memory analysis, while I needed execution time analysis. Once we have hidden the method call in the third party control, we are quickly alerted to the next hot spot, which is in the StockChartDataSource.

JProbe Memory Debugger can monitor sessions in real-time and capture snapshots for analysis at a later time. What I like most about this window is the two lower bars that give you an estimate on how intensive this profiling session is going to be in terms of memory and CPU usage. Setting up an Application Server Integration with the Settings Wizard is quick and simple, you specify the type and version of Application Server along with any required Java parameters.

In the LaunchPad, we select the pre-configured Application Server we are using and what classes we would like to analyze. The Application Server Integration can then be saved to a globally accessible directory for use by other developers.

Jul 04, 3 min read by Steven Haines. It took me less than half an hour to start profiling including the download and installationwithout any prior knowledge of the product and without reading any documentation. At this point we need to validate that our code changes have had a positive impact on the performance of our application. JProbe helps developers to understand what? Integrating with popular Application Servers is a yutorial task jprobw JProbe? Upon initial inspection of the Call Graph window, the assignData method is no longer displayed as a hot spot see Figure We continue to perform the use case and navigate through four of our favorite stocks.

Not having to jump out of your IDE and open up a separate console to perform your unit tests can provide a boost in productivity and efficiency.

A couple of weeks ago I found myself in a position which is well known to any professional Java developer:. Website: Go to site Description: JProbe is software that analyzes Java code in development environments by providing diagnostics on memory usage, performance, and test coverage.

This software allows developers to examine the cause of application code performance and stability problems.
