Most of the time, without giving any indication why those methods are being executed. However, time profiling only shows "hotspots", the methods that are being executed Of the application being profiled can also be very small. Instructions being executed, the impact on the overall performance Usually at regular time intervals, but it can recorded when any specific event occurs.Īt post-processing time, these addresses are converted to symbols andĬounts of these events are reported for each symbol, module, thread, and process.īecause the number of these events can be very small compared to the total number of This style records the address currently being executed by each processor, Styles of Execution Profiling Performance Inspector provides three fundamental styles of execution profiling,Įach with its own advantages and disadvantages. In the Linux Trace Toolkit, Oprofile, and dProbes. You can find tools with similar capabilities to some of our tools Licensing Information section for more information. The majority of this project is LGPL code, and the rest is GPL. To capture performance related information. The package may also include a device driver,Īnd may use a pinned buffer per CPU along with kernel hooks, To measure system events at the process level. Performance Inspector uses the performance counters provided by the CPUs, if available, Which may be reduced due to the capabilities of the platform on which it is executed. This documentation describes the maximum capabilities of our tools,

Performance Inspector works with both Java™ and C/C++ applications The tools can be used to help identify performance problems in your application,Īs well as how your application interacts with the operating system. Of your applications and the resources they consume. These tools will help you gain a better understanding of the performance The Performance Inspector™ packages contain suites of performance analysis toolsįor Linux®, Windows®, AIX®, and ZOS® platforms. Overview The Performance Inspector™ packages are provided AS IS, with no implied support. Performance Inspector Performance Inspector™ This project is no longer under active development.
