Instruments shows a time line displaying any event occurring in the application, such as CPU activity variation, memory allocation, and network and file activity, together with graphs and statistics. Group of events are monitored via customizable "instruments", which have the ability to record user generated events and replay (emulate) them exactly as many times as needed, so a developer can see the effect of code changes without actually doing the repetitive work. The Instrument Builder feature allows the creation of custom analysis instruments. [1]
