"...Like the expensive time-tracing solutions available for many proprietary embedded RTOS solutions, LTT provides developers with all of the information necessary to reconstruct a system's behavior over a certain period of time. Using LTT, one can graphically view the precise dynamics of a system answering such questions as:

  • Who actually has access to the hardware during a specific time slice?
  • What happens to an application when it receives data?
  • Where are the I/O latencies in a given application?
  • When is a specific application actually reading from disk?
  • Why do certain synchronization problems occur?"

"LTT provides this related information through three primary graphical and text information displays which map the system's lowest level processes (such as scheduling decisions, process switches and various management tasks) to each high-level application -- all plotted against the time axis."
