Histogram information
This section discusses the following topics:
• Histogram information overview
• Displaying CPU histogram information
• Displaying buffer histogram information
• Displaying memory histogram information
Histogram information overview
The histogram framework feature monitors and records system resource usage information. The
main objective of the histogram is to record resource allocation failures and task CPU usage
information. The histogram feature keeps track of task execution information, context switch
history of tasks, buffer allocation failure and memory allocation failure.
The histogram information is collected and maintained internally, in a cyclical buffer. It can be
reviewed to determine if resource allocation failures or task CPU usage may have contributed to an
application failure.
