The number of messages present in a queue or semaphore over time.
Kernel objects used for inter-process communication (IPC) include
FreeRTOS queues and the various types of semaphore. The number of items in a queue is incremented
each time the queue is successfully written to, and decremented each time the queue
is successfully read from. In the same way, the count associated with a semaphore is incremented each time
the semaphore is successfully 'given',
and decremented each time the semaphore is successfully 'taken'. The kernel object
utilisation view shows the count associated with a queue or semaphore over
a period of time.
