Abstract
Technical solutions are described for determining and analyzing timing parameters to prognosticate a failure of one or more RTOS tasks. An example method includes dequeing a buffer queue entry from a buffer queue. In response to determining that a first task-id from the buffer queue entry does not match a second task-id from a topmost entry of a stack comprising buffer queue entries, the method includes pushing the buffer queue entry as a top-entry in a stack, updating a previous time sample value as the timestamp of the buffer queue entry, and accumulating a temporary execution time value for the second task-id from the stack. Further, in response to the first task-id matching the second task-id, computing an execution time value for the second task-id, updating the previous time sample value as the timestamp of the buffer queue entry, and popping the topmost entry from the stack.
