Identification of Processor & Memory Issues

Identification of Processor & Memory Issues

Context switches per second:- Context Switches refers to the switching of the processor from a lower priority thread to a higher priority thread. A consistent value of above 15000 per second per processor indicates the presence of too many threads of same priority and possibility of having blocked threads

Faults per second (Memory: Page Faults/sec):- This counter provides the count of how many times the information was not available in the primary memory location where it was expected to be. This indicates the count of soft page faults/sec (available at different location in the primary) and hard page faults/sec (available in the disk). A consistent high Hard Page faults/sec value indicates the memory shortage problem. A high Page Faults/sec value coupled with high memory:Pages/sec indicates the shortage of memory
