Determining acceptable values for counters A large set of factors determines the normal operating range for each counter in a typical system. you must drive your system through a large number of conditions and develop a sense for normal operating ranges for your equipment. you shoshould record these typical values in log files for future reference. then, as you make changes to your workload or your hardware, you can refer to your earli
