It varies depending on the system role and are several general counters and specific thresholds for these counters that you can use to monitor should examine these counters as ratios over a period of regular intervals rather than as the average of specific instances. This will provide a more realistic picture of the actual activity occurring on your system. In addition watch for consistent occurrences of the threshold values being exceeded. It is not uncommon for momentary activity in a system to cause one or more counters to exceed threshold values which may or may not be acceptable in your environment. You can use System Monitor and Performance Logs and Alerts to monitor the local system or another computer on the network as shown in Figure . It can be useful to compare the performance of the same resource on multiple systems. Be cautious when you do this though. Ensure that you are comparing appropriately similar objects. Watch out for the apples and oranges mismatch. Also consider that a server being monitored locally may have less monitoring overhead than one that is monitored remotely. This is particularly true regarding the network- and server-related counters which can be skewed by the transmission of the performance data to your monitoring system. Be sure to account for this difference when developing your statistics.
