Chapter 16: Performance Monitoring 262

NOTE: The aggregate value is scheduled to be calculated every five

seconds; however, the calculation may be delayed. For example,

depending on the activity on the system, the aggregate value

could be calculated every seven seconds. As a result, the

aggregate value on the dashboard might not match the sum of the

counter values on the servers at some report points, as the counter

values are updated every five seconds. In this case, the updated

aggregate value will be shown in the next five to 10 seconds.

View Counter Details

When you click the Detail button for a particular counter, you will see

some additional information about the counter, including the name of the

counter and the associated performance object (either CPU, memory,

filesystem I/O, or system). The Detail view also shows performance

information for each instance of the performance object. For example, the

Detail view for the Average CPU utilization counter shows the

performance for each individual CPU, as well as the aggregate value.
