Historical Statistics
Using Baselines
5967–9446 487
A large spread between low and high baselines indicates that the param-
eter fluctuates significantly over time.
High and low baselines are useful in determining what is normal for
your network which, in turn, helps you identify abnormal events. This
information is helpful when setting alarm thresholds, as discussed on
page 430.
You can specify a different confidence level with the pmReporter
command.
