Options to Customize Performance Thresholds

Specify a performance threshold value by:

• Entering a Sensitivity level. The management console dynamically generates a threshold value based on the Sensitivity level.
• Entering a static value in milliseconds or specify a percentage
• Disabling a metric threshold

By default, the Sensitivity option is enabled. No matter which method is used, the threshold always includes a value for the minimum number of observations. An observation is an opportunity for the management console to calculate a metric from a TCP transaction. To rate the performance of a metric as Normal, Minor (yellow), or Major (orange), a monitoring device must see a minimum number of observations.

Alternatively, you can choose to not include a particular metric when rating the performance of a network, server, or application.
