The extended alarm entry performs mathematical operation to the sampled valueof the alarm variable, and then the result will be compared with the configured thresholdto implementing the alarm function.Note:Before adding extended alarm entry, you need to define the referenced event in theextended alarm entry by using the rmon event command.You can define up to 50 prialarm entries.Perform the following configuration in system view.
