" " Thresholds

This section defines the thresholds or zone borders that can be used to monitor the data collected by a performance variable. There are four input fields in this section:

" " The first field is the Upper Alarm, which is the highest value the monitor will return for a performance variable before issuing any upper alarm actions set for that performance variable.
" " The second field is the Upper Warning, which provides a warning when a performance variable is approaching its upper alarm value.
" " The third field is the Lower Warning, which provides a warning when a performance variable is approaching its lower alarm value.
" " The fourth field is the Lower Alarm, which is the lowest value the monitor will return for a performance variable before issuing any lower alarm actions set for that performance variable.

" " Graph

This section is used to activate or deactivate thresholds. Colors and their intensity are significant:

" " Yellow indicates a warning zone.
" " Red indicates an alarm zone.
" " A bright color means a threshold has been enabled.
" " A dim color means a threshold has been disabled.

Each colored zone acts as a push button for activating or deactivating thresholds.

" " Threshold action

This section defines the actions to be taken when the value for a performance variable crosses a threshold or zone border. The Threshold action drop-down is used to select a threshold or zone border. The checkboxes identify the actions that can be taken:

" " Add an entry to the Alert Center.
" " Issue a warning beep.
" " Have a program or script start. The program is identified in the field to the right of the Start script action. Available scripts are listed in the Script Center. Select a script from the Select script window.
" " Have a message sent to the user. Enter an appropriate message in the input window below the User message action.

" " Perform action

This section defines when the defined actions take place. The radio button selections are:

" " Whenever a threshold or zone border is crossed.
" " When a threshold or zone border has been crossed a defined number of times. Use the up and down arrows to spin through the available choices.
