APC NetBotz 320 Rack Appliance NBRK0320E User Manual

An above value for time threshold is defined by specifying a maximum acceptable value for the sensor 
and a maximum period of time value. If the value reported by the sensor exceeds the specified value for 
more than the specified period of time an alert condition is reported. To define an above value for time 
threshold:

1. Start the Camera Pods, Sensor Pods, or Device Crawlers task by double-clicking on the appropriate 

icon.

2. Click Sensors... to open the Sensor Configuration window.

3. Select from the Sensors selection list the sensor for which you will define a threshold. A list of 

thresholds that have been previously defined for the selected sensor, if any, appears in the 
Thresholds selection list.

4. Click Add... to open the Select Threshold window. Select Above Value for Time Threshold and 

then click OK to close the Select Threshold window.

5. Type in the Threshold Name field a name for this threshold.

6. Specify Basic threshold settings. From the Basic tab in the Thresholds pane:

a. Type in the Maximum field (or use the arrows in the field to specify) the highest acceptable 

value for the selected sensor. This is the value that, if exceeded for greater than the number of 
seconds specified in the Time Allowed Above Maximum field, will result in an alert condition.

b. Type in the Time Allowed Above Maximum field (or use the arrows in the field to specify) the 

number of seconds that the reported value can exceed the value specified in the Maximum field 
before an alert condition is generated.

c. Check the Enabled check box to enable the threshold. If this check box is not checked, the alert 

threshold will be saved but will not be active.

d. Add to the Threshold-Specific Addresses list the e-mail addresses of any personnel to whom e-

mail alert notifications should be sent if this threshold triggers an alert condition. Click Add..., 
type in the e-mail address to which the alert notification will be sent, and then click OK. 

If you’ve installed an SMS-capable modem you can deliver alert notification to SMS-enabled 
devices by entering threshold-specific addresses for them in the following format: 

sms:sms_device_address

where sms_device_address is the telephone number or e-mail address associated with the SMS-
enabled device (for example, “sms:5123334444” or “sms:user@mycorp.com”). 

7. If desired, specify Advanced Threshold settings. All Advanced threshold settings are optional. From 

the Advanced tab in the Thresholds pane:

– Specify a Return To Normal Delay value. Use the controls to specify the number of seconds 

that must pass after this threshold has returned to normal before the threshold state is considered 

These threshold-specific notifications are sent only if your appliance has one or 
more Alert Actions defined that use the Send E-Mail Message alert notification 
method and that have the Include Addresses from Thresholds check box 
checked. For more information, see “Alert Actions” on page 59 and “Advanced 
View: Creating Alert Actions” on page 161.
