Thresholds selection list.
4. Click Add... to open the Select Threshold window. Select Below 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 Minimum field (or use the arrows in the field to specify) the highest acceptable value
for the selected sensor. This is the value that, if fallen below for greater than the number of
seconds specified in the Time Allowed Below Minimum field, will result in an alert condition.
b. Type in the Time Allowed Below Minimum field (or use the arrows in the field to specify) the
number of seconds that the reported value can fall below the value specified in the Minimum
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:[email protected]”).
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
returned to normal. Default value is 0 (state returns to normal immediately after the measured
value is no longer violating the threshold).
Set an Advanced Schedule for this threshold (optional). By default, all thresholds are assumed to
be enabled 24 hours a day, 7 days a week. However, you can specify that a threshold will be
enabled only during specific time ranges. To set an Advanced Schedule:
a.Click Advanced Schedule.... The Schedule Threshold window opens.
b.By default, all time periods in the schedule are set to Enabled. To disable the threshold for a
currently enabled period of time, highlight the period of time by clicking-and-dragging over the
desired time range, and then click Disable. To enable the threshold for a currently disabled
period of time, highlight the period of time by clicking-and-dragging over the desired time
range, and then click Enable.
Note
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.
