The Alert Threshold and Triggers section of the Create New Alert window defines the type of monitored activity (Alert type), Minimum and Maximum (threshold criteria), and Time period for the alert.
In this article:
Basics
To complete the Threshold & Trigger info section:
- Click the Alert type drop-down menu. See Alert Types for information on the alert types supported by the portal.
- Enter a Minimum or Maximum value for the threshold parameter .
For example, to detect if a device exceeds a specific amount of packet data usage, enter a maximum value and leave the minimum value blank.
Notes:
- The user is required to enter only one threshold parameter. Both a minimum and maximum value are not required, therefore leaving a threshold blank is valid.
- If specifying both minimum and maximum values, ensure that the minimum value does not exceed the maximum value.
- Specifying a minimum threshold of one (1) could generate unnecessary email traffic.
- Specifying a threshold value of zero (0) will result in an error.
- Indicate a Time period:
-
Per Hour: Time period between
:00and:59. The period resets at the beginning of each hour. -
Per Day: Time period between
00:00and23:59GMT of one calendar day. - Month to Date: Time period between the 1st of the month and today.
Device activity is tracked from the time the alert is created.
Note: Time periods are based on Greenwich Mean Time (GMT).
-
Per Hour: Time period between
Alert Types
The following table describes the alert types supported by the portal.
Warning: Actual consumed packet data may exceed the amount specified by the Alerts data blocking threshold. Alerts actions such as blocking depend on the frequency that data usage records are available, therefore it is possible for a device to consume more data than is specified by the Alerts threshold. Some products may take as long as 75 minutes for the usage threshold to be detected, during which time the device may continue to consume data:
- For Fusion NA, Fusion Global, and Fusion Global HD products, this period is 11 minutes.
- For Dual-Mode A-LH and Global SIM, this period is 75 minutes.
For more information, see "Alerts-based data blocking" in Alert Limitations.

How Alerts are Processed
When you create an alert, it becomes effective immediately. This means that AerPort immediately begins checking devices to detect if they meet the threshold(s) defined in the alert.
On an hourly basis, AerPort records which devices met the threshold, and then begins applying the traffic policy on the individual devices. An email notification is sent to all users defined in the alert recipient list within 30 minutes.
- If an alert is defined with a Time period of Per Hour, this process repeats hourly. However, once an email notification is sent for a particular device, it is not sent again each hour.
- If an alert is defined with a Time period of Per Day or Per Month, once the alert has been triggered and an email sent, it is not sent again during that period.
- Devices that trigger an alert with a traffic policy will have their services blocked individually. Summary emails to report this activity will be sent every 15 minutes until all device blocking is completed.
- For devices that trigger an alert with no traffic policy, summary emails will be sent every 15 minutes until all devices have been communicated to the email recipients.
Alert Examples
Minimum Threshold Defined
Registration Alert with a minimum count of 1 cellular registration, per hour. An alert will
be generated for a device that registers less than one time in one hour. In other words, if
the device does not register on the network at least once per hour, the alert will be
triggered.
Maximum Threshold Defined
Packet data alert with a maximum threshold of 100 KB, per day. Any Packet data that is
transmitted to or from a device during the day will be totaled. If the total usage exceeds
100 KB at any point during the day, the device will trigger this alert. 
Minimum and Maximum Threshold Defined
Packet Alert with a minimum threshold of 50 KB, or more than 200 KB per day. An alert will
be generated for device(s) that transmit less than 50 KB or more than 200 KB of data in one
day. In other words, any device(s) that transmit between 50 and 200 KB of data per day will
NOT trigger this alert.
