Thresholds and Notifications

Custom Thresholds and Real-Time Notifications

Advanced analytics provide operational insights and deep visibility, including trends. Set SMS/email alerts for anomalies based on customizable threshold values and complex rules, setting notification by individual sensors or sensor groups.

Warning Icon in Threshold and Notification Lists

Threshold and notification lists show a yellow warning icon next to incomplete thresholds and notifications with missing assignments of users, measurements, bridges, and/or sensors. This icon will alert the user that additional configuration is needed before the threshold or notification becomes active. Clicking on these lines will display more details about which assignment is missing, guiding users to complete the setup.

Operational Modes with Dynamic Thresholds

Operational modes make it easy to associate multiple thresholds with a sensor’s measurement and automatically switch the active threshold when the operational mode is changed.

This feature is ideal for production lines where sensors need to be reconfigured with different thresholds based on the product being produced. For example, an oven may have a different normal operating range for each product. In this case, each custom operational mode would correspond to a product with unique thresholds. If some products always share the same thresholds, they could be combined under a single operational mode for simplified threshold management.

Another use case for operational modes is the monitoring of environments where thresholds need periodic adjustments based on usage patterns, seasonal changes, or other cyclical factors. In such an environment, each operational mode would correspond to some custom usage mode or a season.

An operational group consists of up to ten custom operational modes including the default mode “None.” An operational group also contains measurements whose thresholds change depending on the active operational mode. Users can configure different thresholds for those measurements in each operational mode.

When an operational mode is activated, measurements from that operational group are assigned the selected thresholds for that operational mode. Color-coded measurement charts, as well as the real-time dashboard and historical analytics, take operational mode history into account to use the appropriate threshold at the appropriate time.

The edit function can be used to fix mistakes if the user forgot to switch operating modes or switched to the wrong operating mode. The edit function can also be used to retroactively back-fill operational mode history even for times before the operational group was created. The operational groups page can be accessed from the thresholds menu in the navbar. There is no limit to the number of operational groups that can be created to handle any dynamic environment.

Composite Notifications

Composite Notifications are useful when users want a combination of several measurements to act together to trigger a notification. A composite notification is sent only if the notification criteria is met for all attached measurements at the same time. To provide flexibility, notification criteria can be set to either abnormal or normal for each attached measurement, and up to four measurements can be attached to each composite notification.

For example, a user may wish to be notified if a cooler temperature is too high because the cooler door was left open. In this case, both cooler temperature and cooler door measurements would be attached to the composite notification with their notification criteria set to abnormal. In other scenarios, users may wish to be notified when some measurements are normal while others are abnormal.

Test Notification

Users can easily test that a measurement or hardware notification is completely setup and that the notification system is working as expected.  The Test Notification page first verifies that setup is complete, and, if necessary, informs the user about missing steps needed to complete setup.  When the bell button is pressed, a test notification is immediately sent to all selected users using all selected delivery methods.  Users can verify that emails from [email protected] are not intercepted by anti-spam filters, and that SMS and voice messages are delivered to their mobile device.  The test can be accessed using the Test Notification button on any notification details page.

Notification History

Notification history provides access to the complete record of all notifications sent in the past. Each sent notification entry provides details about the time the notification was sent, the name of the notification, the name of the target bridge, sensor, or measurement, the measurement value that was recorded at the time, the criteria that triggered the notification, and a list of users that received the notification. The Notification History menu item can be found in the navbar under Notifications.

Browsing by Time Range

Notification history can be browsed by selecting a time range and pressing the blue search button with the magnifying glass icon. On the left of the search button, the gray button with the x icon will reset all filters and return the time range to the default range of the last 30 days.

Filtering by Notification Type

Search results can be filtered by one or more notification types: Measurement, Composite, and Hardware. For example, users can choose to see only Hardware notifications by checking the hardware checkbox. The Select All checkbox toggles all notification types at the same time.

Filtering by Criteria

Search results can be further filtered by one or more notification criteria. To see the list of all available criteria, click on the Notification Type dropdown to show more checkboxes indented under the Measurement and Hardware notification types. For example, users can choose to see only Measurement notifications that were triggered by the criteria High Critical or High Warning.

Filtering by Bridge, Sensor, or Measurement Name

Notification results can be further filtered by searching for any notifications involving bridges, sensors, or measurements whose name contains the given substring. For example, users could search for any notifications involving coolers by entering “cooler” into the Object field.
