It’s common for users to configure alerts when sensor inputs drift beyond limits on Telemetry2U. Alerts events can be used to send e-mail, SMS or voice notifications as well as trigger actions that can be used of automation or controlling the outputs of other devices.
In certain applications, like cold storage temperature monitoring in hospitals and laboratories that may be required to meet standards according to NATA, NIST, FDA or TGA, every alert event must be recorded and explained.
Adding annotations to alert events on the T2U IoT Platform is easy, and annotations can be reviewed in multiple ways. This bulletin will cover how to both add and review annotations.
- A fully configured account onTelemetry2U's IoT Platform.
- The Add Annotations role assigned in the User Access settings found on the User Maintenance page.
Adding Annotations to Alert Conditions
You can easily see when a senor is in an alert condition on the Dashboard, Chart or Reports pages, but you can only add annotations to alert conditions on the Reports page. The reports page is colour coded so you can easily see when an alert condition has occurred.
An orange background on a record indicates that the node has a sensor input that has triggered an alert condition, but has not yet had enough 'Consecutive Readings' to trigger any notifications.
A Red background on a record indicates that the node has a sensor input that has triggered an alert condition enough times in a row to exceed the 'Consecutive Readings' setting and notifications have been sent.
A Green background on a record indicates that the node has has recovered from an alert condition.
If the user has the Add Annotations role assigned in their User Access settings, the below warning icons will also be visible on any row where an alert condition was triggered. Clicking on these icons will bring up a new page where the annotations can be added and recorded.
The Yellow warning icon is always on the Red background and indicates that a sensor has gone into alert. Click on the Icon to leave an annotation.
The Green warning icon is always on the Green background and indicates that a sensor has recovered from an alert. Click on the Icon to leave an annotation.
The annotation page will show the time the alert event was triggered as well as a summary of what notification where sent. Enter any details about the alert in the Annotation field and hit the Save button.
Viewing Annotations in Audit Reports
The best way to view a summary of all annotations for any particular node is in an Audit Report. If the Audt report has been configured to Include Annotations, you'll see a date/time ordered list of the annotations for that node below the chart.
Audit Reports can only be modified by users who have been assigned the Audit Admin role in their User Access settings.
For more information on creating and editing Audit reports, please refer to Section 5.0 - Audit Reports in our documentation.
