Tealeaf uses alerts to help you monitor event activities. Notifications about alerts are sent in an email. Alerts are created and monitored by the Alert manager.

Alert notifications are based on:

• Event
• Alert type
• Threshold operator, greater than, less than, or in the range of the Threshold value
• The time between alerts notifications

To learn all about alerts and the alert manager, visit our Alert Manager course in our Acoustic Academy. 

Types of alerts

You can create the following types of alerts:

• Average: This alert notification is based on the average of a numeric event value that is collected during the alert interval, based on the threshold value using the threshold operator.
• Count: This alert notification is based on the event count, as compared to the threshold operator and value. Select this option to create an alert that is based on counting a single event.
• Maximum: This alert notification is sent when the numeric event value exceeds the defined maximum during the alert interval, based on the threshold value using the threshold operator.
• Minimum: This alert notification is sent when the numeric event value exceeds the defined minimum during the alert interval, based on the threshold value using the threshold operator.
• Ratio: This alert notification is based on the ratio of two events. You choose two events, one as the denominator and the other as the numerator. The alert notification is sent when the threshold is met. The threshold is set as a percentage.
• Sum: This alert notification is based on the sum of a numeric event value that is collected during the alert interval, based on the threshold value using the threshold operator.

Example

Let's say you create an Alert at 8:00 AM and set Threshold is met within to 10 minutes and Resume alert processing to 5 minutes. In this scenario, the alert is checked every minute after 08:10 AM.

If the Alert is triggered at 08:13 AM, the Alert does nothing between 08:13 AM and 08:18 AM. At 08:18 the Alert resumes processing and is checked every minute after 08:28 AM, as 08:28 AM marks the 10-minute interval.

Update alerts

You can manage your alerts in the Alert Manager by selecting My alerts. Users assigned the Administrator role can manage all Alerts by selecting All alerts. You can also manage Anomaly detection alerts from the Alert Manager.

Regular users can monitor the alerts that they created, and any alert that is shared with them by clicking the alert name to view the alert details. Regular users and the Administrator can also create copies of alerts, change the alert criteria, stop alert notifications, reset alerts, and remove alerts.

The administrator can manage all Alerts across the organization (whether the Alert was shared with them or not), by clicking the alert name to view the alert details.

• You can use existing alerts as templates for new alerts by creating a copy of the alert:
  1. Select the alert that you want to create a copy of.

• If you want an alert to remain active but do not wish to receive notifications, you can set the Watching toggle to off. This will remove alerts from the Alert manager without deleting them. 

  Note: You can enable/disable alerts that you created or alerts that are shared with you. Deleting an alert removes the alert from your view, from the Alert manager of anyone you shared the alert with, and from the system. Turning a watched alert off turns the alert off from your watched list, but the alert remains in the system.
