Additionally, you can specify the instructions to be included in email notifications sent to recipients and in the alert message displayed in the Manage->Alerting->Alerts. It is important to note that if high bursts of messages occur regularly (e.g., during nightly batch processing, 1000 messages are expected to be produced to a certain queue), then setting a higher threshold (e.g., 1000 Max messages queued) can prevent false-positive alerts caused by the default configuration. ... ... @@ -52,8 +52,8 @@ 52 52 * **Periodic activity check** 53 53 [[image:Main.Images.Microlearning.WebHome@novice-alerting-customize-queue-alerting-periodic-activity-check.png]] 54 54 This trigger checks whether at least the specified number of messages is received during the specified interval.

Additionally, you will notice that the "Settings" status of the queue trigger you just customized has changed from "Default" to "Custom".
