InterSystems: The power behind what matters   

This chapter describes how to configure a production to alert users about important events, such as events that require user intervention. It includes the following sections:
About Alerts
An alert sends notifications to applicable users while a production is running, in the event that an alert event occurs. The intention is to alert a system administrator or service technician to the presence of a problem. Alerts may be delivered via email, text pager, or another mechanism.
The alert mechanism works as follows:
All alerts also write messages to the InterSystems IRIS Event Log, with the type Alert. See Monitoring Productions for details.
Configuring an Alert Processor
Each time any alert is sent, the alert text is added to the Event Log. This mechanism might be too passive for the most urgent messages. If you want the production to also actively seek the user, you must define and configure a business host that has the ability to contact a user device. This business host is known as an alert processor or an alert target.
To add the alert processor to the production:
  1. Add the business host class to the production. This class is a business operation or business process class, depending on its implementation.
  2. For the configuration name, specify Ens.Alert
  3. If the alert processor has settings such as email addresses and telephone numbers, configure those.
  4. Add any business services that the alert processor calls.
Any production can include no more than one alert processor.
Configuring Alerts on Errors
InterSystems IRIS can send alerts automatically whenever a business host encounters an error condition. The Alert On Error setting controls this behavior. If Alert On Error is True, then whenever the business host encounters an error, InterSystems IRIS triggers an alert.
Note that business hosts provide an optional grace period that enables the business host to retry before triggering the alert. Depending on the kind of business host, this grace period is specified by the setting Alert Grace Period or Alert Retry Grace Period.
Configuring Alerts on Queue Buildups
InterSystems IRIS can send alerts when a business host’s queue has too many messages or has messages that have waited too long. To enable these alerts, specify the following settings with nonzero values:
Other System Alerts
InterSystems IRIS generates alerts on other occasions, including the following:
