9.5. Alerting on JBoss EAP 6 Resources
Alerting is covered in detail in the alerting and notifications chapters of "Setting up Monitoring, Alerts, and Operations", and that is the best reference for details on planning what alert conditions to set and how to respond.
The key thing in planning alerts is planning automatic responses to whatever condition triggered the alert. For example, within an EAP 6 domain, one managed server may go offline or begin exhibiting extremely slow response times. In that case, JBoss ON can automatically create a new managed server instance, within the same server group, on another platform to take the failing server's place.
Taking an immediate response, without necessarily requiring administrator intervention, is invaluable for customer-facing problems, such as poor response times for a web application.
There are several types of responses that JBoss ON can take:
- Email an administrator
- Run a restart operation on the alerting resource
- Run an operation on the parent of the alerting resource
- Run a shell script
- Run a JBoss ON server-side scriptServer-side scripts are extremely powerful. A script can perform almost any management task in JBoss ON: change resource configuration, deploy updated packages, create new resources, delete existing resources, run an operation, or all of the above. For more information on writing server-side scripts, see "Writing JBoss ON Command-Line Scripts".
