Chapter 9. Monitoring JBoss EAP 6 Resources

Metrics are a live-stream of information about how a resource or group of resources are performing. Metrics are vital signs, like the heart rate, blood pressure, and oxygen levels for a hospital patient. For resources, those vital statistics are elements like availability, page hits for database caches, or active connections for datasources or web applications. Those metrics show resource health, observed at a specific moment.

The JBoss EAP 6 console shows that current and immediate snapshot of information for a handful of critical metrics for a few critical resources, like datasources, transactions, and web applications.

This changing information is displayed in the Runtime tab of the EAP 6 console.

Runtime information shows the health for that exact moment in time.

Looking at the runtime information over time gives a much better perspective of how a resource is performing, generally. Every resource in JBoss ON has areas to view and configure monitoring and to configure alerting based on that monitoring.

JBoss ON automatically processes runtime metrics in a few different ways, to help administrators process performance data:

JBoss ON also exposes more monitoring data for individual resources through its GUI:
