Overview
Web applications deployed as part of a WAR deployment in JBoss are automatically instrumented to expose relevant runtime JMX statistics on the JMX bus and in CLI. These statistics refer mostly to HTTP session (created sessions, max active sessions, expired sessions, session maximum and average alive time), but other information such as the virtual host or the context root is exposed.
If the web application is clustered (declared <distributable>), the CLI/JMX session metric are cluster-wide metrics. For example, active session refers to the number of active sessions across the entire cluster.
JMX
The web application metrics are available under the following ObjectName:
jboss.as:deployment=<deployment-name>,subsystem=web
where <deployment-name> is the name of the deployment artifact (for example: myapp.war).
CLI
[standalone@ip-address:9999 /] /deployment=${deployment-name}/subsystem=web:read-attribute(name=active-sessions)
