[jboss-jira] [JBoss JIRA] (AS7-4043) Expose additional web subsystem metrics

    [ https://issues.jboss.org/browse/AS7-4043?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12673885#comment-12673885 ] 

Remy Maucherat commented on AS7-4043:
-------------------------------------

I won't add statistics for the internal pool, which would then conflict with the statistics of an executor when configured. Use an executor (hopefully the thread pools have some statistics).

Having session manager statistics is a reasonable request.

> A user has requested that some further web subsystem metrics be exposed via the management interface:
> "When we run JVM with "-Dorg.apache.tomcat.util.ENABLE_MODELER=true"
> option, we can get currentThreadsBusy via JMX.
> e.g.
>  ObjectName poolObjName = new
> ObjectName("jboss.web:type=ThreadPool,name=ajp-0.0.0.0-0.0.0.0-8009");
>  ajpCurrentThreadsBusy = ((Integer) pfServer.getAttribute(poolObjName,
> "currentThreadsBusy")).intValue();
> It is nice if we could get the information via CLI like:
>  /subsystem=web/connector=ajp13:read-attribute(name=current-threads-busy)
> Additionally, We also would like to get activeSessionCount. We can get
> the information via JMX like:
>  ObjectName sessionObjName = new
> ObjectName("jboss.web:type=Manager,path=/tpcw,host=default-host");
>  activeSessions = ((Long) pfServer.getAttribute(sessionObjName,
> "activeSessionCount")).intValue();
> And it is nice if we could get the information with CLI like:
>  /deployment=tpcw.war/subsystem=web/servlet=TPCWServletWithEncoding:read-attribute(name=active-session-count)"
> I don't think the active-session-count attribute belongs under the "servlet" resource though, since sessions are not associated with servlets. A new resource for the session manager would be needed.
