Incorrect value returned by undertow for "max number of concurrent active sessions" metric

      1. Deploy [^helloworld.war] file.
      2. Connect to server using CLI (jboss-cli.sh)
      3. Request the metric: /deployment=helloworld.war/subsystem=undertow:read-attribute(name=max-active-sessions)

      The server is returning:

      [standalone@localhost:9990 /] /deployment=helloworld.war/subsystem=undertow:read-attribute(name=max-active-sessions)
      {
          "outcome" => "success",
          "result" => -1
      }
      

      The server is returning -1 because this is the default value for unlimited sessions. If you deploy [^helloworld2.war] file, the server returns 2 for that deployment, this is the maximum allowed session configured in the war file. (jboss-web.xml max-active-sessions).

      [standalone@localhost:9990 /] /deployment=helloworld2.war/subsystem=undertow:read-attribute(name=max-active-sessions)
      {
          "outcome" => "success",
          "result" => 2
      }
      

      This is not the maximum number of concurrent sessions metric that we expected.

    Description

      Undertow is returning "maximum active sessions allowed" configured in the deployment as the "max number of concurrent active sessions" metric.

      Additional Information:

      I requested a resource description and the description of the attribute says it is a metric.

      [standalone@localhost:9990 /] /deployment=helloworld2.war/subsystem=undertow:read-resource-description 
      .......
      .......
      
                  "max-active-sessions" => {
                      "type" => INT,
                      "description" => "*Max number of concurrent active sessions*",
                      "expressions-allowed" => false,
                      "nillable" => false,
                      "access-type" => "metric",
                      "storage" => "runtime"
                  },
