EAP 7 - Jboss-cli not retrieving session metrics

Issue

For session metrics,

[domain@10.10.10.x:9999 /] /host=yyy/server=prod-server-xxx/deployment=xx.war/subsystem=undertow:read-resource(include-runtime=true)
{
  "outcome" => "success",
    "result" => {
        "active-sessions" => 126,
        "context-root" => "/ehr",
        "expired-sessions" => 0,
        "max-active-sessions" => -1,
        "rejected-sessions" => 0,
        "server" => "default-server",
        "session-avg-alive-time" => 0,
        "session-max-alive-time" => 0,
        "sessions-created" => 0,
        "virtual-host" => "default-host",

• I see max-active-sessions as -1.
• I see "active-sessions" => 126, but "sessions-created" => 0. how is that possible?
• I would like to see session max-alive time.
  "session-max-alive-time" => 0, but i see that as 0.
