--------------------------------

             Summary: stats.config.xml was broken by TS-443
                 Key: TS-2175
                 URL: https://issues.apache.org/jira/browse/TS-2175
             Project: Traffic Server
          Issue Type: Bug
          Components: Stats
            Reporter: Yunkai Zhang


stats.config.xml was broken by TS-443.

It's no meaningful to do *recursive* calculation:

{code}
    <statistics
        minimum="0"
        interval="10">
        <destination>proxy.node.user_agent_xacts_per_second</destination>
        <destination scope="cluster">proxy.cluster.user_agent_xacts_per_second</destination>
        <expression>
            proxy.node.http.user_agent_xacts_per_second
        </expression>
    </statistics>
{code}

The *expression*, proxy.node.http.user_agent_xacts_per_second, equals to node *destination*, that is wrong.

This issue will cause the value of "proxy.node.http.user_agent_xacts_per_second" to be zero.

There are other same mistakes caused by TS-443.
