1. Please describe the issue you observed:

   • What did you do (The steps to reproduce)?
     I used trace example to produce and consume messages.
   • What did you expect to see?
     Check the message trace on console and find the correct storeHost and groupName
   • What did you see instead?
     The response as follows , the storeHost is the console host, not the client host; the groupName in SubAfter message is empty

    "status":0,
    "data":[
        {
            "msgId":"0AE830DD4A4F0000000011b799480001",
            "tags":"",
            "keys":"null",
            "storeHost":"xxx",
            "costTime":0,
            "msgType":"SubBefore",
            "offSetMsgId":"",
            "timeStamp":1609754334084,
            "topic":"",
            "groupName":"zx_tst",
