Hi,

I'm using ovsdb-server of openvswitch 2.1.0<http://openvswitch.org/releases/openvswitch-2.1.0.tar.gz> version with VTEP schema. I see the following issues:


1.      Unable to use multiple times "Monitor" request for the same table.

*        First time,  when I sent "Monitor" request for Manager table, it is success.
                              Request-> ["hardware_vtep",null,{"Global":{"columns":["managers"]},"Manager":{"columns":["target"]}}]

Response -> {"id":"100","result":{},"error":null}



*        Second time, when I sent "Monitor" request for Manager table with same/different "id" and I got the following "duplicate monitor ID" error.

Request-> ["hardware_vtep",null,{"Global":{"columns":["managers"]},"Manager":{"columns":["target"]}}]

Response -> {"id":"101","result":{"error":"syntax error","details":"duplicate monitor ID","syntax":"null"},"error":null}

I have opened TCP connection and send the multiple "Monitor" requests. Why it is not possible to send multiple times of "Monitor" protocol for the same table and on the same connection?


2.      "Monitor Cancel" operation is not all working after "Monitor" request is sent and getting the "invalid parameters" error.

Request-> ["hardware_vtep",null,{"Global":{"columns":["managers"]},"Manager":{"columns":["target"]}}]

monitor cancel response-> {"id":"103","error":"invalid parameters"}



3.      How to get the current table data without using "Monitor" request? Because I'm unable to use multiple times of "Monitor" request as mentioned in point 1 and also I will get notification for rows I created. Is it possible to read the tables data of OVSDB-Server without using "Monitor" request?

Please let me know.

Thanks,
Sudheer
