Hi,

In OmmConsumerClient , what is the callback under which disconnection from ADS can be identified.

In onStatusMsg , onUpdateMsg , onRefreshMsg , this event is not captured.

    Hi @yajnasteju

    EMA internally handles connection events, but doesn't forward them to the client application.

    However, you can indirectly monitor connection activities through the login stream.

    UInt64 loginHandle = consumer.registerClient( ReqMsg().domainType( MMT_LOGIN ).name( "user" ), client, closure );

    Application will receive channel down status (via onStatusMsg) from login stream when there is a disconnection.

    I have logged each message under status message , but Disconnection to ADS is not logged , but , few messages such as - 'Service to the item was lost ' are logged for individual ric codes.

    Have you registered for login stream yet?

    If you do, then there should be channel down events when there is a disconnection.

    StatusMsg
        streamId="1"
        domain="Login Domain"
        ClearCache
        state="Open / Suspect / None / 'channel down'"
        name="u0160375"
        nameType="1"
    StatusMsgEnd


    StatusMsg
        streamId="1"
        domain="Login Domain"
        state="Open / Suspect / None / 'Channel is down.'"
    StatusMsgEnd

    Note that the status is on "Login Domain". They will show up only when you register for login domain events.
