Hi Rajesh,

Sorry, I did not understand your case.
In my answers I assumed that for the client was enough to receive the snapshot maintained by the Lightstreamer server without need to involve the adapters and the back-end.

But, actually, it is not entirely clear to me why should be the client to notice the problem with the real-time feed and not the data adapter itself, which could take immediate measures.
In any case the proper way for a client to comunicate with the Adapters is the sendMessage that will be received by your Metadata Adapter.

Regards,
Giuseppe
