Getting Target that client connected to

[mica...@seas.upenn.edu]

Hi, I would like to just obtain the information of the server I connected to here is how my functionality is being used:

ProjectGuideClient client(grpc::CreateChannel(server,grpc::InsecureChannelCredentials()));

client.Dele(args);

If I return back a not ok status I would like to connect to a master node and retrieve the back up server to connect to. To do this I need to send the server that I want the back up to. In this case I need to obtain the variable "server" as shown in above. where can I access this information? and how. below there are questions marks of how I would to use it and I thought I could get the information? Thanks!!

/*

 Dele rpc command

 Parms string row, string col

 Returns true if deleted, false if an error

 */

bool ProjectGuideClient::Dele(DeleArgs args) {

DeleResponse response;

ClientContext context;

Status status = stub_->Dele(&context, args, &response);

  if(status.ok())

return status.ok();

  else{

    //get my channel to senda rewuest for backup

my channel = "Channel.Target(); ???????

  }

}

gRPC does not return the target name (this is something the user/application should keep track of when creating the channel).

however, the ClientContext::Peer() would return you the address of the exact backend the Call went to..
