Can single grpc connection be used to receive data from multiple switches?

[stangedas]

I am able to subscribe to data on a single switch with arista gnmi client. Below is the command used to get some data from switch. So this is essentially one to one connection.

gnmi -addr xx.xx.xx.xx:xxxx -username admin -password password get '/components/component'.

Can i use the same connection and add more switch ip's to receive more data? I would like to give string of switch ip's to receive same data from all the devices.

The gnmi client provided here does not allow connecting to multiple switches at once.

Though, this is very doable using the libraries provided here to write a new client.

            go gnmi.Subscribe(ctx, client, subscribeOptions, respChan, errChan)
            for {
                select {
                case resp, open := <-respChan:
                    if !open {
                        return
                    }
                    if err := gnmi.LogSubscribeResponse(resp); err != nil {
                        glog.Fatal(err)
                    }
                case err := <-errChan:
                    glog.Fatal(err)
                }
            }

This is what gnmi does to start a subscription to one client. You could tack on extra calls to Subscribe and emit the output in a way that you like, eg. prefix each line with a name of the device you are connecting to.
