Monitoring the Connection

Managing the interaction with the server is primarily the job of the client library but most of the libraries also provide some insight into what is happening under the covers.

For example, the client library may provide a mechanism to get the connection's current status:

Go

nc, err := nats.Connect("demo.nats.io", nats.Name("API Example"))
if err != nil {
    log.Fatal(err)
}
defer nc.Close()

getStatusTxt := func(nc *nats.Conn) string {
    switch nc.Status() {
    case nats.CONNECTED:
        return "Connected"
    case nats.CLOSED:
        return "Closed"
    default:
        return "Other"
    }
}
log.Printf("The connection is %v\n", getStatusTxt(nc))

nc.Close()

log.Printf("The connection is %v\n", getStatusTxt(nc))
