gRpc sending heartbeat - client/server

Question

I am very new to gRpc and have started exploring their basics(in C#). I would like to get guidance on how we can send heart beats to check if client/server is still connected and take recovery actions in case they are disconnected. Any example or reference to any documents/articles will be helpful to get me started. Thanks!

Answer 1

Have a look at the gRPCHealth Checking Protocol .

It's a straightforward protobuf that describes a mechanism by which a client can check whether a server is available and whether services hosted on the server are healthy. The service includes a Watch method that provides heatbeats.

You could extend eg the Watch method or the HealthCheckRequest message with a periodicity property to provide clients with a way to define the frequency of messages they require.
