# Keepalive



gRPC sends http2 pings on the transport to detect if the connection is down. If

the ping is not acknowledged by the other side within a certain period, the

connection will be close. Note that pings are only necessary when there's no

activity on the connection.



For how to configure keepalive, see

https://godoc.org/google.golang.org/grpc/keepalive for the options.



## What should I set?



It should be sufficient for most users to set [client

parameters](https://godoc.org/google.golang.org/grpc/keepalive) as a [dial

option](https://godoc.org/google.golang.org/grpc#WithKeepaliveParams).



## What will happen?



(The behavior described here is specific for gRPC-go, it might be slightly

different in other languages.)



When there's no activity on a connection (note that an ongoing stream results in

__no activity__ when there's no message being sent), after `Time`, a ping will

be sent by the client and the server will send a ping ack when it gets the ping.

Client will wait for `Timeout`, and check if there's any activity on the

connection during this period (a ping ack is an activity).



## What about server side?



Server has similar `Time` and `Timeout` settings as client. Server can also

configure connection max-age. See [server

parameters](https://godoc.org/google.golang.org/grpc/keepalive#ServerParameters)

for details.



### Enforcement policy



[Enforcement

policy](https://godoc.org/google.golang.org/grpc/keepalive#ServerParameters) is

a special setting on server side to protect server from malicious or misbehaving

clients.



Server sends GOAWAY with ENHANCE_YOUR_CALM and close the connection when bad

behaviors are detected:

 - Client sends too frequent pings

 - Client sends pings when there's no stream and this is disallowed by server
