keepAliveWithoutCalls

var keepAliveWithoutCalls: Boolean(source)

If true, the Agent sends gRPC keepalive pings to the Proxy even when no RPCs are in-flight — useful when the connection traverses a load balancer or NAT that idles out silent TCP sessions. The Proxy must permit this via --permit_keepalive_without_calls or it will reject the pings as a protocol violation.
