+### gRPC Health Check
+
+gRPC health checks use the same host and port behavior as `http` and `tcp`
+checks, but gRPC checks also have an optional gRPC service to health check. Not
+all gRPC applications require a service to health check. gRPC health checks
+require Consul 1.0.5 or later.
+
+```hcl
+service {
+  check {
+    type            = "grpc"
+    port            = "rpc"
+    interval        = "5s"
+    timeout         = "2s"
+    grpc_service    = "grpc.health.v1.Health"
+    grpc_use_tls    = true
+    tls_skip_verify = true
+  }
+}
+```
+
+This check would translate to having a Consul check registration with the
+[GRPC][consul_grpc] parameter similar to `10.0.3.1:4567/grpc.health.v1.Health`.
