+## keep-alive()

+### max-pings-without-data()
+
+|   Type:|      integer|

+
+*Description:* This option definies the maximum number of gRPC pings that are allowed to be sent when there is no data/header frame. Any pings succeeding this limit are not sent. Setting this option to `0` disables this restriction and keep sending pings.
