      • getEnableDispatcherStats

        public boolean getEnableDispatcherStats()
         Enable :ref:`stats for event dispatcher <operations_performance>`, defaults to false.
 Note that this records a value for each iteration of the event loop on every thread. This
 should normally be minimal overhead, but when using
 :ref:`statsd <envoy_api_msg_config.metrics.v2.StatsdSink>`, it will send each observed value
 over the wire individually because the statsd protocol doesn't have any way to represent a
 histogram summary. Be aware that this can be a very large volume of data.

 transformed into x-foo-retry-on etc.
 Note this applies to the headers Envoy will generate, the headers Envoy will sanitize, and the
 headers Envoy will trust for core code and core extensions only. Be VERY careful making
 changes to this string, especially in multi-layer Envoy deployments or deployments using
 extensions which are not upstream.
        string header_prefix = 18;

      • getUseTcpForDnsLookups

        public boolean getUseTcpForDnsLookups()
         Always use TCP queries instead of UDP queries for DNS lookups.
 This may be overridden on a per-cluster basis in cds_config,
 when :ref:`dns_resolvers <envoy_api_field_Cluster.dns_resolvers>` and
 :ref:`use_tcp_for_dns_lookups <envoy_api_field_Cluster.use_tcp_for_dns_lookups>` are
 specified.
 Setting this value causes failure if the
 ``envoy.restart_features.use_apple_api_for_dns_lookups`` runtime value is true during
 server startup. Apple' API only uses UDP for DNS resolution.
        bool use_tcp_for_dns_lookups = 20;
