.. _config_http_conn_man_runtime: Runtime ======= The HTTP connection manager supports the following runtime settings: .. _config_http_conn_man_runtime_represent_ipv4_remote_address_as_ipv4_mapped_ipv6: http_connection_manager.represent_ipv4_remote_address_as_ipv4_mapped_ipv6 % of requests with a remote address that will have their IPv4 address mapped to IPv6. Defaults to 0. :ref:`use_remote_address ` must also be enabled. See :ref:`represent_ipv4_remote_address_as_ipv4_mapped_ipv6 ` for more details. .. _config_http_conn_man_runtime_client_enabled: tracing.client_enabled % of requests that will be force traced if the :ref:`config_http_conn_man_headers_x-client-trace-id` header is set. Defaults to 100. .. _config_http_conn_man_runtime_global_enabled: tracing.global_enabled % of requests that will be traced after all other checks have been applied (force tracing, sampling, etc.). Defaults to 100. .. _config_http_conn_man_runtime_random_sampling: tracing.random_sampling % of requests that will be randomly traced. See :ref:`here ` for more information. This runtime control is specified in the range 0-10000 and defaults to 10000. Thus, trace sampling can be specified in 0.01% increments.
