.. _config_http_filters_health_check:


健康检查
============

* 健康检查过滤器 :ref:`架构概述 <arch_overview_health_checking_filter>`
* :ref:`v3 API reference <envoy_v3_api_msg_extensions.filters.http.health_check.v3.HealthCheck>`
* 此过滤器通过参数 *envoy.filters.http.health_check* 来配置。

.. note::

  请注意如果调用了管理端点 :ref:`/healthcheck/fail <operations_admin_interface_healthcheck_fail>` ，过滤器将会自动地在健康检查中失败并标示 :ref:`x-envoy-immediate-health-check-fail <config_http_filters_router_x-envoy-immediate-health-check-fail>` 标头。（ :ref:`/healthcheck/ok <operations_admin_interface_healthcheck_ok>` 管理端点可以逆反此行为）。
