.. _config_http_filters_health_check: Health check ============ * Health check filter :ref:`architecture overview ` * :ref:`v2 API reference ` * This filter should be configured with the name *envoy.health_check*. .. note:: Note that the filter will automatically fail health checks and set the :ref:`x-envoy-immediate-health-check-fail ` header if the :ref:`/healthcheck/fail ` admin endpoint has been called. (The :ref:`/healthcheck/ok ` admin endpoint reverses this behavior).
