Thrift Health Checker

The Thrift Health Checker (with envoy.health_checkers.thrift as name) uses Thrift requests, responses and exceptions to check upstream hosts. It sends a request with method_name and expects a success response in exchange. The upstream host can also respond with an exception to cause the check to fail. The transport and protocol types to be set for each health check request must be configured to enable Thrift health checks. The sequence id is always 0 for each health check request.

An example for custom_health_check using the Thrift health checker is shown below:

  name: envoy.health_checkers.thrift
      method_name: ping
      transport: HEADER
      protocol: BINARY
