Local Health check

You can use health checker to check local service health. When service instance is unhealthy, mesher will update the instance status in registry service to “DOWN” so that other services can not discover this instance. After the service becoming healthy again, mesher will update the status to “UP”, then other instance can discover it again. Currently this function works only when using service center as registry.

Examples:

• Check local http service

      uri: /health
