# Hyperledger Fabric v1.4 New Features

  • Operational metrics for Fabric components

  • Health check endpoint

    1. path: /healthz
    * request: GET /healthz
* res: 
  - 200 OK, `{status: 'OK', time: '2019-01-21....'}`
  - 503, Service Unavailable, `{status: 'Service Unavailable', ...}`
    1. path: /metrics
    * request: GET /healthz

    쓸만한듯.

  • Dynamic log levels

  • Private data reconciliation

  • Private data client access control
