Node Health Check

Introduction

• This software guarantees availability of orion transaction manager. The code aims to work hand in hand with the operating system. If for some reason Orion fails then the software restarts orion service.

• Currently this code is being used in the lacchain network by writer nodes that execute private transactions. The installation has been automated in the lacchain-network repository by using ansible.

• When running, the software monitors the following:

  1. Orion Node url

  3. Orion Java process: Monitors the heap and old space.
