Vault status ouptut - how is it derived?

Introduction

This article helps understand how the vault status output is derived. 

• There are several calls from Vault to various functions in the code that will combine that information in to the status output.
• The Active Node address value will return the information for the specific active node you are on
• For the HA Cluster value, it is created from cluster_addr and would return the value set there
• There is a much deeper rabbit hole to go down in the code as far as how various items are retrieved, but the bulk of the actions are handled from the endpoint given to the VAULT_ADDR
