CORTX ha (High-Availability) is responsible for ensuring that CORTX Solution is available in case of any hardware component or software service failures. It takes care of failover/ failback control flow for affected services and stabilizes them across CORTX cluster.
Implement a health event generator framework python script file which will help to generate a mock event for node and disk
Design
It will be python script file which will have options to get ids. Script file will have following options:
"get disks":
"get cvgs":
"publish":
This script will also provide implementation of these options except publish option
