Report API ML state to the MF System Programmer

[jalel01]

Use Case

As a System Programmer, I want to automate system behavior based on the state of the API Mediation Layer. I want to use WTO to capture the state.

Technical Requirements

• System Automation for z/OS needs to receive a MVS message via the SubSystem Interface to be notified of the UP status
• API ML will generate a WTO when all main services are UP

Notes

• API ML consists of 3 major components, the EUREKA-Discovery Service, API Gateway, and API Catalog. By reporting the state of these components, we enable mainframe admins to control the state of the API ML using popular automation tools.
