Designed for system administrators, the OpenEdge HealthScanner checks the overall health of a server assigning a score from 0-100% as well as a status code. System Administrators configure an acceptable threshold for a server to be considered in operational good health. Servers with scores below the threshold can be taken out of service by an elastic load balancer (ELB). The ELB can terminate the server and dynamically replace the failing server before any disruption of service is incurred.

The following is an example of the AWS (Amazon Web Service Cloud) Health Check configuration for a server that is part of an auto scaling group. Use the AWS Health Check ping target field to poll the health.

If the ping returns a status code of 500, then the server is automatically terminated, and the new server is brought online providing continuous availability of a healthy server to respond to client requests.

Note: The HealthScanner is limited to cloud operating systems for Windows and Linux.
