Synopsis
Health Checks determine whether instances are responsive and able to do work.
They are an important part of a comprehensive load balancing configuration, as they enable monitoring instances behind load balancers.
Health Checks poll instances at a specified interval. Instances that do not respond successfully to some number of probes in a row are marked as unhealthy. No new connections are sent to unhealthy instances, though existing connections will continue. The health check will continue to poll unhealthy instances. If an instance later responds successfully to some number of consecutive probes, it is marked healthy again and can receive new connections.
Requirements
The below requirements are needed on the host that executes this module.

Specifies which Ansible environment you’re running this module within. This should not be set unless you know what you’re doing. This only alters the User Agent string for any API requests. |
|
A nested object resource. |
|
The gRPC service name for the health check. The value of grpcServiceName has the following meanings by convention: * Empty serviceName means the overall status of all services at the backend. * Non-empty serviceName means the health of that gRPC service, as defined by the owner of the service. The grpcServiceName can only be ASCII. |
