#get_health(instance_name = nil) ⇒ Object

Get most recent health checks for each IP for instances.

Example Hash: 

"https://www.googleapis.com/compute/v1/projects/myproject/zones/us-central1-f/instances/myinstance"=>

[{:health_state=>“UNHEALTHY”,

:instance=>"https://www.googleapis.com/compute/v1/projects/myproject/zones/us-central1-f/instances/myinstance"

] }

Parameters:

  • instance_name (String) (defaults to: nil) —

    a specific instance to look up. Default behavior returns health checks for all instances associated with this check.
