VM::EC2::ELB::InstanceState(3) User Contributed Perl Documentation VM::EC2::ELB::InstanceState(3)

VM::EC2::ELB:InstanceState - Object describing the state of an instance attached to a load balancer. It is the result of a DescribeInstanceHealth API call.

 use VM::EC2;
 my $ec2          = VM::EC2->new(...);
 my $lb           = $ec2->describe_load_balancers('my-lb');
 my @instance_ids = map { $_->InstanceId } $lb->Instances();
 my @states       = $lb->describe_instance_health(-instances => \@instance_ids);
 my @down_ids     = map { $_->InstanceId } grep { $_->State eq 'OutOfService' } @states;

This object is used to describe the parameters returned by a DescribeInstanceHealth API call.

The following object methods are supported:
 InstanceId   -- The Instance ID of the instance attached to the load balancer
 State        -- Specifies the current status of the instance
 ReasonCode   -- Provides information about the cause of OutOfService instances.
                 Specifically, it indicates whether the cause is Elastic Load Balancing 
                 or the instance behind the load balancer
 Description  -- Description of why the instance is in the current state
The following convenience methods are supported:
 instance     -- Provides an L<VM::EC2::Instance> object

When used in a string context, this object will interpolate the instance state.
