=head1 NAME

VM::EC2::ELB:HealthCheck - Load Balancer Health Check Parameters

=head1 SYNOPSIS

  use VM::EC2;

  $lb = $ec2->describe_load_balancers('my-lb');
  my $hc                   = $lb->HealthCheck;
  my $interval             = $hc->Interval;
  my $target               = $hc->Target;
  my $healthy_threshold    = $hc->HealthyThreshold;
  my $unhealthy_threshold  = $hc->UnhealthyThreshold;
  my $timeout              = $hc->Timeout;

=head1 DESCRIPTION

This object is used to describe the parameters used to perform
healthchecks on a load balancer. Generally you will not call
this directly, as all its methods are passed through by the
VM::EC2::ELB object returned from the HealthCheck() call.

=head1 METHODS

The following object methods are supported:
 
 Interval           -- The time interval between health checks
 Target             -- The target protocol protocol and port of the check
 HealthyThreshold   -- The number of successive positive health checks that 
                       need to be completed to be marked as healthy
 UnhealthyThreshold -- The number of successive negative health checks that
                       need to be completed to be marked as unhealthy
 Timeout            -- The time interval of what is considered a timeout

=head1 STRING OVERLOADING

When used in a string context, this object will interpolate object
parameters as a series of Key:Value strings
