VM::EC2::Instance::StatusItem(3) Object describing a instance status event


@status_items = $ec2->describe_instance_status();
for my $i (@status_items) {
print $i->instance_id,
': instance check=',$i->instance_status,
', system check=',$i->system_status,"\n";
if (my $e = $i->events) {
print $i->instance_id,' event = ',$e;


This object represents an instance status returned by $ec2->describe_instance_status().


These object methods are supported:

 instanceId            -- The ID of the affected instance.
 instance              -- The VM::EC2::Instance object
 availabilityZone      -- The availability zone of this instance.
 events                -- A list of VM::EC2::Instance::Status::Event objects
                           representing a scheduled maintenance events on this
                           instance (see note).
 instanceState         -- The state of this instance (e.g. "running")
 systemStatus          -- A VM::EC2::Instance::Status object indicating the
                            status of the system check.
 instanceStatus        -- A VM::EC2::Instance::Status object indicating the
                            status of the instance availability check.

NOTE: There is an inconsistency in the AWS documentation for this data type. The events field is documented as being a list, but the examples shown return a single object. At release time, I was unable to verify which is correct and have written the code such that it will always return a list, which may be single elementin length.

In a string context, this object will interpolate as:

 "$instanceId: XX/2 tests passed"

where XX is the number of checks that passed.

In the case of an instance that is not running, the interpolation will be:

 "$instanceId: $state"

Where $state is the state of the instance (e.g. ``stopped'').
