Examples of com.amazonaws.services.ec2.AmazonEC2.describeInstances()

com.amazonaws.services.ec2.AmazonEC2.describeInstances()

Describes one or more of your instances.

If you specify one or more instance IDs, Amazon EC2 returns information for those instances. If you do not specify instance IDs, Amazon EC2 returns information for all relevant instances. If you specify an instance ID that is not valid, an error is returned. If you specify an instance that you do not own, it is not included in the returned results.

Recently terminated instances might appear in the returned results. This interval is usually less than one hour.

@param describeInstancesRequest Container for the necessary parametersto execute the DescribeInstances service method on AmazonEC2. @return The response from the DescribeInstances service method, asreturned by AmazonEC2. @throws AmazonClientException If any internal errors are encountered inside the client while attempting to make the request or handle the response. For example if a network connection is not available. @throws AmazonServiceException If an error response is returned by AmazonEC2 indicating either a problem with the data in the request, or a server side issue.
