There are a couple different ways to determine what the correct query parameters are.
#1 – Run your command and parse through the JSON that is returned. The JSON will show you exactly what element(s) you can query on.
Example: aws ec2 describe-instances –query ‘Reservations[*].Instances[*].[InstanceId, Monitoring.State]’ –output table
#2 – Review the AWS CLI documentation. (e.g. describe-instance-status) On this page you will want to examine the “Output” section, which gives you the same information as #1, but with a different view.
Example: aws describe-instance-status –query ‘InstanceStatuses[*].AvailabilityZone’ –output table
Overall using the query option is pretty easy and at the same time pretty powerful!
