The report can either be displayed By Day or By Hour for your selected date range.

Use the Start and End Date boxes at the top of the report if you would like to set a custom date range.  By default the report will show the past 7 days.  Next, choose your filter options.  If you do not choose any options, the report will show hours for all EC2 instances that were running over the selected time range.

The report can be filtered by:

  • AMI – the unique Amazon Machine Image utilized by the instance(s).  Example: ami-000af969
  • Instance ID – the unique ID for the EC2 instance.  Example: i-52928229
  • Region – the geographical location where the instance resides.  Example: US East (Northern Virginia)
  • Resource Tags – the resource tag applied to the EC2 instance(s).  Example: [Key = XXX] [Value = YYY]
  • Instance Type – the size of the EC2 instance(s).  Example: t1.micro

You can add multiple filter options by clicking on the green ‘plus’ symbol (+).  Once you have made your filter selections, click the filter button.
