You can measure your Reserved Instance usage within the Cloudability app using data accessible through Reports and Widgets.
In this section, we'll cover:
There are three Reserved Instance data metrics available in Cloudability.
Reserved Hours: The number of hours paid at a reserved rate on a given day.
On Demand Hours: The number of hours paid on-demand on a given day.
Reserved Utilization Rate: The percentage of your infrastructure covered by Reserved Instances on a given day.
You can report on the Reserved Instance metrics available to you in Cloudability using our Cost Analytics feature. One common way to do this is with a Reserved Utilization report.
Build a new Cost Report and customize the report with “Reserved Hours,” “On Demand Hours,” and “Reserved Utilization Rate” as the Metrics, and “Usage Type” and “Item Description” as the Dimensions. Then, add the filters “Item Description does not contain hours used” and “Usage Type contains usage.”
The report will display a graphical and numerical breakdown of your total usage hours within a time period of your choice. The graphical aspect will display what percentage of your infrastructure was billed at a reserved rate on any given day, and how that’s trended over time. Below the graph, you can see the specific numbers on how many of your usage hours were paid at a reserved rate, and how many were paid On-Demand. Does the coverage match your expectations? If not, it’s time to go deeper.
You can drill into which aspects of your infrastructure have the most and least Reserved Instance coverage as differentiated by the “Usage Type” dimension, displayed on the bottom section of the page.
To see the items with the lowest RI coverage, filter by Reserved Utilization Rate. These are the areas that were either overlooked in your RI planning, or that aren’t using the reservations you’d planned for them.
You can also use these Reserved Instance metrics to create widgets for your dashboard. One way to do this is with a "reserved hours vs. on-demand hours" widget.
To build a “Reserved hours vs. on-demand hours” widget for your Cloudability Dashboard, add a new widget with an “Area” layer that has “Usage Hours” as the Metric and “Date” as the Dimension. Add a “Line” layer with “On Demand Hours” as the Metric and “Date” as the Dimension, then one more “Line” layer with “Reserved Utilization Rate” as the Metric. Then, add the filters “Item Description does not contain Hours Used,” and “Product Name contains Compute.”
