Custom Metrics

Overview
Custom metrics allows customers to calculate metrics based on existing attributions within the CMP. Often when reporting on cost and usage for cloud environments the dimensions and metrics in your bill are not sufficient to understand key information. By creating formulas with portions of the bill key indicators of performance can be surfaced more cleanly.
For example:
Percentage of GCP CUD utilized
CUD (committed use discount) Usage / CUD (committed use discount) Commitment
Amortized Instance Reservation Consumption
Monthly Ec2 Instance type usage / (1 yr Reserved Instance type commitment / 12)
Percentage Shared Infrastructure Cost
Shared Infrastructure costs / Total Infrastructure Cost
Custom metrics can be particularly useful when tracking consumption of shared services. Determine what percentage of shared infrastructure is being used by a single app. Determine distribution of compute types across a set of accounts or projects.
Structure of a Metric
Custom metrics are created by creating formula's with Attributions. Each Attribution must have a base metric selected for it. This can either be: Cost, Usage, or Savings. For more information, see our Metric selection documentation.

For instance, if you want to create a metric to track the percentage consumption of a compute commitment, you will require 2 Attributions.
Compute Usage
Compute Consumption.
Please ensure these Attributions are created in advance of metric creation
Create a Metric
Navigate to Cloud Analytics, and select the Metrics tab

Select 'New Metric'

Provide a name for the new Custom Metric.
Select Attribution to set as A
Select 'Base Metric' for Attribution A
Repeat as necessary for required attributions
Create a formula to generate the metric desired.
Formulas
Formulas support standard Order of Operations
Custom metric formulas support the following operators:
Operator
Description
+
Addition
-
Subtraction
*
Multiplication
/
Division
()
Parentheses for grouping
When a valid formula is created it will be automatically saved.
A formula is considered invalid if it is:
1.Empty
2.Invalid Variable Definition
1.Attribution and/or base metric provide no data
2.Variable is not complete (no metric selected, no attribution selected)
3.Invalid Formula
1.Yields an error
2.Divide by zero
3.Incorrect formatting
When a valid formula is complete a preview will generate below
Example metric
GCP N1 Commitment Coverage %
N1 Commitments / N1 Usage as %

Including Customer Metrics in Cloud Analytics Reports
To include a metric in a report, create a new report​​
In the Report configuration panel select 'Metric'
A screenshot of the Metric drop-down menu
Once selected you will be prompted to confirm your choice
A screenshot of the Show N1 Commitment Coverage modal dialog
Once selected you can build your report as normal with the required attributions and run your report
