Policy Evaluation Usage

Policy Evaluations (PE) Usage helps you understand how often governance policies run in your environment. Each time a policy rule runs successfully on your data, it generates Policy Evaluations (PEs).

PE Usage:

Shows how frequently policies are executed
Helps you monitor governance activity
Forms the basis for usage-based billing

The PE Usage page provides a clear view of how PEs are consumed across time and policy types.

What Is a Policy Evaluation (PE)?

A Policy Evaluation (PE) is recorded when: One rule runs successfully on one data entity.

What is a data entity?

A data entity is the smallest unit a policy evaluates. It can be:

A row in a database table or file
A record in a stream or queue
An element in a pipeline

How PE Counting Works

PEs are calculated using simple rules:

Rules	Examples
One rule × one data entity = one PE	If one rule runs on 10 million rows → 10 million PEs
Multiple rules are counted separately	If 3 rules run on 1 row → 3 PEs If 3 rules run on 1,000 rows → 3,000 PEs
Each execution is counted	If a policy runs multiple times (for example, in scheduled pipelines), each successful run generates PEs.
Only successful executions are counted	PEs are recorded only when a policy executes successfully — regardless of whether the result is pass or fail. If a policy fails to execute, no PEs are counted.

PE Calculation by Policy Type

Policy Type	How PEs are Calculated
Data Quality	Rows scanned × Number of rules
Reconciliation - Row Count	1 PE per execution
Reconciliation - Equality	Rows scanned × Number of rules
Data Cadence (Freshness)	Number of rules
Data Drift	Rows profiled × Number of rules
Data Anomaly	Rows profiled × Number of selected columns
Schema Drift	1 PE per execution
Composite	Counted within Data Quality rules
Auto Anomaly	Rows scanned
Pipeline Policy	1 PE per execution

Why PE Usage Matters?

PE Usage helps you:

Understand Your Usage: See exactly how often policies run and how many PEs are generated.
Monitor Governance Activity: Track enforcement across datasets, pipelines, and systems.
Forecast and Manage Costs: Since billing is based on PEs, usage visibility helps you plan and optimize.
Reconcile Billing with Activity: Match PE consumption with actual policy execution patterns.

Accessing PE Usage Page

To access the PE Usage page:

Navigate to the Settings page from the main navigation menu.
Select PE Usage under the Usage category.

Understanding the PE Usage Page

The PE Usage page includes the following sections:

Usage By Time

The Usage By Time chart shows PE consumption for the selected time range.

You can select:

Weekly
Monthly
Yearly
Custom

To compare periods (for example, this week vs. last week), enable the Day Over Day option. This allows you to compare the current period with the previous period.
