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 Control Center from the left main navigation menu and select Usage.
- The Policy Evaluation Usage page is displayed.
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.
Total PE Consumed
The Total PE Consumed section displays:
- The total number of PEs used
- The percentage increase or decrease compared to the previous period
This gives a quick summary of overall usage trends.
Breakdown by Type
The Breakdown by Type table shows PE consumption by policy type for the selected time period.
Each row includes:
- Policy Type
- PE Usage
- Percentage of Total Usage
- Trend (last 7 days)
This helps identify which policy types contribute most to PE consumption.
Download Audit Report
You can download a summary of PE usage as a PDF.
The Audit Report includes:
- Total PEs consumed during the selected date range
- A summary of policy activity
To download:
- Click Audit Report.
- Select a From date and a To date.
- Click Download PDF. The PDF is download to your system.
FAQs
Does each rule within a policy count as a separate PE?
Are PEs counted if a policy fails to execute?
Can I export PE usage data?
Optimizing PE Usage
To manage and optimize PE consumption:
- Review the number of rules in your policies
- Limit large-scale scans when not necessary
- Avoid redundant or overlapping policies
- Review scheduled policy frequency
Monitoring the Breakdown by Type table can help identify high-usage policy categories.
