OPA Dashboard
Monitor OPA enforcement metrics - decision trends, match rates, tool usage, and enforcement action distribution.
Overview
The OPA Dashboard at /dashboard/opa-dashboard provides real-time analytics on how the OPA engine is evaluating and enforcing policy decisions.
Period Selector
Use the period selector in the header to choose the time range: 24 hours, 7 days, or 30 days.
Status Card
The OPA Status Card shows the current engine state:
| Field | Description |
|---|---|
| Health | Whether OPA is reachable and healthy |
| Mode | Current enforcement mode: enforce, shadow, or disabled |
| External URL | The OPA endpoint URL (if using an external OPA instance) |
Metrics Cards
Four key metrics are displayed as cards:
| Metric | Description |
|---|---|
| Total Decisions | Combined count of native and OPA decisions |
| OPA Evaluated | Number of decisions evaluated by OPA, with percentage of total |
| Match Rate | Alignment between OPA and native decisions. Color-coded: green (95%+), yellow (80%+), red (below 80%) |
| Avg Latency | Average response time comparison - OPA vs. native (in milliseconds) |
Decision Chart
A stacked area chart showing decisions over time:
- Native (gray) - Decisions made by the native engine
- OPA (blue) - Decisions made by OPA
- Fallback (yellow) - Fallback decisions when OPA is unavailable
Hover over any point to see the breakdown for that date.
Decision Table
A table of recent individual decisions showing the decision outcome, timestamp, and details.
Enforcement Chart
A donut chart showing the distribution of enforcement actions:
- Block - Request blocked
- Hold - Request held for review
- Allow_log - Request allowed with logging
- Allow - Request allowed
- Shadow - Decision logged but not enforced
The center of the donut shows the total enforcement count.
Tools Chart
A horizontal bar chart showing per-tool decision breakdown:
- Green bars - Allowed decisions
- Red bars - Denied decisions
Each bar is labeled with the tool name (truncated to 20 characters for display).
