Delivery Format Dashboard
Web Assets / DeliveryVisualize delivery format ratios and device failure rates entirely in-browser, ready to trigger fallbacks when thresholds are breached.
Plot delivery format share and device-level failure rates before rollout changes hit production.
Model device-format telemetry and watch failure rates update instantly.
Delivery entries
Fallback fires when failure rate ≥ 1%.| Device / Surface | Format | Successful deliveries | Failures | Total | Failure rate | Actions |

Format distribution
Share and failure rate aggregated across all devices.
| Format | Deliveries | Share | Failure rate |
|---|---|---|---|
| AVIF | 33,802 | 65.58% | 0.47% |
| WebP | 9,663 | 18.75% | 2.18% |
| JPEG | 8,075 | 15.67% | 3.16% |
Fallback readiness
Rows above the threshold should trigger forced fallback scheduling.
- JPEG on Legacy Android is at 5.39% failure rate. Prepare fallback delivery.
- JPEG on Smart TV is at 3.42% failure rate. Prepare fallback delivery.
- WebP on Mobile is at 2.18% failure rate. Prepare fallback delivery.
- JPEG on Desktop is at 2.18% failure rate. Prepare fallback delivery.
Overview
Monitor delivery format share, device-level failure rates, and fallback thresholds entirely in the browser so distribution teams can react fast.
How to use
- Set the failure threshold that should trigger forced fallbacks.
- Add device and format delivery counts manually or load the sample dataset.
- Review flagged rows and export CSV snapshots for incident runbooks.
Use cases
- Decide when to fall back from AVIF/WebP to JPEG for specific device classes.
- Share rollout telemetry during incident reviews without exposing raw delivery logs.
- Align delivery format experiments with SLO guardrails and fallback plans.
Tips & knowledge
- Mirror device naming from observability dashboards for quick cross-checking.
- Keep exported CSVs for weekly trend reviews and regression detection.
- Pair with Performance Guardian alerts to connect format issues to Core Web Vitals.
