Feature Request

Is your feature request related to a problem? Please describe.

There is no centralized view of platform-level statistics on the monitoring dashboard. Admins and operators have no quick way to see overall system health and activity — such as how many donors are registered, how many searches ran today, or current request volume — without querying DynamoDB directly.

Describe the solution you'd like

Add a statistics section to the monitoring dashboard that displays real-time and aggregated platform metrics across donors, searches, and blood requests.

Donor Stats

• Total registered donors
• Active donors (donated in last 90 days)
• New donors this week / this month
• Donors by blood group (A+, A-, B+, B-, O+, O-, AB+, AB-)
• Donors by city / region
• Donors currently available

Search & Matching Stats

• Donor searches today / this week
• Average donors found per search
• Donors notified today
• Donors found by blood group
• Average time to first donor match
• Average search radius to find a match (km)

Blood Request Stats

• Active blood requests right now
• Requests completed today
• Requests by urgency (urgent vs regular)
• Requests by blood group
• Donor acceptance rate (% of notified donors who accepted)
• Average donor response time

Describe alternatives you've considered

• Exporting DynamoDB data to a spreadsheet for manual review — not scalable or real-time
• Using AWS CloudWatch metrics — covers infra-level metrics only, not business-level data
