CAP Alert Statistics

Purpose

Displays counts and charts for CAP alerts on your site, including drafts: totals by severity, urgency, certainty, status, and hazard type, along with a monthly trend. Alerts can be filtered by date range and severity, and the filtered set can be exported as CSV.

To open it: Alerts → Statistics.

Screenshot

The page opens with the filter bar, summary cards, and CSV export button, followed by all six charts: alerts over time, by severity, by urgency, by certainty, by status, and top hazard types.

Below the Top Hazard Types chart, a table lists each hazard type with its count and share of the total.

Field Reference

Filter bar

Field	Type	Required	Description
From	Date	No	Restricts results to alerts sent on or after this date.
To	Date	No	Restricts results to alerts sent on or before this date.
Severity	Checkboxes (Extreme, Severe, Moderate, Minor)	No	Restricts results to the checked severities. With none checked, all severities are included.

Apply runs the filters. Reset clears them. Filters apply to the summary cards, charts, breakdown table, and CSV export together.

Summary cards

Card	Shows
Total Alerts	Count of alerts matching the current filters.
Extreme / Severe / Moderate / Minor	Count of alerts at that severity level. A card appears only if at least one matching alert has that severity.

Alerts with no recorded severity, such as incomplete drafts or alerts imported from an external CAP feed missing that field, count toward Total Alerts without a corresponding card. The four severity cards do not always sum to the total.

Charts

Chart	Shows
Alerts Over Time (Monthly)	Alert count per calendar month, as a line chart.
By Severity	Matching alerts grouped by severity level.
By Urgency	Matching alerts grouped by urgency (Immediate, Expected, Future, Past).
By Certainty	Matching alerts grouped by certainty (Observed, Likely, Possible, Unlikely).
By Status	Matching alerts grouped by status (Actual, Test, Exercise, Draft, System), as a donut chart.
Top Hazard Types	The 15 most common hazard/event types among matching alerts, as a horizontal bar chart.

Charts with no matching data are hidden.

Alerts by Hazard Type (table)

Lists the top 15 hazard types among the matching alerts, with each type’s count and its share of the total as a proportional bar. Percentages are computed against the true total alert count, not the sum of the listed types. With more than 15 hazard types in use, the remainder are omitted and the listed percentages will not sum to 100%.

Export

Download CSV exports every alert matching the current filters, not only the ones charted, as a CSV file with one row per alert and these columns: ID, Title, Sent, Status, Message Type, Scope, Sender, Severity, Urgency, Certainty, Event, and Area Description.
