PowerQuery
// Rule: 17_daily_baseline_new_locations
|
|
// User signing in today from a country never seen in 14d baseline
|
|
//
|
|
// Source KQL: see ../kql/17_daily_baseline_new_locations.kql
|
|
//
|
|
// HOW TO RUN
|
|
// curl POST {sdl}/api/powerQuery with this body, OR paste in
|
|
// the SDL console. Set startTime = '2h' (or wider) so the API
|
|
// scans the freshly-ingested epochs that contain the events.
|
|
//
|
|
// Time anchor at export: NOW = 2026-05-31T20:10:05+00:00
|
|
// Recent-window cutoff: 2026-05-31T18:10:05+00:00
|
|
// (`ts_epoch_ms` below is that cutoff expressed in ms.
|
|
// Re-run harness/export_rules.py to refresh after regenerating
|
|
// sample_data/events.jsonl.)
|
|
//
|
|
// Fields referenced: Location, RECENT_MS, ResultType, SigninLogs, TodayCountries, UserPrincipalName
|
|
//
|
|
// EDITING NOTE
|
|
// Every line that starts with `|` is a pipeline stage. Each `|`
|
|
// is REQUIRED. If you delete one (e.g. while changing a literal
|
|
// on the same line as a stage), SDL re-parses the keyword that
|
|
// follows as a search term and rejects the query with errors
|
|
// like `'estimate_distinct' is a grouping function`.
