A group is a rule (or an SLO tier) with at least one pending, firing, noData or silenced instance the filters keep; it carries its first 10 instances in the instance order (as GET alerts) and total. Groups are ordered by worstState (firing, noData, pending, silenced), then the latest latestChangeAt first, then owner ID. commonLabels are the labels every instance of the group shares (all of them, not only those returned); each instance's distinctLabels are the rest. The top-level counts are the project's instances by display state under every filter except state, and ruleErrors the rules in rule error. limit is 1-50 groups (default 20). A content read: unrecorded. 404 while alerting isn't offered (the console hides Alerting then). ## Authentication Requires one of the following: - `apiKey`, http, header `Authorization` - `oauth`, http, header `Authorization` - `sessionCookie`, apiKey, in cookie ## Path parameters - `ListAlertGroups.path.orgId` (string, required) - format `uuid` - `ListAlertGroups.path.projectId` (string, required) - format `uuid` ## Query parameters - `ListAlertGroups.query.limit` (integer, optional) — The page size.
