`GET /v1/organizations/{orgId}/projects/{projectId}/obs/alerts`

Pending, firing and noData instances, and those resolved in the last 15 minutes, with the silences that mute them, in the instance order: firing, noData, pending, silenced, resolved, then the newest activeAt first, then fingerprint. silenced is a display state: a pending, firing or noData instance that an active silence matches (state keeps its underlying state). total counts the instances the filters keep. limit is 1-100 (default 50). A content read: unrecorded. 404 while alerting isn't offered (the console hides Alerting then).

  - format `uuid`
- `ListAlerts.path.projectId` (string, required)

    - format `date-time`
  - `ListAlerts.response.200.alerts.annotations` (map<string>, required) — Rendered.
  - `ListAlerts.response.200.alerts.distinctLabels` (map<string>, required) — labels without those every instance of its group (its rule, or SLO tier, under the list's filters) shares.
  - `ListAlerts.response.200.alerts.fingerprint` (string, required) — 16 hex digits: the hash of the instance's labels.

    - format `uuid`
  - `ListAlerts.response.200.alerts.state` (string, required) — pending, firing, noData or resolved (kept 15 minutes): the underlying state; a silenced one has silencedBy.
  - `ListAlerts.response.200.alerts.value` (number | null, required)

- `ListAlerts.response.200.total` (integer, required) — The instances the filters keep; a lower bound when truncated.
- `ListAlerts.response.200.truncated` (boolean, required) — True when the filters keep more instances than one request reads (20,000, the most severe state and the newest activeAt first): total is then a lower bound and paging ends early. The filters that narrow the read are owner, severity, q, label name=value and name!=value, and state other than silenced; label regular expressions and state=silenced are applied to the instances read.
