Silence the alarm's notifications without stopping evaluation.

POST

/v1/projects/{projectId}/observability/alarms/{alarmId}/actions/disable

Code sample: Shell / cURL

curl --request POST \
  --url https://stratum.example.com/v1/projects/example/observability/alarms/example/actions/disable \

  --header 'Content-Type: application/json' \
  --data '{ "until": "2026-04-15T12:00:00Z" }'

• A Stratum cluster endpoint.

. Optional until ISO-8601 timestamp schedules an auto-flip-back to enabled. vmalert keeps evaluating + the history table records transitions; only outbound notifications are suppressed.

The updated alarm.

Media typeapplication/json

An alarm is either expression-based (raw PromQL pasted by the operator — expression set) or metric-based (CloudWatch shape — metricNamespace+metricName+statistic+comparisonOperator+ threshold set). The two forms are mutually exclusive at the DB level. Both forms require periodSeconds+evaluationPeriods+ datapointsToAlarm for the vmalert hold duration.

object

ownedBy

Set on a platform-owned row; absent on a tenant’s own.

object

kind

required

string

Allowed values: auto-scaling-group platform

id

required

The owner: the Auto Scaling group id, or for platform the component (front-door, pack:platform-health, default-network, operator-recipe).

string

expression

Raw PromQL expression. Mutually exclusive with the metric tuple + compositeExpression.

string

compositeExpression

. Boolean composition of child alarm states via the small grammar ALARM(name) AND ALARM(other) (also OK, INSUFFICIENT_DATA, NOT, parens). Mutually exclusive with expression + metric tuple. Children must live in the same project.

alarmActions

Notification-channel IDs to fire when this alarm transitions to ALARM. Every listed channel is notified; the order of the list does not matter.

Array<string>

enabled

required

boolean

actionsEnabled

. When false, vmalert keeps evaluating + the history table records transitions, but outbound notifications are suppressed. Distinct from enabled which stops evaluation entirely.

boolean

default: true

actionsEnabledUntil

. Set by the disable-actions endpoint’s until parameter. The silencer worker auto-flips actionsEnabled back to true at this time.

string format: date-time

nullable

treatMissingData

. CloudWatch TreatMissingData policy.

origin

. Provenance marker. platform.builtin is stamped by the Platform Health pack reconciler (once it owns alarms); every customer-created alarm is customer. Mirrors Dashboard.origin so the UI can render the substrate/customer split with the same model.

issues

The findings of a rejected IAM policy document (custom and resource policies).

Array<object>

One finding of a rejected IAM policy document. A rejection lists every finding, so the author fixes the document in one round trip.

The finding, e.g. INVALID_DOCUMENT, UNKNOWN_ACTION, ACTION_NOT_APPLICABLE.

detail

required

string

action

The offending action, where one is at fault (ACTION_NOT_APPLICABLE).

string

errors

Field errors, for codes that carry them: each problem at its field (see FieldError). Documented on the responses that set it, e.g. approveNodeJoin’s INVALID_INPUT and JOIN_APPROVAL_REFUSED. Absent otherwise.

Array<object>

One field’s problem, the stage-2 installer API’s shape. field is the field’s path, message what is wrong with it.

The field’s path, e.g. links[0].interface, disks[1].confirm, mgmt.address or role; empty for the whole request.

string

required

string

details

Structured facts about the refusal, for codes that carry them. The shape is fixed per code and documented on the response that answers it, e.g. IMAGE_POOL_MISMATCH (see ImagePoolMismatchDetails) and IMAGE_IN_USE. Absent for codes that carry none.
