emfEnabled

. When true, the PutLogEvents path scans each event message as JSON and extracts AWS Embedded Metric Format (_aws.CloudWatchMetrics) metrics, emitting them through the standard OTel SDK path. The log line still ships to VictoriaLogs unchanged. Defaults to false to avoid cardinality surprises.

origin

Provenance marker. Empty for customer-created groups; one of platform.system / platform.audit-shadow for the two auto-created-per-project groups, platform.pack for substrate groups, platform.image-builder for image build output, and platform.guest-logs for the instances group the instance agent ships guest logs to (one stream per instance, each line stamped instance_id by the control plane; the API cannot write to it).

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.

object

code

required

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

string

statement

required

Index of the statement at fault; -1 for the document as a whole.

integer

>= -1

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.

object

field

required

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

string

message

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.
