List log streams in a group.

GET
/v1/projects/{projectId}/observability/log-groups/{logGroupId}/streams
Code sample: Shell / cURL
curl --request GET \
  --url https://stratum.example.com/v1/projects/example/observability/log-groups/example/streams \
  --header 'Authorization: Bearer <token>'

Streams are auto-created by PutLogEvents on first event with a new stream name. The Stratum service tracks per-stream watermarks (first/last event timestamp, total bytes) for the list response; event content itself lives in VictoriaLogs.

displayName

operator-friendly stream label. Resolved server- side by the observability service: when the stream name matches a registered hypervisor node id (n-<slug>), the node’s name from /v1/compute/nodes is surfaced here. Substrate streams therefore show “stratum-01” instead of the raw n-id in selectors and log-tail widgets. Empty when no node-name resolver matched (customer streams, unknown node ids); the UI falls back to name.

storedBytes
required

Cumulative bytes shipped to VictoriaLogs under this stream.

integer format: int64
createdAt
required
string format: date-time
nextPageToken
string
isTruncated

True when the server had more rows than it returned. The response is a valid prefix of the result, not the whole of it.

Without this flag a client at the server’s row ceiling receives a full page and no nextPageToken, which means “this is the complete set” — so data it never saw would be indistinguishable from data that does not exist.

It does not imply a cursor exists. These queries do not all sort on a total order, so a resumable token cannot be minted for them yet. The remedy is to narrow the request (filter, or a shorter time range), not to page.

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.
