Search traces by service / operation / duration / time.

POST
/v1/projects/{projectId}/observability/traces/actions/search
Code sample: Shell / cURL
curl --request POST \
  --url https://stratum.example.com/v1/projects/example/observability/traces/actions/search \
  --header 'Authorization: Bearer <token>' \
  --header 'Content-Type: application/json' \
  --data '{ "service": "example", "operation": "example", "operations": [ "example" ], "minDuration": 1, "maxDuration": 1, "start": "2026-04-15T12:00:00Z", "end": "2026-04-15T12:00:00Z", "limit": 1, "instanceId": "example" }'

Finds the project’s own spans and the control plane’s spans of requests made against the project (span attribute stratum.project.id). instanceId narrows to the requests that acted on one instance (span attribute stratum.instance.id, ).

service
string
operation

Exact span name.

string
operations

Operations from the operation catalog, ORed: a trace matches when one of its spans matches any of them. <METHOD> <route> matches http.route + http.method, a bare /route matches http.route for any method, anything else matches the span name. Spans recorded before route-template naming match by their raw path. ANDed with operation when both are set.

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

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.
