Written by
Updated at December 17, 2024

Retrieves logs for the specified OpenSearch cluster.
For detailed description, see the Logs section in the developer's guide.

gRPC request

rpc ListLogs (ListClusterLogsRequest) returns (ListClusterLogsResponse)

ListClusterLogsRequest

{
  "cluster_id": "string",
  "column_filter": [
    "string"
  ],
  "from_time": "google.protobuf.Timestamp",
  "to_time": "google.protobuf.Timestamp",
  "page_size": "int64",
  "page_token": "string",
  "always_next_page_token": "bool",
  "filter": "string",
  "service_type": "ServiceType"
}

Field

Description

cluster_id

string

Required field. ID of the OpenSearch cluster to request logs for.

To get the OpenSearch cluster ID use a ClusterService.List request.

column_filter[]

string

Columns from log table to request.
If no columns are specified, entire log records are returned.

from_time

google.protobuf.Timestamp

Start timestamp for the logs request.

to_time

google.protobuf.Timestamp

End timestamp for the logs request.

page_size

int64

The maximum number of results per page to return.

If the number of available results is larger than page_size, the service returns a ListClusterLogsResponse.next_page_token
that can be used to get the next page of results in subsequent list requests.

page_token

string

Page token. To get the next page of results, set page_token to the
ListClusterLogsResponse.next_page_token returned by the previous list request.

always_next_page_token

bool

The service always returns a ListClusterLogsResponse.next_page_token, even if the current page is empty.

filter

string

A filter expression that filters resources listed in the response.

The expression must specify:

  1. A field name. Currently filtering can be applied to the [LogRecord.logs.message.hostname] field.

  2. A conditional operator. Can be either = or != for single values, IN or NOT IN for lists of values.

  3. A value. Must be 1-63 characters long and match the regular expression ^[a-z0-9.-]{1,61}$.

Examples of a filter:

  • message.hostname='node1.db.cloud.yandex.net';
  • message.error_severity IN ("ERROR", "FATAL", "PANIC") AND message.hostname = "node1.db.cloud.yandex.net".

service_type

enum ServiceType

Type of the service to request logs about.

  • SERVICE_TYPE_UNSPECIFIED: Type is not specified.
  • OPENSEARCH: OpenSearch logs.
  • DASHBOARDS: Dashboards logs.

ListClusterLogsResponse

{
  "logs": [
    {
      "timestamp": "google.protobuf.Timestamp",
      "message": "map<string, string>"
    }
  ],
  "next_page_token": "string"
}

Field

Description

logs[]

LogRecord

Requested log records.

next_page_token

string

This token allows you to get the next page of results for list requests.

If the number of results is larger than ListClusterLogsRequest.page_size, use the next_page_token as the value
for the ListClusterLogsRequest.page_token query parameter in the next list request.

Each subsequent list request has its own next_page_token to continue paging through the results.

This value is interchangeable with the StreamLogRecord.next_record_token from StreamLogs method.

LogRecord

Field

Description

timestamp

google.protobuf.Timestamp

Time when the log was recorded.

message

object (map<string, string>)

Contents of the log record.
