StreamLogs

Same as ListLogs but using server-side streaming. Also allows for 'tail -f' semantics.

import { cloudApi, serviceClients, Session } from "@yandex-cloud/nodejs-sdk";

const StreamClusterLogsRequest =
cloudApi.mdb.clickhouse_cluster_service.StreamClusterLogsRequest;
const StreamClusterLogsRequest_ServiceType =
cloudApi.mdb.clickhouse_cluster_service.StreamClusterLogsRequest_ServiceType;

(async () => {
const authToken = process.env["YC_OAUTH_TOKEN"];
const session = new Session({ oauthToken: authToken });
const client = session.client(serviceClients.ClusterServiceClient);

const result = await client.streamLogs(
StreamClusterLogsRequest.fromPartial({
clusterId: "clusterId",
// columnFilter: ["columnFilter"],
serviceType: StreamClusterLogsRequest_ServiceType.CLICKHOUSE,
// fromTime: {
// seconds: 0,
// nanos: 0
// },
// toTime: {
// seconds: 0,
// nanos: 0
// },
// recordToken: "recordToken",
// filter: "filter"
})
);
console.log(result);
})();

StreamClusterLogsRequest​

ServiceType​

  • SERVICE_TYPE_UNSPECIFIED

    Type is not specified.

  • OPENSEARCH

    OpenSearch logs.

  • DASHBOARDS

    Dashboards logs.

clusterId : string​

ID of the OpenSearch cluster.

columnFilter : string​

Columns from log table to get in the response. If no columns are specified, entire log records are returned.

fromTime : google.protobuf.Timestamp​

Start timestamp for the logs request.

toTime : google.protobuf.Timestamp​

End timestamp for the logs request.

If this field is not set, all existing logs are sent as well as the new ones as they appear.

In essence it has tail -f semantics.

recordToken : string​

Record token. Set record_token to the next_record_token returned by the previous StreamLogs request to start streaming from the next log record.

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".
serviceType : ServiceType​

Type of the service to request logs about.

StreamLogRecord​

record : LogRecord​

One of the requested log records.

nextRecordToken : string​

This token allows you to continue streaming logs starting from the exact same record.

To do that, specify value of next_record_token as the value for StreamLogs.record_token parameter in the next StreamLogs request.

This value is interchangeable with ListLogs.next_page_token from ListLogs method.

LogRecord​

timestamp : google.protobuf.Timestamp​

Time when the log was recorded.

message : string​

Contents of the log record.
