  • Getting a cluster log
  • Getting a cluster log stream

Yandex StoreDoc allows you to get a cluster log snippet for the selected period and view logs in real time.

Note

Cluster logs are kept for 30 days.

Getting a cluster logGetting a cluster log

Management console
CLI
REST API
gRPC API
  1. Go to the page of the folder where the cluster resides.
  2. Go to Yandex StoreDoc.
  3. Click the name of your cluster and select the Logs tab.
  4. Specify a time period for the log entries you want to view: enter it manually or select in the calendar using the date input field.
  5. Specify the hosts and logging level in the row with the date input field, if required.

You will see a list of log entries for the time period you specified. To view detailed information about an event, click the relevant entry in the list.

If there are too many entries and not all of them are displayed, click Load more at the end of the list.

If you do not have the Yandex Cloud CLI installed yet, install and initialize it.

By default, the CLI uses the folder specified when creating the profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also set a different folder for any specific command using the --folder-name or --folder-id parameter.

  1. View the description of the CLI command for viewing cluster logs:

    yc managed-mongodb cluster list-logs --help
    
  2. Run the following command to get cluster logs (our example only shows some of the available parameters):

    yc managed-mongodb cluster list-logs <cluster_name_or_ID> \
       --limit <entry_number_limit> \
       --service-type <service_type> \
       --columns <list_of_data_columns> \
       --filter <entry_filtration_settings> \
       --since <time_range_start> \
       --until <time_range_end>
    

    Where:

    • --limit: limits on the number of entries to output.

    • --service-type: Type of the service for which you want to output entries (mongod, mongos, mongocfg, or audit).

    • --columns: List of output data columns:

      • component: Type of component to log. e.g., CONTROL.
      • context: Name of the executable module, e.g., signalProcessingThread.
      • hostname: Host name.
      • message: Message output by the component.
      • severity: Logging level, e.g., I or W (Info and Warning, respectively).

      Note

      The list of data columns depends on the selected --service-type.

    • --filter: record filter settings, for example, message.hostname='node1.mdb.yandexcloud.net'.

    • --since: Left boundary of a time range in RFC-3339, HH:MM:SS format or a time interval relative to the current time. Examples: 2006-01-02T15:04:05Z, 15:04:05, 2h, 3h30m ago.

    • --until: right boundary of a time range, the format is similar to that of --since.

You can get the cluster name and ID with the list of clusters in the folder.

  1. Get an IAM token for API authentication and put it into an environment variable:

    export IAM_TOKEN="<IAM_token>"
    
  2. Call the Cluster.ListLogs method, e.g., via the following cURL request:

    curl \
        --request GET \
        --header "Authorization: Bearer $IAM_TOKEN" \
        --url 'https://mdb.api.cloud.yandex.net/managed-mongodb/v1/clusters/<cluster_ID>:logs' \
        --url-query serviceType=<service_type> \
        --url-query columnFilter=<column_list> \
        --url-query fromTime=<time_range_start> \
        --url-query toTime=<time_range_end>
    

    Where:

    • serviceType: Type of the service for which you want to get logs:

      • MONGOD: Yandex StoreDoc operations log.
      • AUDIT: Audit log.
    • columnFilter: List of output data columns:

      • hostname: Host name.
      • component: Type of component to log, Example: HTTP-Session.
      • message: Message output by the component.
      • query_id: Request ID.
      • severity: Logging level, e.g., Debug.
      • thread: ID of the thread involved in query handling.

      You can specify only one column in the columnFilter parameter. If you want to filter logs by more than one column, provide a list of the columns in several parameters.

      • fromTime: Left boundary of a time range in RFC-3339 format, Example: 2006-01-02T15:04:05Z.
      • toTime: End of the time range in the same format as fromTime.

    You can get the cluster ID with the list of clusters in the folder.

  3. View the server response to make sure your request was successful.

  1. Get an IAM token for API authentication and put it into an environment variable:

    export IAM_TOKEN="<IAM_token>"
    
  2. Clone the cloudapi repository:

    cd ~/ && git clone --depth=1 https://github.com/yandex-cloud/cloudapi
    

    Below, we assume that the repository contents reside in the ~/cloudapi/ directory.

  3. Call the ClusterService.ListLogs method, e.g., via the following gRPCurl request:

    grpcurl \
      -format json \
      -import-path ~/cloudapi/ \
      -import-path ~/cloudapi/third_party/googleapis/ \
      -proto ~/cloudapi/yandex/cloud/mdb/mongodb/v1/cluster_service.proto \
      -rpc-header "Authorization: Bearer $IAM_TOKEN" \
      -d '{
            "cluster_id": "<cluster_ID>",
            "service_type": "<service_type>",
            "column_filter": [
              "<column_1>", "<column_2>", ..., "<column_N>"
            ],
            "from_time": "<time_range_start>",
            "to_time": "<time_range_end>"
          }' \
      mdb.api.cloud.yandex.net:443 \
      yandex.cloud.mdb.mongodb.v1.ClusterService.ListLogs
    

    Where:

    • service_type: Type of the service for which you want to get logs:

      • MONGOD: Yandex StoreDoc operations log.
      • AUDIT: Audit log.
    • column_filter: List of output data columns:

      • component: Type of component to log, Example: HTTP-Session.
      • message: Message output by the component.
      • query_id: Request ID.
      • severity: Logging level, e.g., Debug.
      • thread: ID of the thread involved in query handling.

      You can specify more than one column in the column_filter parameter if you want to filter logs by multiple columns.

      • from_time: Left boundary of a time range in RFC-3339 format, Example: 2006-01-02T15:04:05Z.
      • to_time: End of the time range in the same format as from_time.

    You can get the cluster ID with the list of clusters in the folder.

  4. Check the server response to make sure your request was successful.

Getting a cluster log streamGetting a cluster log stream

This method allows you to get cluster logs in real time.

CLI
REST API
gRPC API

If you do not have the Yandex Cloud CLI installed yet, install and initialize it.

By default, the CLI uses the folder specified when creating the profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also set a different folder for any specific command using the --folder-name or --folder-id parameter.

To view cluster logs in real time, run this command:

yc managed-mongodb cluster list-logs <cluster_name_or_ID> --follow

You can get the cluster name and ID with the list of clusters in the folder.

  1. Get an IAM token for API authentication and put it into an environment variable:

    export IAM_TOKEN="<IAM_token>"
    
  2. Call the Cluster.StreamLogs method, e.g., via the following cURL request:

    curl \
        --request GET \
        --header "Authorization: Bearer $IAM_TOKEN" \
        --url 'https://mdb.api.cloud.yandex.net/managed-mongodb/v1/clusters/<cluster_ID>:stream_logs' \
        --url-query serviceType=<service_type> \
        --url-query columnFilter=<column_list> \
        --url-query fromTime=<time_range_start> \
        --url-query toTime=<time_range_end> \
        --url-query filter=<log_filter>
    

    Where:

    • serviceType: Type of the service for which you want to get logs:

      • MONGOD: Yandex StoreDoc operations log.
      • AUDIT: Audit log.
    • columnFilter: List of output data columns:

      • hostname: Host name.
      • component: Type of component to log, Example: HTTP-Session.

      • query_id: Request ID.
      • severity: Logging level, e.g., Debug.
      • thread: ID of the thread involved in query handling.

      You can specify only one column in the columnFilter parameter. If you want to filter logs by more than one column, provide a list of the columns in several parameters.

      • fromTime: Left boundary of a time range in RFC-3339 format, Example: 2006-01-02T15:04:05Z.
      • toTime: End of the time range in the same format as fromTime.
    • filter: Log filter. You can filter logs so that the stream contains only the logs you need.

      For more information about filters and their syntax, see the API reference.

      Tip

      A filter can contain quotation marks and other characters. Escape them if you need to.

      Supported filters:

      • message.hostname: Filtering by host name.
