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 Yandex StoreDoc logs:

1. See the description of the CLI command for viewing logs:

   yc managed-mongodb cluster list-logs --help
   

2. To retrieve all cluster logs, run this command:

   yc managed-mongodb cluster list-logs --id <cluster_ID>
   

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

1. Get an IAM token for API authentication and place it in 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: Target service type for log retrieval:

     • MONGOD: Yandex StoreDoc operations log.
     • AUDIT: Audit log.

   • columnFilter: List of output 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 from the list of clusters in your folder.

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

1. Get an IAM token for API authentication and place it in 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: Target service type for log retrieval:

     • MONGOD: Yandex StoreDoc operations log.
     • AUDIT: Audit log.

   • column_filter: List of output 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 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 from the list of clusters in your folder.

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