Add an Alibaba Cloud Elastic Search data source-DataV(DataV)-阿里云帮助中心

This topic describes how to add and use an Alibaba Cloud Elasticsearch data source in DataV. You can use Elasticsearch with DataV to display data analytics and search results on a large screen.

Prerequisites

You have an Elasticsearch data source ready to be added.

Add an Alibaba Cloud Elastic Search data source

Log on to the DataV console.
On the My Data tab, select Data Source Management and click Add Data.
From the Type list, select Elasticsearch.

Enter the information for the Elasticsearch data source.

Important DataV requires access to your Alibaba Cloud Elasticsearch service to use it as a data source. This access is granted by a service-linked role.

In the Add Data dialog box, click Get Instance List. In the dialog box that appears, view the information about the service-linked role.

Role Name: AliyunServiceRoleForDataVDataSourceES
System Policy: AliyunServiceRolePolicyForDataVDataSourceES

Permission Description: Allows the DataV service to use this role to access your Elasticsearch, RDS, and ADS product services.

Policy details:

{
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "elasticsearch:ListInstance",
                "elasticsearch:DescribeInstance",

                "adb:DescribeDBClusterAttribute",
                "gpdb:DescribeDBInstanceNetInfo"
            ],
            "Resource": "*"
        },
        {
            "Action": "ram:DeleteServiceLinkedRole",
