Elasticsearch:Quick Start

Calling methods

Alibaba Cloud CLI example

1. Obtain the instance ID.

   You can obtain the instance ID in one of the following two ways:

   • In the Kibana console, run the GET / command. For more information, see Log on to the Kibana console.

   • On your local machine, call the ListInstance operation.

     aliyun elasticsearch ListInstance --zoneId cn-hangzhou

2. Call the ListSearchLog operation to retrieve system logs for the instance.

   aliyun elasticsearch ListSearchLog --type INSTANCELOG --query level:warn --beginTime 1593332477000 --endTime 1593418877000 --page 1 --size 20 --InstanceId es-cn-n6w1o1x0w00******   

OpenAPI Explorer example

1. Call the ListInstance operation to obtain the instance ID.

2. Call the ListSearchLog operation to query system logs for the instance.

   If the query is successful, OpenAPI Explorer displays the log information.

Java SDK example

1. Create a Maven project.

2. Configure the POM dependencies.

   <dependency>
       <groupId>com.aliyun</groupId>
       <artifactId>elasticsearch20170613</artifactId>
       <version>4.0.0</version>
   </dependency>
   <dependency>
       <groupId>com.aliyun</groupId>
       <artifactId>aliyun-java-sdk-core</artifactId>
       <version>4.4.6</version>
   </dependency>

   Important

   SDK packages are updated frequently. We recommend downloading the latest version from Alibaba Cloud SDKs.

3. Create a Java program and call the ListSearchLog operation to query system logs for the instance.

   import com.aliyuncs.CommonRequest;
   import com.aliyuncs.CommonResponse;
   import com.aliyuncs.DefaultAcsClient;
   import com.aliyuncs.IAcsClient;
   import com.aliyuncs.exceptions.ClientException;
   import com.aliyuncs.exceptions.ServerException;
   import com.aliyuncs.http.FormatType;
   import com.aliyuncs.http.MethodType;
   import com.aliyuncs.profile.DefaultProfile;
   public class ListSearchLog {
       public static void main(String[] args) {
           DefaultProfile profile = DefaultProfile.getProfile("<RegionId>", "<accessKeyId>", "<accessSecret>");
           IAcsClient client = new DefaultAcsClient(profile);
   
           CommonRequest request = new CommonRequest();
           //request.setProtocol(ProtocolType.HTTPS);
           request.setMethod(MethodType.GET);
           request.setDomain("elasticsearch.<RegionId>.aliyuncs.com");
           request.setVersion("2017-06-13");
           request.setUriPattern("/openapi/instances/<instanceid>/search-log");
           request.putQueryParameter("type", "INSTANCELOG");
           request.putQueryParameter("query", "level:warn");
           request.putQueryParameter("beginTime", "1593332477000");
           request.putQueryParameter("endTime", "1593418877000");
           request.putQueryParameter("page", "1");
           request.putQueryParameter("size", "20");
           request.putHeadParameter("Content-Type", "application/json");
           String requestBody = "{}";
           request.setHttpContent(requestBody.getBytes(), "utf-8", FormatType.JSON);
           try {
               CommonResponse response = client.getCommonResponse(request);
               System.out.println(response.getData());
           } catch (ServerException e) {
               e.printStackTrace();
           } catch (ClientException e) {
               e.printStackTrace();
           }
       }
   }
