本教程详细介绍如何使用Alibaba Cloud SDK for Java查询云监控插件信息。
前提条件
在使用本教程前，请确保已完成以下操作：
- 使用Alibaba Cloud SDK for Java，您需要一个阿里云账号和访问密钥（AccessKey）。 请在阿里云控制台中的AccessKey管理页面上创建和查看您的AccessKey。
- 确保您已经安装了Alibaba Cloud SDK for Java，准确的SDK版本号，请参见阿里云开发工具包（SDK）。

代码示例
本文操作示例主要以代码形式体现，具体代码如下：
import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.IAcsClient;
import com.aliyuncs.cms.model.v20190101.*;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.profile.DefaultProfile;
import com.google.gson.Gson;
import java.util.List;
/**
* 查询云监控插件信息。
*/
public class DescribeMonitoringAgentInfoDemo {
/**
* 查询所有的已安装和未安装云监控插件的主机列表。
*/
private DescribeMonitoringAgentHostsResponse describeMonitoringAgentHosts(DescribeMonitoringAgentHostsRequest request, IAcsClient client) {
try {
// 调用SDK发送请求
return client.getAcsResponse(request);
} catch (ClientException e) {
e.printStackTrace();
// 发生调用错误，抛出运行时异常
throw new RuntimeException();
}
}
/**
* 查询云监控插件运行状态。
*/
private DescribeMonitoringAgentStatusesResponse describeMonitoringAgentStatuses(DescribeMonitoringAgentStatusesRequest request, IAcsClient client) {
try {
// 调用SDK发送请求
return client.getAcsResponse(request);
} catch (ClientException e) {
e.printStackTrace();
// 发生调用错误，抛出运行时异常
throw new RuntimeException();
}
}
/**
* 查询云监控插件的配置信息。
*/
private DescribeMonitoringAgentConfigResponse describeMonitoringAgentConfig(DescribeMonitoringAgentConfigRequest request, IAcsClient client){
try {
// 调用SDK发送请求
return client.getAcsResponse(request);
} catch (ClientException e) {
e.printStackTrace();
// 发生调用错误，抛出运行时异常
throw new RuntimeException();
}
}
private static void log_print(String methodName, String result) {
System.out.println("-------------------------------" + methodName + "-------------------------------");
System.out.println(result);
}
public static void main(String[] args) {
// 设置鉴权参数，初始化客户端
DefaultProfile profile = DefaultProfile.getProfile(
"cn-zhangjiakou",// 地域ID
"your-access-key-id",// 您的AccessKey ID
"your-access-key-secret");// 您的AccessKey Secret
IAcsClient client = new DefaultAcsClient(profile);
Gson gson = new Gson();
DescribeMonitoringAgentInfoDemo describeMonitoringAgentInfoDemo = new DescribeMonitoringAgentInfoDemo();
// 获取安装云监控插件的主机列表
DescribeMonitoringAgentHostsRequest describeMonitoringAgentHostsRequest = new DescribeMonitoringAgentHostsRequest();
DescribeMonitoringAgentHostsResponse describeMonitoringAgentHostsResponse = describeMonitoringAgentInfoDemo.describeMonitoringAgentHosts(describeMonitoringAgentHostsRequest, client);
log_print("describeMonitoringAgentHosts",gson.toJson(describeMonitoringAgentHostsResponse));
// 将返回的主机列表拼接成一个逗号分隔的字符串
List<DescribeMonitoringAgentHostsResponse.Host> hosts = describeMonitoringAgentHostsResponse.getHosts();
StringBuilder instanceIdsb =new StringBuilder();
for (DescribeMonitoringAgentHostsResponse.Host host : hosts) {
String instanceId = host.getInstanceId();
instanceIdsb.append(instanceId);
instanceIdsb.append(",");
}
String instanceIdsStr = instanceIdsb.toString();
// 去掉最后一个逗号
String instanceIds = instanceIdsStr.substring(0, instanceIdsStr.length() - 1);
// 查询云监控插件运行状态
DescribeMonitoringAgentStatusesRequest describeMonitoringAgentStatusesRequest = new DescribeMonitoringAgentStatusesRequest();
describeMonitoringAgentStatusesRequest.setInstanceIds(instanceIds);
DescribeMonitoringAgentStatusesResponse describeMonitoringAgentStatusesResponse = describeMonitoringAgentInfoDemo.describeMonitoringAgentStatuses(describeMonitoringAgentStatusesRequest, client);
log_print("describeMonitoringAgentStatuses",gson.toJson(describeMonitoringAgentStatusesResponse));
// 查询云监控插件的配置信息
DescribeMonitoringAgentConfigRequest describeMonitoringAgentConfigRequest = new DescribeMonitoringAgentConfigRequest();
DescribeMonitoringAgentConfigResponse describeMonitoringAgentConfigResponse = describeMonitoringAgentInfoDemo.describeMonitoringAgentConfig(describeMonitoringAgentConfigRequest, client);
log_print("describeMonitoringAgentConfig",gson.toJson(describeMonitoringAgentConfigResponse));
}
}运行结果
正确运行结果类似如下：
