简介

中文 | English

这是阿里云应用诊断分析平台(ATP)的数据源生成工具，它可以帮助您生成Java堆转储(Heap dump)文件、Java线程栈日志等，它支持仅包含JRE的环境，以及AlpineJDK等特殊环境，可以运行在Windows/MacOS/Linux，目标虚拟机支持JDK6到JDK20。

作为命令行工具使用

您可以编译、构建出jar包，并通过Java命令行直接执行它

$ mvn package
$ java -Xbootclasspath/a:atp-client-api/src/main/resources/atp-client-tool.jar -jar atp-client-api/src/main/resources/atp-client-tool.jar

参数如下

Usage:
Main <pid> <subcommand> <options>

作为Java SDK使用

您可以添加如下Maven依赖并通过SDK方式调用：

<dependency>
  <groupId>com.aliyun.atp</groupId>
  <artifactId>atp-client-api</artifactId>
  <version>1.0.4</version>
</dependency>

import com.aliyun.atp.tool.ATPClient;
import com.aliyun.atp.tool.ClientException;

public class SDKExample {
    public static void main(String[] args) {
        try {
            ATPClient.execute(null);
            ATPClient.execute(new String[]{"<pid>", "thread"});
            ATPClient.execute(new String[]{"<pid>", "full_jcmd"});
            ATPClient.execute(new String[]{"<pid>", "heap", "-file=/tmp/heapdump.hprof","-object=all"});
            ATPClient.execute(new String[]{"<pid>", "heap", "-file=/tmp/heapdump.hprof","-object=live"});
        } catch (ClientException e) {
            e.printStackTrace();
        }
    }
}
