批量ping操作

1 批量ping操作，所需jar包

        <dependency> <groupId>net.sf.json-lib</groupId> <artifactId>json-lib</artifactId> <version>2.4</version> <classifier>jdk13</classifier> </dependency> <dependency> <groupId>net.java.dev.jna</groupId> <artifactId>jna</artifactId> <version>4.0.0</version> </dependency> <dependency> <groupId>net.java.dev.jna</groupId> <artifactId>jna-platform</artifactId> <version>4.0.0</version> </dependency>

2 工具包下载

点击下载工具包 dpso，解压后，拷贝到linux下，如：/opt/log/目录下

3 Java测试代码

package com.wutongyu.test; import com.sun.jna.Library; import com.sun.jna.Native; import com.sun.jna.Pointer; import java.text.SimpleDateFormat; import java.util.Date; /**  * Created by wutongyu on 2018/2/24.  */ public class TestPing { public interface LgetLib extends Library { LgetLib INSTANCE = (LgetLib) Native.loadLibrary("/opt/log/dpso/host_scan/lib/libdba_capi.so", LgetLib.class); Pointer callFunc(String action, String params ); void freeFunc( Pointer paramPointer );   public static String call(String action, String params) { Pointer point=LgetLib.INSTANCE.callFunc(action, params); String ret = point.getString(0L); LgetLib.INSTANCE.freeFunc(point); return ret;   public static void main(String[] args) { SimpleDateFormat bartDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); while (true){ Date date=new Date(); String dateStr = bartDateFormat.format(date); String callstr = TestPing.call("host_scan", "{\"count\":5, \"timeout\":10000, \"interval\":100, \"hosts\":[\"10.238.129.11\",\"10.238.129.41\",\"10.238.129.18\",\"10.238.129.47\",]}"); System.out.println(dateStr++callstr); try { Thread.sleep(120*1000L); catch (InterruptedException e) { e.printStackTrace();    } 

4 返回值及解析

返回如下Json串： {     "errcode":"ERRCODE",     "errmsg":"ERRMSG",     "data":     [         {             "host":"10.238.129.11",             "min_reply_msec":"0",             "max_reply_msec":"0",             "avg_reply_msec":"0",             "total_count":"5",             "lost_count":"5",             "lost_ratio":"1.0"         },         ...     ] } 参数说明：     host: ipv4或者ipv6地址,     min_reply_msec: 最小响应时间，单位：毫秒,     max_reply_msec: 最大响应时间，单位：毫秒,     avg_reply_msec: 平均响应时间，单位：毫秒,     total_count: 总包数,     lost_count: 丢包数,     lost_ratio: 丢包率，以实数表示，例如：0.5表示丢包率50%。 一般的，当丢包率为1.0时，认为ping不通
