有什么方法可以从java类访问Windows事件日志。有没有人为此编写过任何API,并且有没有办法从远程机器访问数据?如何从Java访问Windows事件查看器日志数据
的情况是:
我在远程机器上运行的过程,从控制Java进程。 这个远程进程记录东西到事件日志,我想在控制过程中看到。
在此先感谢。

在Java方面,您需要一个允许您进行本地调用的库。 Sun提供JNI,但听起来有点痛苦。还认为:
在Windows端,功能你就是OpenEventLog后。这应该允许您访问远程事件日志。另见Querying for Event Information。
如果没有健全的权利,我也发现了这个直接解析日志文件(没有办法,我建议,但有趣的仍然):
如果您想要从远程计算机访问真正的事件日志,您必须找到一个实现EventLog Remoting Protocol Specification的库。不幸的是,我还没有在Java中找到任何这样的库。然而,JCIFS和JARAPAC项目已经奠定了实施该协议的大部分基础。协议本身(如果我没有弄错的话)运行在DCE/RPC协议之上(由JARAPAC实现),它本身在SMB协议之上运行(由JCIFS实现)。
我已经使用JCIFS和JARAPAC来实现一些EventLog的表亲协议,例如远程注册表访问。我可能是盲目的,但是关于JARAPAC文档似乎有点缺乏。如果你有兴趣实施这个,我可以与你分享我在空闲时间学到的知识!
后来!
http://www.j-interop.org/是实现DCOM协议规范,而无需使用任何本地代码一个开放源代码的Java库。 (即,您可以使用它从非Windows客户端上运行的Java代码访问远程Windows主机上的DCOM对象)。
Microsoft通过Windows Management Instrumentation(WMI)公开了大量的系统信息。 WMI可以通过DCOM远程访问,并且微软网站上还有相关的主题文档。碰巧,您可以通过这个可远程访问的界面访问Windows Event Logs。
通过使用j-interop,您可以远程创建WbemScripting.SWbemLocator WMI对象的实例,然后连接到远程Windows主机上的Windows Management Instrumentation(WMI)服务。从那里你可以提交一个query,每当写入新的事件日志条目时都会通知你。
请注意,这确实需要您在远程Windows主机上正确启用和配置DCOM,并且已在任何防火墙中设置了适当的例外。有关这方面的详细信息可以在线搜索,也可以从上面的j-interop网站中查阅。
以下示例使用其NT域,主机名,用户名和密码连接到远程主机,并且位于一个循环中,并在每个事件日志条目按照由Windows记录的方式进行转储时进行转储。用户必须已被授予适当的远程DCOM访问权限,但不必是管理员。

有100万(及一个)选择这里;)
你可以看看SIGAR
记住,虽然发牌....
或者你可以快速和肮脏,只是periodi卡利执行(并捕获输出) d:>的Cscript.exe C:\窗口\ system32 \ eventquery.vbs/v的
然后使用事件过滤PARAMS细化结果等... http://technet.microsoft.com/en-us/library/cc772995(WS.10).aspx
阅读this article。
JNA 3.2.8具有从Windows事件日志读取和写入的两种方法。
您可以在log4jna中看到写入示例。
这里读的例子:
EventLogIterator iter = new EventLogIterator("Application");
while(iter.hasNext()) {
EventLogRecord record = iter.next();
System.out.println(record.getRecordNumber()
+ ": Event ID: " + record.getEventId()
+ ", Event Type: " + record.getType()
+ ", Event Source: " + record.getSource());
}
