Jython jmxmp协议支持

Question

我正在为zabbix开发监控脚本和模板的集合.它被称为ZTC,所有脚本都在python上.

现在我想添加一些java监控的支持.我没有找到从CPython中做到这一点的方法 - 仅限于java或jython.由于所有项目都在python上,我决定在jython上编写一个简单的脚本,它将从我的cpython类中调用.

以下是我的代码的样子:

#!/usr/bin/env jython

#Java Dependencies
import javax.management.remote.JMXConnector;
import javax.management.remote.JMXConnectorFactory;
import javax.management.remote.JMXServiceURL;
import java.lang.management.ManagementFactory;

#Python Dependencies
import sys, cmd, socket

def usage():
    print """Usage:
    jmxclient.py -h
    jmxclient.py <connect_url> <jmx_attribute_path> <jmx_property>"""

class JMXClient:
    remote = None

    def connect(self, connect_url):
        if self.remote:
            return True

        #Establish Connection to JMX Server
        url = javax.management.remote.JMXServiceURL(connect_url);
        connector = javax.management.remote.JMXConnectorFactory.connect(url);
        self.remote = connector.getMBeanServerConnection();

    def getAttribute(self, mbean_path, attribute):
        """Query the mbean server for a specific attribute and return the
        result"""
        obn =  javax.management.ObjectName(mbean_path);
        result = self.remote.getAttribute(obn, attribute);

        return result    

if len(sys.argv) <= 1:
    usage()
    sys.exit(2)

if sys.argv[1] in ('-h', '--help'):
    usage()
    sys.exit(2)

if len(sys.argv) <> 4:
    usage()
    sys.exit(2)

(connect_url, mbean_path, attribute) = sys.argv[1:]

j = JMXClient()
j.connect(connect_url)
print j.getAttribute(mbean_path, attribute)   

好的,现在我正试图从兵马俑服务器获得一些属性.它使用jmxmp和url服务:jmx:jmxmp://0.0.0.0:9520.

所以,我正在运行我的脚本如下:

$ ./jmxclient.py service:jmx:jmxmp://localhost:9520 java.lang.ClassLoading LoadedClassCount
Traceback (innermost last):
  File "./jmxclient.py", line 87, in ?
  File "./jmxclient.py", line 61, in connect

java.net.MalformedURLException:java.net.MalformedURLException:不支持的协议:jmxmp

(由于某些被删除的评论,行号不相关)

如何添加对此jmxmp协议的支持？

我发现它似乎可以通过jmxremote_optional.jar启用.如何将此jar添加到我的jython(pref.不是系统范围的)？

更新:

正如所建议的那样,我从jmxremote-1_0_1-ri-bin-b58.zip参考实现中添加了jmxremote_optional.jar和jmxremote.jar :jython -Djava.endorsed.dirs=. -Dpython.path=.../jmxremote_optional.jar:.../jmxremote.jar:.../jmissl.jar jmxclient.py service:jmx:jmxmp://localhost:9520 java.lang.ClassLoading LoadedClassCount但仍然得到相同的错误.我确信jmxremote_optional.jar在classpath中,代码似乎与参考示例非常相似.

阅读api文档后,我尝试了以下更改:

url = javax.management.remote.JMXServiceURL('jmxmp', 'localhost', 9520);
connector = javax.management.remote.jmxmp.JMXMPConnector(url)
connector.connect()
self.remote = connector.getMBeanServerConnection();

这导致我另一个例外:

Traceback (innermost last):
  File "../src/jmxclient.py", line 87, in ?
  File "../src/jmxclient.py", line 61, in connect
        at com.sun.jmx.remote.opt.security.AdminClient.connectionOpen(AdminClient.java:209)

        at java.lang.reflect.Method.invoke(Method.java:597)
java.io.IOException: java.io.IOException: javax.management.remote.message.HandshakeBeginMessage

Jython版本是2.2,我不喜欢使用更高版本,因为这个脚本主要用在RHEL5盒子上,而且它们只有jython 2.2.1.

PS:标记问题已经回答了,因为我决定放弃并使用jmxterm或类似的工具,这些工具似乎都可以通过添加-Djava.endosed.dirs =/path/to/dir_with_jmxremote_optional /来使用jmxmp.但我仍然希望看到jython解决方案.

伙计,我读了大约7次这个帖子.....

无论如何,这就是我的想法.jmxmp协议未打包在标准J2SE运行时中.看到这个页面.报价:

注 - 如果要使用JMXMP连接器,请从http://java.sun.com/products/JavaManagement/download.html下载JSR 160 Reference Implementation ,并将jmxremote_optional.jar文件添加到类路径中.您将在JSR 160 Reference Implementation附带的JMX Remote API Tutorial中找到使用JMXMP连接器的示例.

我对jython并不熟悉,但看起来这篇文章应该会引起你的兴趣.
