问题描述
使用jmx nodeJs包桥接来自nodeJs的kafka应用程序并与之通信时遇到问题（请参见https://www.npmjs.com/package/jmx）。
我的代码：
var jmx = require('jmx');
var java = require('java');
java.import("javax.management.remote.JMXConnectorFactory");
var System = java.import('java.lang.System');
System.setProperty('sun.rmi.transport.connectionTimeout','500');
System.setProperty('sun.rmi.transport.tcp.handshakeTimeout','500');
System.setProperty('sun.rmi.transport.tcp.responseTimeout','500');
System.setProperty('sun.rmi.transport.tcp.readTimeout','500');
var host = "192.168.xx.xx";
var port = 5600;
var jmxrmi = 'service:jmx:rmi:///jndi/rmi://' + host + ':' + port + '/jmxrmi';
var client = jmx.createClient({
service:jmxrmi
});
client.on('error',function (e) {
console.log('Error: JMX at %s:%d',host,port,e);
client.disconnect();
});
client.on('disconnect',function (err) {
console.log('Successfully disconnected from client.');
});
client.on('connect',function() {
console.log('Successfully connected to client.');
client.disconnect();
});
client.connect();
