监控运行中jar包的jvm信息

开启jar包运行端口修改java -jar命令加入如下命令参数（端口可以任意，但不要与其他应用端口冲突）

-Dcom.sun.management.jmxremote.port=8996-Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false

下面脚本是启动jar的脚本功能在于启动jar 并且把属性传入到main函数中初始化作用仅供参考

#MonCenter start shell#set fileformat=unixps -ef | grep mon.jar | grep -v grep | awk '{print $2}' | xargs kill -9pros(){propties=''arr=()i=0while read line; do    arr[i++]=$linedone < $1for data in ${arr[@]}do     propties="$propties""$data""\r"done}pros /soc/etc/jmxremote.propertiesjmxremote=$proptiesecho "======jmxremote.properties========="echo $jmxremote#start MonCenternohup java -Xmx200m -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/soc/var/ -Djava.library.path=/soc/lib/sigar/ -Dcom.sun.management.jmxremote.port=8996 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false  -jar /soc/lib/mon.jar $jmxremote >/soc/var/nli/monstart.file 2>&1 &tail -100f /soc/var/nli/monstart.file

获取jmx连接方法 url格式例如 String jmxUrl = "service:jmx:rmi:///jndi/rmi://" + ip + ":" + port+ "/jmxrmi";

 /**     * 获得MBeanServer 的连接     *      * @param jmxUrl     * @return     * @throws IOException     */    public static JMXConnector getMBeanServerConnection(String jmxUrl)        throws IOException {        JMXServiceURL url = new JMXServiceURL(jmxUrl);        JMXConnector jmxc = null;        try{            jmxc = JMXConnectorFactory.connect(url, null);        }catch (Exception e) {            logger.error("getMBeanServerConnection JMXConnector Exception ");            return null;        }                return jmxc;    }

获取连接

MBeanServerConnection mbsc = jmxConnection.getMBeanServerConnection();

获取线程信息例子

    /**     * 获得jvm 线程信息     */        public  void getThreadInfo(JvmInfoBean jib,MBeanServerConnection jmxConnection){        ThreadMXBean op;        try {            op = ManagementFactory.newPlatformMXBeanProxy(jmxConnection, "java.lang:type=Threading", ThreadMXBean.class);            System.out.println("ObjectName="+op.getObjectName());              System.out.println("仍活动的线程总数="+op.getThreadCount());              System.out.println("峰值="+op.getPeakThreadCount());              System.out.println("线程总数（被创建并执行过的线程总数）="+op.getTotalStartedThreadCount());              System.out.println("当初仍活动的守护线程（daemonThread）总数="+op.getDaemonThreadCount());              //            long[] deadlockedIds = op.findDeadlockedThreads();//            if(deadlockedIds != null && deadlockedIds.length > 0){  //                ThreadInfo[] deadlockInfos = op.getThreadInfo(deadlockedIds);  //                System.out.println("死锁线程信息:");  //                System.out.println("\t\t线程名称\t\t状态\t\t");  //                for(ThreadInfo deadlockInfo : deadlockInfos){  //                    System.out.println("\t\t"+deadlockInfo.getThreadName()+"\t\t"+deadlockInfo.getThreadState()  //                            +"\t\t"+deadlockInfo.getBlockedTime()+"\t\t"+deadlockInfo.getWaitedTime()  //                            +"\t\t"+deadlockInfo.getStackTrace().toString());  //                }  //            }          } catch (IOException e) {            e.printStackTrace();        }    }

其他参数可以通过 jconsole进行获取
