jmx 远程监控 jvm及weblogic

这两天写了一些jmx 监控 weblogic 及 jvm 的代码。内容简单。代码都写在一个按钮的事件里。主要完成的功能就是远程监控jvm 及weblogic 的一些使用情况。功能单一。也可以改一下内容进行手动远程gc。oracle weblogic 技术讨论群49303854

//初始监控化信息表头
DefaultTableModel mode = new DefaultTableModel();
mode.addColumn("IP");
mode.addColumn("当前堆大小");
mode.addColumn("自由内存");
mode.addColumn("内存使用率");
mode.addColumn("空闲线程");
mode.addColumn("总线程");
mode.addColumn("队列长度");
mode.addColumn("等待服务队列");
mode.addColumn("每秒处理请求数");
//weblogic 服务器信息

//空闲线程：指占用了内存，但没有执行任务的线程
int ideThread = Integer.parseInt(String.valueOf(mbeanServerConn.getAttribute(threadPoolRuntime, "ExecuteThreadIdleCount")));

//总线程数
int totalThread = Integer.parseInt(String.valueOf(mbeanServerConn.getAttribute(threadPoolRuntime, "ExecuteThreadTotalCount")));
//等待请求的队列
int queueLength = Integer.parseInt(String.valueOf(mbeanServerConn.getAttribute(threadPoolRuntime, "QueueLength")));

//用户请求执行等待队列
int waitThreadCount = Integer.parseInt(String.valueOf(mbeanServerConn.getAttribute(threadPoolRuntime, "PendingUserRequestCount")));

//每秒处理的线程数比率
String throuhput = mbeanServerConn.getAttribute(threadPoolRuntime, "Throughput").toString();

//加入row 中
Object[] row = {hostName,memoryMaxSize,memoryFreeSize,memoryPer,ideThread,totalThread,queueLength,waitThreadCount,throuhput};
mode.addRow(row);
