一、JMX简介
JMX是一种JAVA的正式规范,它主要目的是让程序有被管理的功能,那么怎么理解所谓的“被管理”呢?试想你开发了一个软件(如WEB网站),它是在24小时不间断运行的,那么你可能会想要“监控”这个软件的运行情况,比如收到了多少数据,有多少人登录等等。或者你又想“配置”这个软件,比如现在访问人数比较多,你想把数据连接池设置得大一些。
当然,你也许会专门为这些管理来开发软件,但如果你借助JMX,则会发现创建这样的管理程序是如此简单。因为你无需为管理程序来开发界面,已经有通用的JMX管理软件,如MC4J,或者是用一般都附带提供的HTML网页来管理,你要做的仅仅是将自己要被管理和监控类的按照JMX规范修改一下即可。
中间件软件WebLogic的管理页面就是基于JMX开发的,而JBoss则整个系统都基于JMX构架。
二、监控Weblogic
下面介绍下如何通过jmx获取监控信息。
1、服务基本信息信息
/** * 构造函数 */ public WebLogicMiddlewareAdapter(JMXSession jmxSession) { currentTime = CommonUtils.getCurrentTime(); this.jmxSession = jmxSession; serverRuntime = (ObjectName) jmxSession.getAttribute(runtimeService, "ServerRuntime"); applicationRuntimes = (ObjectName[]) jmxSession.getAttribute(serverRuntime, "ApplicationRuntimes"); } /** * @see com.comtop.numen.monitor.collection.appservice.middleware.adapter.MiddlewareAdapter#getMiddleWareBaseInfomation() */ @Override public MiddleWareBaseInfoVO getMiddleWareBaseInfomation() { MiddleWareBaseInfoVO objWebLogic = new MiddleWareBaseInfoVO(); try { objWebLogic.setMiddlewareId(CommonUtils.getUUID()); objWebLogic.setWebContext(this.getWebConext()); if (JMXConstonts.JMX_COLLECT_EXTENDS.equals(jmxSession.getNodeInfoVO().getIsJmxExtends())) { // 获取进程ID objWebLogic.setMiddleWarePid(getMiddlewarePID()); } // 服务名称 objWebLogic.setServerName(jmxSession.getStringAttribute(runtimeService, "ServerName")); // Domain名称 ObjectName objConfig = (ObjectName) jmxSession.getAttribute(runtimeService, "DomainConfiguration"); objWebLogic.setDomainName(jmxSession.getStringAttribute(objConfig, "Name")); String strWLVersion=jmxSession.getStringAttribute(serverRuntime, "WeblogicVersion"); strWLVersion=strWLVersion.substring(strWLVersion.lastIndexOf("WebLogic"), strWLVersion.length()-1); objWebLogic.setRunnningState(jmxSession.getStringAttribute(serverRuntime, "State")); objWebLogic.setListenAddress(jmxSession.getStringAttribute(serverRuntime, "ListenAddress")); objWebLogic.setListenPort(jmxSession.getStringAttribute(serverRuntime, "ListenPort")); objWebLogic.setAdminServerHost(jmxSession.getStringAttribute(serverRuntime, "AdminServerHost")); objWebLogic.setAdminServerListenPort(jmxSession.getStringAttribute(serverRuntime, "AdminServerListenPort")); objWebLogic.setAdministrationPort(jmxSession.getStringAttribute(serverRuntime, "AdministrationPort")); objWebLogic .setOpenSocketsCurrentCount(jmxSession.getIntAttribute(serverRuntime, "OpenSocketsCurrentCount")); objWebLogic .setSocketsOpenedTotalCount(jmxSession.getIntAttribute(serverRuntime, "SocketsOpenedTotalCount")); objWebLogic.setRestartsTotalCount(jmxSession.getIntAttribute(serverRuntime, "RestartsTotalCount")); objWebLogic.setSSLListenAddress(jmxSession.getStringAttribute(serverRuntime, "SSLListenAddress")); long lTime = (Long) jmxSession.getAttribute(serverRuntime, "ActivationTime"); } catch (Exception e) { LOGGER.error("采集WebLogic信息出错" + e.getMessage()); return null; } return objWebLogic; }
