如下代码可以监控tomcat中jvm不同代的内存使用情况：
<%@ page import="java.lang.management.*" %><%@ page import="java.util.*" %><html><head> <title>JVM Memory Monitor</title></head><body><% Iterator iter = ManagementFactory.getMemoryPoolMXBeans().iterator(); while (iter.hasNext()) { MemoryPoolMXBean item = (MemoryPoolMXBean) iter.next();%><table border="0" width="100%"><tr><td colspan="2" align="center"><h3>Memory MXBean</h3></td></tr><tr><td width="200">Heap Memory Usage</td><td><%=ManagementFactory.getMemoryMXBean().getHeapMemoryUsage()%></td></tr><tr> <td>Non-Heap Memory Usage</td> <td><%=ManagementFactory.getMemoryMXBean().getNonHeapMemoryUsage()%></td></tr><tr><td colspan="2"> </td></tr><tr><td colspan="2" align="center"><h3>Memory Pool MXBeans</h3></td></tr><% Iterator iter = ManagementFactory.getMemoryPoolMXBeans().iterator(); while (iter.hasNext()) { MemoryPoolMXBean item = (MemoryPoolMXBean) iter.next();%><tr><td colspan="2"><table border="0" width="100%" style="border: 1px #98AAB1 solid;"><tr><td colspan="2" align="center"><b><%= item.getName() %></b></td></tr><tr><td width="200">Type</td><td><%= item.getType() %></td></tr><tr><td>Usage</td><td><%= item.getUsage() %></td></tr><tr><td>Peak Usage</td><td><%= item.getPeakUsage() %></td></tr><tr><td>Collection Usage</td><td><%= item.getCollectionUsage() %></td></tr></table></td></tr><tr><td colspan="2"> </td></tr><%}%></table></body></html>
