方法一:开发java监控页面
[root@localhost ~]# mkdir /usr/local/tomcat8/webapps/memtest/
[root@localhost ~]# vim /usr/local/tomcat8/webapps/memtest/meminfo.jsp
<%
Runtime rtm = Runtime.getRuntime();
long mm = rtm.maxMemory()/1024/1024;
long tm = rtm.totalMemory()/1024/1024;
long fm = rtm.freeMemory()/1024/1024;
out.println("JVM memory detail info :<br>");
out.println("Max memory:"+mm+"MB"+"<br>");
out.println("Total memory:"+tm+"MB"+"<br>");
out.println("Free memory:"+fm+"MB"+"<br>");
out.println("Available memory can be used is :"+(mm+fm-tm)+"MB"+"<br>");
%>
方法二:使用jps命令进行监控
root@localhost ~]# jps -lvm
80106 sun.tools.jps.Jps -lvm -Dapplication.home=/usr/local/java -Xms8m
79788 org.apache.catalina.startup.Bootstrap start -Djava.util.logging.config.file=/usr/local/tomcat8/conf/logging.propertie
s -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djdk.tls.ephemeralDHKeySize=2048 -Djava.protocol.handler.pkgs=org.apache.catalina.webresources -Dcatalina.base=/usr/local/tomcat8 -Dcatalina.home=/usr/local/tomcat8 -Djava.io.tmpdir=/usr/local/tomcat8/temp
方法三:Tomcat远程监控功能
修改配置文件,开启远程监控
在windows上监控tomcat
注意:windwos需要安装jdk环境!
