监控Tomcat状态

Posted 2022-11-25 liyurui

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！
