jvisualvm是jdk自帶的監測工具,在windows命令行中即可啓java
啓動命令:shell
Microsoft Windows [Version 6.2.9200] (c) 2012 Microsoft Corporation. All rights reserved. C:\Users\my>jvisualvm C:\Users\my> The launcher has determined that the parent process has a console and will reuse it for its own console output. Closing the console will result in termination of the running program. Use '--console suppress' to suppress console output. Use '--console new' to create a separate console window.
啓動以後能夠查看本地運行的java進程windows
配置服務器端服務器
jvisualvm 鏈接服務器有兩種方式ide
1.Jstatd工具
2.JMX命令行
配置jstatd以後能夠鏈接遠程服務器,監控全部的java進程code
my.policyserver
grant codebase "file:${java.home}/../lib/tools.jar" { permission java.security.AllPermission; };
JMX能夠監控特定的應用進程進程
jstatd -J-Djava.security.policy=/home/my/spider/test/my.policy -J-Djava.rmi.server.logCalls=true
配置以後發現,本地jvisualvm比較佔用內存,響應比較慢。
jmx鏈接不成功
