VisualVM监控远程服务SpringBoot

1.启动参数

java -jar \
-Djava.rmi.server.hostname=192.168.14.11 \
-Dcom.sun.management.jmxremote \
-Dcom.sun.management.jmxremote.port=2622 \
-Dcom.sun.management.jmxremote.ssl=false \
-Dcom.sun.management.jmxremote.access.file=/usr/jmxremote.access \
-Dcom.sun.management.jmxremote.password.file=/usr/jmxremote.password \
user.jar

-Djava.rmi.server.hostname 远程服务的地址

需要设置文件权限

chmod 0400 jmxremote.password

2.visual gc提示not supported for this jvm

在自己的jdk里 vim jdk/jre/lib/security/java.policy 加入permission java.security.AllPermission;

如下：

grant {?
// Allows any thread to stop itself using the java.lang.Thread.stop()
// method that takes no argument.
// Note that this permission is granted by default only to remain
// backwards compatible.
// It is strongly recommended that you either remove this permission
// from this policy file or further restrict it to code sources
// that you specify, because Thread.stop() is potentially unsafe.
// See the API specification of java.lang.Thread.stop() for more
? ? ? ? // information.
permission java.lang.RuntimePermission "stopThread";

// allows anyone to listen on un-privileged ports
permission java.net.SocketPermission "localhost:1024-", "listen";

// "standard" properies that can be read by anyone

permission java.util.PropertyPermission "java.version", "read";
permission java.util.PropertyPermission "java.vendor", "read";
permission java.util.PropertyPermission "java.vendor.url", "read";
permission java.util.PropertyPermission "java.class.version", "read";
permission java.util.PropertyPermission "os.name", "read";
permission java.util.PropertyPermission "os.version", "read";
permission java.util.PropertyPermission "os.arch", "read";

permission java.util.PropertyPermission "java.specification.version", "read";
permission java.util.PropertyPermission "java.specification.vendor", "read";
permission java.util.PropertyPermission "java.specification.name", "read";

permission java.util.PropertyPermission "java.vm.specification.version", "read";
permission java.util.PropertyPermission "java.vm.specification.vendor", "read";
permission java.util.PropertyPermission "java.vm.specification.name", "read";
permission java.util.PropertyPermission "java.vm.version", "read";
permission java.util.PropertyPermission "java.vm.vendor", "read";
permission java.util.PropertyPermission "java.vm.name", "read";
permission java.security.AllPermission;
};

3.启动 jstatd -J-Djava.security.policy=jstatd.all.policy

jstatd -J-Djava.security.policy=jstatd.all.policy -p 端口xxx

Could not bind //:xxx/JStatRemoteHost to RMI Registry
