1、free -m 查看内存使用情况,top命令查看进程PID: 2、使用jmap命令导出head dump文件: jmap -dump:live,format=b,file=m.hprofile6534 6534 其中:m.hprofile6534是dump信息导出的文件名称,6534是进程号 3、使用JDK自带的VisualVM工具分析: 本地JDK安装目录》bin目录下找到jvisualvm.exe, 双加打开: 加载下载...
比如 -Xmx100m -XX: +HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=D: \m.hprof 我们在我们测试的测试配置上添加上面的配置: 启动程序等待一会儿: 3、显示堆内存相关的信息 3.1、jmap -heap pid AI检测代码解析 Attaching to process ID 10452, please wait... Debugger attached successfully. Server compiler...
-l 输出main类或Jar的全限名 -v输出传入JVM的参数 比如下面: root@ubuntu :/# jps -m -l 2458 org.artifactory.standalone.main.Main/usr/local/artifactory-2.2.5/etc/jetty.xml 29920 com.sun.tools.hat.Main -port 9998/tmp/dump.dat 3149 org.apache.catalina.startup.Bootstrap start 30972 sun.too...
jmap导出java vm jmap导出dump比实际小 有时候通过./jmap -heap [pid] 命令发现JVM堆内存使用900M,某个时刻显示新生代和老年代的使用之和600M,本想看看600M是什么对象占的,通过jmap dump生成dump文件后,发现used 内存占比比较小,只有200M, free内存占比很高,很奇怪。经过官网文档,发现了端倪。 Find out more...
G1HeapRegionSize = 0 (0.0MB)(G1区块的大小, 取值为1M至32M. 其取值是要根据最小Heap大小划分出2048个区块. With G1 the Java heap is subdivided into uniformly sized regions. This sets the size of the individual sub-divisions. The default value of this parameter is determined ergonomically base...

当然是，其他的也是一样。
