To check the memory usage of the JVM, you can use the following method:<\/p>\n

    \n
  1. Utilize the jcmd command in JDK. Enter jcmd VM.native_memory summary in the command line, where is the ID of the JVM process. This command will display a summary of the JVM’s memory usage, including heap memory, non-heap memory, and metaspace usage.<\/li>\n
  2. Utilize the jstat command in the JDK. Input jstat -gc in the command line, where is the ID of the JVM process. This command will display the garbage collection status of the JVM, including the usage of heap memory (such as Eden space, Survivor space, and old generation).<\/li>\n
  3. Utilize the jmap command in the JDK. Type jmap -heap in the command line, where is the ID of the JVM process. This command will display the heap memory usage of the JVM, including the total capacity, used space, and free space.<\/li>\n
  4. Utilize the VisualVM tool within the JDK. VisualVM is a graphical tool that allows for real-time monitoring and analysis of JVM memory usage. Download and install VisualVM from https:\/\/visualvm.github.io\/, then use it to connect to a running JVM process in order to view detailed information on memory usage.<\/li>\n<\/ol>\n

    These methods can help you view the memory usage of the JVM in order to perform performance analysis and optimization.<\/p>\n","protected":false},"excerpt":{"rendered":"
