How to retrieve available RAM from Windows command line?
提问by Mike
Is there a command line utility within Windows or third-party program that can retrieve available RAM on a machine? (Since I don't believe this can be done in pure JAVA, since it is run within a virtual machine, that has preset / allocated RAM)?
Windows 或第三方程序中是否有命令行实用程序可以检索机器上的可用 RAM？（因为我不相信这可以在纯 JAVA 中完成，因为它是在虚拟机中运行的，该虚拟机具有预设/分配的 RAM）？

There is a whole bunch of useful low level tools from SysSnternals.
SysSnternals 提供了一大堆有用的低级工具。
And psinfomay be the most useful.
并且psinfo可能是最有用的。
I used the following psinfo switches:
我使用了以下 psinfo 开关：
-h Show installed hotfixes.
-d Show disk volume information.
Sample output is this:
示例输出是这样的：
c:> psinfo \development -h -d

Bit old but I wanted to know similar. Just adding the solution I came across since IMO the best answer came from Everardo w/ Physical Memory
有点老，但我想知道类似的。只是添加我遇到的解决方案，因为 IMO 最好的答案来自 Everardo w/Physical Memory
wmic OS get FreePhysicalMemory /Value
wmic OS get FreePhysicalMemory /Value
This lead me to look deeper into wmic... Keep in mind Free Physical Memory is not the type to look at.
这让我更深入地了解 wmic... 请记住，空闲物理内存不是要查看的类型。
wmic OS get FreePhysicalMemory,FreeVirtualMemory,FreeSpaceInPagingFiles /VALUE
wmic OS get FreePhysicalMemory,FreeVirtualMemory,FreeSpaceInPagingFiles /VALUE
This returns something like...
这将返回类似...
FreePhysicalMemory=2083440
FreeSpaceInPagingFiles=3636128
FreeVirtualMemory=842124

This cannot be done in pure java. But you can run external programs using java and get the result.
这不能在纯 Java 中完成。但是您可以使用 java 运行外部程序并获得结果。
Process p=Runtime.getRuntime().exec("systeminfo");
Scanner scan=new Scanner(p.getInputStream());
while(scan.hasNext()){
String temp=scan.nextLine();
if(temp.equals("Available Physical Memmory")){
System.out.println("RAM :"temp.split(":")[1]);
break;
}
}

Try MemLog. It does the job perfectly and quickly.
试试 MemLog。它可以完美而快速地完成工作。
Download via one of many mirrors, e.g. this one: SoftPedia page for MemLog.
(MemLog's author has a web site. But this is down some times. Wayback machine snapshot here.)
通过许多镜像之一下载，例如这个：MemLog 的 SoftPedia 页面。
（MemLog 的作者有一个网站。但有时会关闭。Wayback机器快照在这里。）

Here is a pure Javasolution actually:
Java实际上，这是一个纯粹的解决方案：
public static long getFreePhysicalMemory()
{
com.sun.management.OperatingSystemMXBean bean =
(com.sun.management.OperatingSystemMXBean)
java.lang.management.ManagementFactory.getOperatingSystemMXBean();
return bean.getFreePhysicalMemorySize();
}
