如何使用 Node.js 检查 ram 的当前使用情况？ （Discord.js 机器人）
How can i check the current usage of ram with Node.js? (Discord.js Bot)
我想创建一个名为 _ram 的命令，它应该显示机器人 ram 的当前使用情况。我已经尝试过这些东西：
${client.performance.memory} //(Says memory is not defined)
${window.performance.memory} //(Window is not defined)
有什么显示方法吗？
如果你想知道你的Node.js进程使用了多少内存，你可以查询：
process.memoryUsage().heapUsed / 1024 / 1024;
它将以字节为单位输出您的进程使用的内存。它不会显示 Node.js 使用的实际内存，因为在这种情况下您还需要考虑 Node.js 垃圾收集器。
您必须使用：process.memoryUsage()其中 returns 一个以字节为单位描述进程内存使用情况的对象。
{
rss: 4935680,
heapTotal: 1826816,
heapUsed: 650472,
external: 49879
}
heapTotal and heapUsed refer to V8's memory usage. external refers to
the memory usage of C++ objects bound to JavaScript objects managed by
V8. rss, Resident Set Size, is the amount of space occupied in the
main memory device (that is a subset of the total allocated memory)
for the process, which includes the heap, code segment and stack.
var os = require('os');
var usedMemory = os.totalmem() -os.freemem(), totalMemory = os.totalmem();
var getpercentage =
((usedMemory/totalMemory) * 100).toFixed(2) + '%'
console.log("Memory used in GB", (usedMemory/ Math.pow(1024, 3)).toFixed(2))
console.log("Used memory" , getpercentage);
