Mongodb如何对数据库中的所有集合执行collstats

const MongoClient = require('mongodb').MongoClient;

const url = 'mongodb://localhost:27017';  // Mongodb连接地址
const databaseName = 'your_database_name';  // 要操作的数据库名称

MongoClient.connect(url, function(err, client) {
  if (err) {
    console.error('Failed to connect to MongoDB:', err);
    return;
  }

  const db = client.db(databaseName);
  db.listCollections().toArray(function(err, collections) {
    if (err) {
      console.error('Failed to fetch collections:', err);
      return;
    }

    collections.forEach(function(collection) {
      const collName = collection.name;
      const coll = db.collection(collName);
      coll.stats(function(err, stats) {
        if (err) {
          console.error(`Failed to get stats for collection ${collName}:`, err);
        } else {
          console.log(`Stats for collection ${collName}:`, stats);
        }
      });
    });

    client.close();
  });
});
