Database Commands
Database commands allow you to perform a wide range of diagnostic and administrative
tasks with the Node.js driver. For example, the
dbStats command returns
storage statistics for a given database. Use the command
function to access
database commands.
// set up a command function
function getDbStats(db, callback) {
db.command({'dbStats': 1}, function(err, results) {
console.log(results);
callback();
});
};
// use the function
const MongoClient = require('mongodb').MongoClient;
const assert = require('assert');
// Connection URL
const url = 'mongodb://localhost:27017';
// Database Name
const dbName = 'myproject';
// Create a new MongoClient
const client = new MongoClient(url);
// Use connect method to connect to the Server
client.connect(function(err, client) {
assert.equal(null, err);
console.log("Connected correctly to server");
const db = client.db(dbName);
getDbStats(db, function() {
client.close();
});
});
