您可以记录所有查询:

$ mongo
MongoDB shell version: 2.4.9
connecting to: test
> use myDb
switched to db myDb
> db.getProfilingLevel()
0
> db.setProfilingLevel(2)
{ "was" : 0, "slowms" : 1, "ok" : 1 }
> db.getProfilingLevel()
2
> db.system.profile.find().pretty()

来源:http://docs.mongodb.org/manual/reference/method/db.setProfilingLevel/

db.setProfilingLevel(2)表示“记录所有操作”。

我写了一个脚本，将打印出系统。当查询进来时，配置文件实时登录。如其他回答中所述，您需要首先启用日志记录。我需要这个，因为我正在使用Linux的Windows子系统，对于它，tail仍然不起作用。

尝试这个包来跟踪所有查询(没有oplog操作):https://www.npmjs.com/package/mongo-tail-queries

(免责声明:我写这个包正是为了这个需要)

将profilinglevel设置为2是记录所有查询的另一个选项。

很久以前有人问过这个问题，但这仍然可以帮助到一些人:

MongoDB profiler将所有查询记录在capped collection system.profile中。看这个:数据库分析器

Start mongod instance with --profile=2 option that enables logging all queries OR if mongod instances is already running, from mongoshell, run db.setProfilingLevel(2) after selecting database. (it can be verified by db.getProfilingLevel(), which should return 2) After this, I have created a script which utilises mongodb's tailable cursor to tail this system.profile collection and write the entries in a file. To view the logs I just need to tail it:tail -f ../logs/mongologs.txt. This script can be started in background and it will log all the operation on the db in the file.

我为系统编写的可尾游标代码。配置文件收集在nodejs中;它记录MyDb的每个集合中发生的所有操作和查询:

const MongoClient = require('mongodb').MongoClient;
const assert = require('assert');
const fs = require('fs');
const file = '../logs/mongologs'
// Connection URL
const url = 'mongodb://localhost:27017';

// Database Name
const dbName = 'MyDb';
//Mongodb connection

MongoClient.connect(url, function (err, client) {
   assert.equal(null, err);
   const db = client.db(dbName);
   listen(db, {})
});

function listen(db, conditions) {
var filter = { ns: { $ne: 'MyDb.system.profile' } }; //filter for query
//e.g. if we need to log only insert queries, use {op:'insert'}
//e.g. if we need to log operation on only 'MyCollection' collection, use {ns: 'MyDb.MyCollection'}
//we can give a lot of filters, print and check the 'document' variable below

// set MongoDB cursor options
var cursorOptions = {
    tailable: true,
    awaitdata: true,
    numberOfRetries: -1
};

// create stream and listen
var stream = db.collection('system.profile').find(filter, cursorOptions).stream();

// call the callback
stream.on('data', function (document) {
    //this will run on every operation/query done on our database
    //print 'document' to check the keys based on which we can filter
    //delete data which we dont need in our log file

    delete document.execStats;
    delete document.keysExamined;
    //-----
    //-----

    //append the log generated in our log file which can be tailed from command line
    fs.appendFile(file, JSON.stringify(document) + '\n', function (err) {
        if (err) (console.log('err'))
    })

});

}

对于python中使用pymongo的可尾游标，请参考以下代码，该代码过滤MyCollection并且只进行插入操作:

import pymongo
import time
client = pymongo.MongoClient()
oplog = client.MyDb.system.profile
first = oplog.find().sort('$natural', pymongo.ASCENDING).limit(-1).next()

ts = first['ts']
while True:
    cursor = oplog.find({'ts': {'$gt': ts}, 'ns': 'MyDb.MyCollection', 'op': 'insert'},
                        cursor_type=pymongo.CursorType.TAILABLE_AWAIT)
    while cursor.alive:
        for doc in cursor:
            ts = doc['ts']
            print(doc)
            print('\n')
        time.sleep(1)

注意:可尾随游标仅适用于有上限的集合。它不能直接用于记录集合上的操作，而是使用filter: 'ns': 'MyDb。MyCollection”

注意:我明白上面的nodejs和python代码可能对一些人没有太大的帮助。我只是提供了代码供参考

我在这个logrotate之后添加的另一个功能。

因为它的谷歌第一个答案… 对于版本3

$ mongo
MongoDB shell version: 3.0.2
connecting to: test
> use myDb
switched to db
> db.setLogLevel(1)
