如何验证从express.js服务器到mongo db的每个查询日志？

Question

How can I verify every query from express.js server to mongo db?

I looked manage-the-database-profiler I had set profile level as db.setProfilingLevel(2,200) . At my page is calling following mongo DB using mongoose like following

mycollection.findOne({MyId: 1}, function(err, data){

    })

When I look log file, there's no access to "mycollection". Also, the log file sometime do contains query on some of my page like following.

2014-07-30T13:11:59.258-0700 [conn33] query myDB.myOtherCollection query: { MyID: 100 } planSummary: COLLSCAN ntoskip:0 nscanned:850 nscannedObjects:850 keyUpdates:0 numYields:7 locks(micros) r:6101 nreturned:0 reslen:20 3ms

So what is a way to show all query log to mongo database?

Answer 1

由于您使用的是猫鼬，因此可以通过启用调试来查看执行的查询。

mongoose.set('debug', true)

Answer 2

db.setProfilingLevel has an optional level argument that, when set to 2, records all operations in the system.profile collection of the database, not in the log file. The slowMS argument determines how slow a query must be before it is logged to the log file.

If you want to closely monitor activity in your collections, consider using MMS for monitoring as it exposes a lot of useful usage, performance, and profiling information in a more friendly format than system.profile .

Answer 3

如果将第二个参数slowMS设置为1ms，这将记录所有耗时超过1ms的查询-这几乎是所有查询。
