MongoDB db.serverStatus() gives error when running using tunnel that is targeted to api.cloudfoundry.com - mongodb

Question

Following is the console session...
C:\Users\xxx>vmc tunnel myMongoDB
Getting tunnel connection info: OK
Service connection info:
username : uuuu
password : pppp
name : db
url : mongodb://uuuu:pppp#172.30.xx.xx:25200/db
Starting tunnel to myMongoDB on port 10000.
1: none
2: mongo
3: mongodump
4: mongorestore
Which client would you like to start?: 2
Launching 'mongo --host localhost --port 10000 -u uuuu -p pppp db'
MongoDB shell version: 2.0.6
connecting to: localhost:10000/db
> db.serverStatus()
{ "errmsg" : "need to login", "ok" : 0 }
>
Which credentials should I use to login (assuming should use db.auth) to get rid of the error "{ "errmsg" : "need to login", "ok" : 0 }".
When I run the same in micro CF on my machine it works ok and gives me the expected output.
P.S. I'm trying this to get to know the current connections on my application, written in node.js. Trying to debug some issues with connections to the DB. If there is any other alternative that I can use please suggest that as well.

Answer 1

this should work! Not sure why your tunnel isn't connecting, my immediate suggestion is to try another instance of MongoDB and see if the same error occurs.
If you are trying to inspect the bound services on you node.js app you should be able to inspect them in the VCAP_SERVICES environment variable. For example;
var http = require('http');
var util = require('util');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.write(util.inspect(process.env.VCAP_SERVICES));
res.write("\n\n************\n\n");
res.end(util.inspect(req.headers));
}).listen(3000);
This code is currently running at http://node-headers.cloudfoundry.com/ to serve as an example. However, mongodb connections for node.js applications should automatically configure to the bound service. If this does not work for you, then please do let me know.
