How to run a mongo ping?

[Tim Haines]

Hi guys,

I'm trying to troubleshoot slowdowns that are occurring - observes occasionally taking 4 seconds to initialize etc.  One of the things I'd like to do is use mongo's ping command.  Can anyone suggest how I might be able to use Meteor's mongo connection in order to call the ping command?

http://docs.mongodb.org/manual/reference/command/ping/

I see the mongo npm module has it available as Admin.ping, but I'm not sure how to call it: https://github.com/mongodb/node-mongodb-native/blob/master/lib/mongodb/admin.js#L100

Cheers,

Tim.

This might work.

col = new Meteor.Collection('ffg');

  Meteor.setTimeout(function() {

    var mongo = Npm.require('mongodb');

    var db = col.find()._mongo.db;

    console.log(db);

    var adminDb = new mongo.Admin(db);

    adminDb.ping();

  }, 1000);

Not tested.

You might need use my npm package to get mongodb npm module.
