MongoDB ships with a web-based administrative tool. You can see this tool by going to http://localhost:28017/

You can see a bunch of stuff on the administrative tool screen. here is a partial image.

MongoDB: web-based administrative tool

There are a bunch of links that you can click as well. If you click on any of the links on top

List all commands | Replica set status</p> <p>Commands: buildInfo cursorInfo features hostInfo isMaster listDatabases replSetGetStatus serverStatus top

You get the following message

REST is not enabled.  use --rest to turn on.
check that port 28017 is secured for the network too.

So here is how you can fix that, open the config file mongod.cfg

In my case, I have the following there, yours will look different

logpath=C:NoSQLmongodblogmongo.log 
dbpath=C:NoSQLmongodbdata

Add the line rest=true at the bottom, so that it becomes

logpath=C:NoSQLmongodblogmongo.log 
dbpath=C:NoSQLmongodbdata
rest=true

Here is what it looks like when opened in notepad.

mongod.cfg

Save it, restart the MongoDB service. If you want to learn how to have MongoDB run as a service on Windows, take a look at Creating MongoDB as a service on Windows 8, the process should be the same for Windows 7

If you click on List all commands you will see a list of all the commands. Here is an image of a partial list

MongoDB: List all commands

Scroll down to hostinfo and click on it you will see the following output

{ "system" : { "currentTime" : { "$date" : "Sun Feb 24 09:43:31 2013" },
    "hostname" : "Denis",
    "cpuAddrSize" : 64,
    "memSizeMB" : 4095,
    "numCores" : 2,
    "cpuArch" : "x86_64",
    "numaEnabled" : false },
  "os" : { "type" : "Windows",
    "name" : "Microsoft Windows 8",
    "version" : "6.2 (build 9200)" },
  "extra" : { "pageSize" : 4096 } }

You can now bookmark some of the most used commands, hostinfo for example is http://localhost:28017/hostInfo?text=1

Go ahead and play around with the tool, check out all the links and also explore some of the commands that are listed
