Overview of this book

MongoDB is a high-performance and feature-rich NoSQL database that forms the backbone of the systems that power many different organizations – it’s easy to see why it’s the most popular NoSQL database on the market. Packed with many features that have become essential for many different types of software professionals and incredibly easy to use, this cookbook contains many solutions to the everyday challenges of MongoDB, as well as guidance on effective techniques to extend your skills and capabilities. This book starts with how to initialize the server in three different modes with various configurations. You will then be introduced to programming language drivers in both Java and Python. A new feature in MongoDB 3 is that you can connect to a single node using Python, set to make MongoDB even more popular with anyone working with Python. You will then learn a range of further topics including advanced query operations, monitoring and backup using MMS, as well as some very useful administration recipes including SCRAM-SHA-1 Authentication. Beyond that, you will also find recipes on cloud deployment, including guidance on how to work with Docker containers alongside MongoDB, integrating the database with Hadoop, and tips for improving developer productivity. Created as both an accessible tutorial and an easy to use resource, on hand whenever you need to solve a problem, MongoDB Cookbook will help you handle everything from administration to automation with MongoDB more effectively than ever before.

Signing up for MMS and setting up an MMS monitoring agent

MMS is a cloud-based or on-premise service that enables you to monitor your MongoDB cluster. The on-premise version is available with an enterprise subscription only. It gives you one central place that lets the administrators monitor the health of the server instances and the boxes on which the instances are running. In this recipe, we will see what the software requirements are and how to set up MMS for Mongo.

Getting ready

We will be starting a single instance of mongod, which we will use for monitoring purposes. Refer to the recipe Installing single node MongoDB from Chapter 1, Installing and Starting the Server to start a MongoDB instance and connect to it from a Mongo shell. The monitoring agent used for sending the statistics of the mongo instance to the monitoring service uses Python and pymongo. Refer to the recipe Connecting to a single node using a Python client in Chapter 1, Installing and Starting the Server to learn more...
