This is our last chapter. Here, you will learn how to manage and control the MongoDB instances, including replica sets, shards, and standalone mongod instances. We will review monitoring, profiling, and reporting utilities in MongoDB. Also, we will study the diagnostic strategies that help database administrators prevent database engine failures. Step-by-step, we will learn how to work with these utilities.
Monitoring is one of the critical tasks of database administration. Using correct monitoring tools based on the situation and context can help database administrators to provide a readily-available database engine. For instance, by configuring the correct alert messages in database high overload, the database administrator can follow an appropriate method to add a new node to the cluster or upgrade the existing server.
The good news is that MongoDB has many monitoring and profiling tools. In the previous chapters, we used some of these tools, such as profiling. In order to monitor the database, you can use different approaches based on your context. If you want to have a real-time report of a database or check the currently running tasks or read/write operations, you can use the built-in database commands or utilities.
On the other hand, in certain situations when you want to diagnose a database, you can simply use the profiling tools. These tools come in...
In this section, we will go through the web-based tools and utilities to manage and control the MongoDB instance. Tools in this category are generally easy to use and configure. Using a straightforward installation, you can configure the tools and then check the reports online using a web page or mobile application.
