Cloudera Manager is an end-to-end application for managing CDH clusters. Cloudera Manager provides granular visibility into and control over every part of the CDH cluster—empowering operators to improve performance, enhance quality of service, increase compliance, and reduce administrative costs. With Cloudera Manager, you can easily deploy and centrally operate the complete CDH stack and other managed services. The application automates the installation process, reducing deployment time from weeks to minutes; gives you a cluster-wide, real-time view of hosts and services running; provides a single, central console to enact configuration changes across your cluster; and incorporates a full range of reporting and diagnostic tools to help you optimize performance and utilization. Cloudera Manager also provides an API you can use to automate cluster operations.
The following topics from the core Cloudera Enterprise documentation library can help you understand Cloudera Manager concepts and how to use Cloudera Manager to manage, monitor, and upgrade your deployment. They are listed by broad category:

Installing and Upgrading
Managing CDH using Cloudera Manager
Cloudera Manager provides tools you can use to manage the services, hosts, and applications deployed in your cluster.
Monitoring CDH using Cloudera Manager
You can use Cloudera Manager to monitor many aspects of the performance of the services and hosts in your cluster. You can define alerts that send notifications in response to conditions you specify.
Managing CDH using the Cloudera Manager API
The Cloudera Manager API provides configuration and service lifecycle management, service health information and metrics, and allows you to configure Cloudera Manager itself. The API is served on the same host and port as the Cloudera Manager Admin Console, and does not require an extra process or extra configuration. The API supports both HTTP Basic Authentication and Kerberos (SPNEGO), accepting the same users and credentials as the Cloudera Manager Admin Console. Kerberos authentication is only supported from clients (such as curl) that can use SPNEGO. The Cloudera Manager Swagger and Python clients do not support SPNEGO.
