OpsCenter: An Architecture Overview

OpsCenter is a tool used to manage and monitor Cassandra and DataStax Enterprise clusters. It has three main components: User Interface (UI), OpsCenter Daemon, and OpsCenter Agent. The UI is self-contained in the browser and interacts with the API exposed by the OpsCenter Daemon. The daemon serves the UI component, exposes a REST API for interaction, and gathers cluster information via thrift or agents. The agent collects node information, manages performance data, and acts as a proxy for Cassandra's JMX management functions. Encryption of communication is enabled by default through SSL, with optional support for other types of communication.
