# Cluster Manager The **Cluster Manager** is a core Astral service installed directly on the host server as a Linux system service. It acts as the centralized control plane for deploying and managing Astral components, providing a standardized and automated approach to infrastructure provisioning. Upon installation, the Cluster Manager performs an initial **host assessment**, evaluating available resources such as CPU, memory, storage, and system characteristics. Based on this assessment, it generates a **recommended configuration** for the deployment of Astral components, taking into account the expected workload and architectural requirements of the environment. After the assessment is completed, the generated configuration is presented to the user for review. The user can validate and approve the recommended setup or adjust it according to operational needs. Once approved, the Cluster Manager orchestrates the installation of all required Astral components in a centralized and automated manner, ensuring consistency across the deployment. By combining host assessment, configuration recommendation, and automated deployment, the Cluster Manager reduces manual effort and minimizes configuration errors. This approach enables faster, repeatable, and reliable implementation of Astral instances, forming the foundation for scalable and well-governed SIEM deployments within the Inopli ecosystem. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
