Prism Central

The Nutanix management plane that provides a single console across multiple clusters, hosting automation features such as Playbooks, Calm, and runbook execution alongside inventory and monitoring.

Related: Prism Element, Categories
Prism Element

The per-cluster management interface in Nutanix, responsible for local cluster configuration, storage containers, and health, and registered as a resource that Prism Central can manage.

Related: Prism Central, Registered Cluster
Categories

Key-value metadata labels assigned to VMs and other entities, used to scope Playbooks, policies, and reporting to specific groups of resources.

Related: Playbook Trigger, Policy
Playbook

An event-driven automation definition in Prism Central that pairs a trigger with a sequence of actions, optionally gated by approval, to respond automatically to changes in the environment.

Related: Playbook Trigger, Playbook Action, Approval Policy
Playbook Trigger

The event or condition that starts a Playbook, such as a VM power state change, an alert, a category change, or a scheduled time.

Related: Playbook, Event Trigger, Alert
Playbook Action

A single executable step inside a Playbook, such as sending email, running a script, invoking a REST API, or performing a VM operation.

Related: Playbook, X-Play, Webhook
Approval Policy

A setting that pauses a Playbook or runbook before sensitive actions and requires a designated approver to accept or reject the pending execution.

Related: Playbook, Runbook Execution
Event Trigger

A Playbook trigger type that fires when a monitored system event occurs, for example a VM being created or an alert being raised.

Related: Alert Trigger, Playbook Trigger
Alert Trigger

A Playbook trigger that responds to a specific Prism Central alert, commonly used to remediate conditions such as low disk space or a failed component.

Related: Alert, Event Trigger
Calm

The Nutanix self-service and application lifecycle management component that models multi-tier applications as blueprints and deploys them through projects and environments.

Related: Blueprint, Project, Marketplace
Blueprint

A reusable application definition in Calm describing services, their VM or container specifications, dependencies, and lifecycle actions used at deploy, start, stop, and delete.

Related: Service, Lifecycle Action, Runbook
Project

A Calm construct that bundles users, roles, quotas, clusters, and networks so that self-service deployments are constrained to approved infrastructure and accountable to an owner.

Related: Quota, Role-Based Access Control, Blueprint
Service

A single tier or component within a Calm blueprint, defining its VM template, resource sizing, and scripts that run during the application lifecycle.

Related: Blueprint, Lifecycle Action
Lifecycle Action

A hook attached to a blueprint or service that executes at a defined phase such as pre-create, post-create, or pre-delete, typically running a script or task.

Related: Service, Blueprint, Task
Marketplace

The Nutanix catalog of prebuilt blueprints and applications that users can deploy through self-service, subject to their project permissions and quotas.

Related: Blueprint, Project
Quota

A limit on resource consumption, such as vCPUs, memory, or storage, enforced per project to prevent self-service deployments from exhausting cluster capacity.

Related: Project
Runbook

A reusable sequence of automated and manual steps executed on demand or on a schedule, used for operational procedures like patching, health checks, or remediation.

Related: Runbook Execution, Task
Runbook Execution

A single instance of a runbook being run, tracking step status, output, approvals, and completion for audit and troubleshooting.

Related: Runbook, Approval Policy
Task

An individual unit of work within a runbook or lifecycle action, which may be an automated script, an API call, or a manual step awaiting human completion.

Related: Runbook, Lifecycle Action
X-Play

The Nutanix automation engine that supplies the action library behind Playbooks, offering reusable actions for VM operations, notifications, HTTP calls, and scripting.

Related: Playbook Action, Webhook, REST API
REST API

The HTTP-based programmatic interface of Prism Central, used to create, read, update, and delete resources and to integrate external tools with Nutanix automation.

Related: API Version, Webhook, Prism Central
Webhook

An outbound HTTP callback that automation sends to an external endpoint, carrying event or execution data so third-party systems can react in near real time.

Related: X-Play, REST API
API Version

The versioned path segment, such as v3 or v4, in Prism Central REST endpoints that determines request and response schemas and must match the client's expectations.

Related: REST API
ncli

A command-line interface for managing Nutanix clusters, used to inspect and configure storage, networking, and cluster settings from a shell session.

Related: Prism Element, acli
acli

The Acropolis command-line interface used to manage VMs and images on a cluster, including power operations, cloning, and listing VM inventory.

Related: ncli, Prism Element
Alert

A notification generated by Prism Central when a monitored condition crosses a threshold or a fault is detected, often used as a trigger for automated remediation.

Related: Alert Trigger, Playbook
Policy

A governance rule in Prism Central that enforces configuration or protection requirements across scoped resources, such as protection domain assignment or category compliance.

Related: Categories, Role-Based Access Control
Role-Based Access Control

The permission model that grants users roles scoped to projects or categories, determining which actions and resources they can access in Prism Central and Calm.

Related: Project, Policy
Audit Log

A chronological record of user and system actions in Prism Central, used to trace who changed what and to investigate automation failures.

Related: Runbook Execution, Alert
Registered Cluster

A Prism Element cluster that has been added to Prism Central, making its VMs, hosts, and storage visible and manageable from the central console.

Related: Prism Central, Prism Element
Environment

A Calm construct representing a target deployment context, such as development or production, that binds blueprints to specific clusters, networks, and credentials.

Related: Blueprint, Project
Credential

A stored username and secret used by automation actions and scripts to authenticate to endpoints, VMs, or external systems without hardcoding secrets in scripts.

Related: Playbook Action, REST API
Endpoint

A configured connection target, such as a REST URL or SSH host, that automation actions use to reach external systems or guest operating systems.

Related: Credential, Webhook
Manual Approval Step

A runbook or Playbook step that halts execution until a human reviewer explicitly approves or rejects it, providing a control point for risky operations.
