Overview of Automation and Scripting Capabilities

• RESTful APIs (v3/v4): Full-featured API access for all configuration, monitoring, and lifecycle tasks.
• SDKs: Python and PowerShell SDKs simplify development and integration.
• X-Play: Event-driven automation to trigger actions based on alerts, thresholds, or schedule.
• Calm: Application and infrastructure orchestration with blueprints, approvals, and governance.
• Runbooks: Automated workflows for routine IT operations.
• Integration: Seamless connections to external platforms like ServiceNow, Splunk, and Ansible.

Getting Started: Authentication and API Access

Generating an API Key

Before you can automate, you need credentials.

1. Log into Prism Central as an admin.
2. Go to Admin > API Keys.
3. Click Create API Key, name it, and download/save the key securely.

Note: API keys are safer than basic credentials for scripting and integrations.

Python Example: Authenticating and Listing VMs

import requests

# Replace with your Prism Central FQDN/IP and API key
PC_HOST = "https://prismcentral.example.com:9440"
API_KEY = "your_api_key_here"

headers = {
    "Content-Type": "application/json",
    "Accept": "application/json",
    "Authorization": f"ApiKey {API_KEY}"
}

url = f"{PC_HOST}/api/nutanix/v3/vms/list"

response = requests.post(url, headers=headers, json={})
vms = response.json().get('entities', [])
for vm in vms:
    print(f"VM Name: {vm['status']['name']}, UUID: {vm['metadata']['uuid']}")

---

PowerShell Example: Authenticating and Listing Clusters

# Install-Module Nutanix.Prism (if not already)
Import-Module Nutanix.Prism

$pcHost = "prismcentral.example.com"
$apiKey = "your_api_key_here"

Connect-NutanixPC -Server $pcHost -ApiKey $apiKey
Get-NTNXCluster | Format-Table Name, UUID, ClusterExternalIpAddress

Building Operational Automation

X-Play: Event-Driven Automation

• Use Case: Automatically add CPU to a VM if an alert triggers for CPU saturation.
• How: In Prism Central, go to Operations > X-Play.
  1. Create a new X-Play book.
  2. Set a trigger (e.g., alert: “VM CPU Usage High”).
  3. Add action: “Increase VM CPU.”
  4. Test and enable the playbook.

X-Play supports many built-in actions, plus you can call external webhooks or run scripts.

---

Calm Blueprints: Application and Infrastructure Orchestration

• Example: Deploy a 3-tier app across Nutanix clusters.
• How:
  1. Go to Calm > Blueprints > Create.
  2. Define app components, deployment sequence, dependencies, and policies.
  3. Add approval flows, versioning, and self-service catalog entries.
  4. Launch deployment directly or via API.

Calm blueprints can be launched on-demand, scheduled, or called by external CI/CD tools (Jenkins, Ansible).

---

Runbooks: Automate Day-to-Day Operations

• Use Case: Scheduled backup, health checks, nightly VM reports.
• How:
  1. In Prism Central, select Runbooks > Create.
  2. Define a sequence of tasks (e.g., snapshot VMs, run script, send Slack notification).
  3. Set triggers: manual, scheduled, or event-driven.
  4. Review, test, and enable.

Runbooks can call REST APIs, execute CLI commands, or integrate with external systems.

External Integration Examples

With Ansible

- name: Create a VM on Nutanix
  hosts: localhost
  collections:
    - nutanix.ncp
  tasks:
    - name: Create VM
      nutanix.ncp.vm:
        prism_host: "{{ prism_host }}"
        prism_user: "{{ prism_user }}"
        prism_password: "{{ prism_password }}"
        validate_certs: false
        state: present
        name: "new-ansible-vm"
        num_vcpus: 2
        num_cores_per_vcpu: 1
        memory_mb: 4096

With ServiceNow or Splunk

• Use Prism Central’s webhook/X-Play integrations to send alerts or operational events directly into ServiceNow (for ticketing) or Splunk (for analytics).
• You can automate incident creation, push audit logs, or ingest real-time telemetry.

---

Real-Time Operations: Monitoring and Alerting

Native Prism Dashboards

• Custom Dashboards:
  Create widgets and charts for cluster health, storage trends, VM performance, and alert states.
• Alert Policies:
  Define threshold-based or event-based alerts, customize notification channels (email, webhook, etc.).
• Historical Analysis:
  Use Prism Central’s capacity trend views, heatmaps, and anomaly detection for predictive ops.

---

Proactive Ops with X-Play and Runbooks

• Set up automated remediation: E.g., auto-migrate VMs if a host is degraded, snapshot and alert if suspicious activity is detected.
• Use real-time notifications to Slack, Microsoft Teams, or other chat tools for ops visibility.

---

Putting It All Together: Sample Workflow

Scenario:
A new project needs VMs provisioned, tagged, monitored, and managed via external ticketing.

Solution:

• Use Calm blueprint for VM provisioning with pre-built configurations.
• Automate tagging and monitoring via Python script or Ansible.
• Trigger ServiceNow ticket creation for tracking.
• Use X-Play to monitor VMs and auto-remediate performance issues.
• Dashboards track project VMs in real time, alerts feed to Splunk for centralized logging.

---

Best Practices

• Secure your API keys: Rotate regularly, never hard-code in scripts.
• Version control: Store scripts and blueprints in Git.
• Start with read-only scripts: Validate API results before making changes.
• Use test/dev clusters: Never run new automation in production first.
• Monitor outcomes: Integrate alerting into your automation workflows.
