Harvesting Data: Python's Gateway to Aria Operations Metrics

Unlock the power of Python to seamlessly gather and harness data from Aria Operations (vROps). This blog post introduces a Python script that connects to vROps, efficiently authenticating to obtain a secure token. This token is the golden key, allowing the script to pull detailed metrics for a virtual machine named 'Raspberry'.

import requests
import json

# Replace these with your vROps details
vrops_host = 'https://ariaops.ntpro.local'
username = 'admin'
password = 'VMware1!'

# Endpoints
auth_url = f'{vrops_host}/suite-api/api/auth/token/acquire'
vm_search_url = f'{vrops_host}/suite-api/api/resources'
metrics_url_template = f'{vrops_host}/suite-api/api/resources/{{}}/stats'

# Authenticate and Get Token
headers = {'Content-Type': 'application/json', 'Accept': 'application/json'}
payload = {'username': username, 'password': password}
response = requests.post(auth_url, headers=headers, data=json.dumps(payload), verify=False)
token = response.json().get('token')

if not token:
    raise Exception("Authentication failed")

# Update headers with the token
headers['Authorization'] = f'vRealizeOpsToken {token}'

# Function to get the ID of a VM by its name
def get_vm_id(vm_name):
    vm_url = f'{vrops_host}/suite-api/api/resources'
    response = requests.get(vm_url, headers=headers, verify=False)
    if response.status_code == 200:
        resources = response.json()['resourceList']
        for resource in resources:
            if resource['resourceKey']['name'] == vm_name:
                return resource['identifier']
    return None

# Function to get metrics for a VM by its ID
def get_vm_metrics(vm_id):
    metrics_url = f'{vrops_host}/suite-api/api/resources/{vm_id}/stats'
    response = requests.get(metrics_url, headers=headers, verify=False)
    if response.status_code == 200:
        return response.json()
    return None

# Main script execution
vm_id = get_vm_id('raspberry')
if vm_id:
    vm_metrics = get_vm_metrics(vm_id)
    if vm_metrics:
        print("Metrics for VM 'raspberry':")
        print(json.dumps(vm_metrics, indent=4))
    else:
        print("Failed to retrieve metrics for VM 'raspberry'")
else:
    print("VM 'raspberry' not found")

Through this script, you can effortlessly access the Aria Ops REST API, which is designed to safeguard and validate your data retrieval missions. Once authenticated, you can harvest a rich dataset, which can then be woven into your custom solutions or operational dashboards. By leveraging this script, raw data can be transformed into actionable insights, enhancing virtual machine monitoring and management.
