      from azure.identity import DefaultAzureCredential
from azure.mgmt.monitor import MonitorManagementClient
from azure.mgmt.monitor.models import AlertRuleResource

# Authenticate using the default credentials
credential = DefaultAzureCredential()

# Create a MonitorManagementClient
monitor_client = MonitorManagementClient(credential, subscription_id)

# Define the alert rule properties
alert_rule = AlertRuleResource(
    location='global',
    description='High CPU usage alert',
    severity='3',
    enabled=True,
    condition={
        'odata.type': 'Microsoft.Azure.Management.Monitor.Models.ThresholdRuleCondition',
        'dataSource': {
            'odata.type': 'Microsoft.Azure.Management.Monitor.Models.RuleMetricDataSource',
            'resourceUri': '/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Web/sites/{webAppName}',
            'metricName': 'CpuPercentage',
            'operator': 'GreaterThan',
            'threshold': 80,
            'timeAggregation': 'Average',
            'windowSize': 'PT5M'
        }
    },
    actions=[
        {
            'odata.type': 'Microsoft.Azure.Management.Monitor.Models.RuleEmailAction',
            'sendToServiceOwners': True
        }
    ]
)

# Create the alert rule
monitor_client.alert_rules.create_or_update(
    resource_group_name='your-resource-group',
    rule_name='high-cpu-alert',
    parameters=alert_rule
)

  2. Security and Compliance:
