Example for Azure Alert create using Python SDK

I am trying to create Azure Alert using Python SDK and Below is the code

from azure.mgmt.monitor import MonitorManagementClient
from azure.mgmt.monitor.models import RuleMetricDataSource
from azure.identity import DefaultAzureCredential
from azure.mgmt.monitor.models import ThresholdRuleCondition
from azure.mgmt.monitor.models import RuleEmailAction


subscription_id = 'xxxxxx-xxxxxxxxxx-xxxxxxxxx'
resource_group_name = 'example-rg'
vm_name = 'example_vm'

# Set up the credentials
credentials = DefaultAzureCredential()


resource_id = (
    "subscriptions/{}/"
    "resourceGroups/{}/"
    "providers/Microsoft.Compute/virtualMachines/{}"
).format(subscription_id, resource_group_name, vm_name)

# create client
client = MonitorManagementClient(
    credentials,
    subscription_id
)

# I need a subclass of "RuleDataSource"
data_source = RuleMetricDataSource(
    resource_uri=resource_id,
    metric_name='Percentage CPU'
)


# I need a subclasses of "RuleCondition"
rule_condition = ThresholdRuleCondition(
    data_source=data_source,
    operator='GreaterThanOrEqual',
    threshold=90,
    window_size='PT5M',
    time_aggregation='Average'
)

# I need a subclass of "RuleAction"
rule_action = RuleEmailAction(
    send_to_service_owners=True,
    custom_emails=[
        'abc@gmail.com'
    ]
)

rule_name = 'MyPyTestAlertRule'
my_alert = client.alert_rules.create_or_update(
    resource_group_name,
    rule_name,
    {
        'location': 'North Central US',
        'alert_rule_resource_name': rule_name,
        'description': 'Testing Alert rule creation',
        'is_enabled': True,
        'condition': rule_condition,
        'actions': [
            rule_action
        ]
    }
)

Unfortunately I am getting below error, difficult find any valid example code in the website. It would be really great if somebody provides a example to create Azure alert using python SDK.

As per error it classic alert rules based on this metric is no longer supported.

Traceback (most recent call last):

This worked for me.

I have used azure.mgmt.monitor from package azure-mgmt-monitor

For Reference check this document.

My Code:

app.py:

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


credentials = DefaultAzureCredential()
sub_id= "xxxxxxxxxxxxxxxxxxxxxxxxxxx"
resource_group = "xxxxxxxxxxxxxxxxx"
client = MonitorManagementClient(credential=credentials,subscription_id=sub_id)


Alert = client.metric_alerts.create_or_update(resource_group,
        "Metric_alert_",
        {
          "location": "global",
          "description": "This is the description of the rule1",
          "severity": "3",
          "enabled": True,
          "scopes": [
            f"/subscriptions/{sub_id}/resourceGroups/{resource_group}/providers/Microsoft.Compute/virtualMachines/testvm"
          ],

            "odata.type": "Microsoft.Azure.Monitor.MultipleResourceMultipleMetricCriteria",

                "metric_name": "Percentage CPU",
                "metric_namespace": "microsoft.compute/virtualmachines",
                "operator": "GreaterOrLessThan",
                "time_aggregation": "Average",
                "dimensions": [],
                "alert_sensitivity": "Medium",
                "failing_periods": {
                  "number_of_evaluation_periods": "4",
                  "min_failing_periods_to_alert": "4"
                },
              }
            ]
          },
          "auto_mitigate": False,
          "actions": [
          ]
        }
    )

print("Alert created Successfully.")
