Automated Alert Triage for AI Systems on Azure

Question

Pulumi · Accepted Answer

Automated Alert Triage is an essential aspect of cloud operations, especially when dealing with AI systems where prompt responses to incidents can be necessary to maintain system integrity and performance. On Azure, this can be accomplished by setting up smart detection rules and alert processing mechanisms that automatically react to specific conditions in your environment.

In this program, we will use Pulumi with the `azure-native` provider to set up a Smart Detector Alert Rule. This Alert Rule will monitor our AI system's resources and send notifications or trigger actions based on defined anomalies or performance metrics.

We'll accomplish this by doing the following:

1. Establishing a monitoring scope over the resources we wish to watch.
2. Creating a Smart Detector Alert Rule to specify the logic for the alerts.
3. Defining the action groups that will respond to the alerts (e.g., sending emails, calling webhooks, etc.).

Below is a Pulumi program written in Python which steps through the process of setting up an automated alert triage system on Azure:

```python
import pulumi
import pulumi_azure_native.alertsmanagement as alertsmanagement
import pulumi_azure_native.insights as insights

# Configure the necessary Azure provider settings, such as location and resource group name.
resource_group_name = 'my-resource-group'
location = 'East US'

# Set up an Azure resource group, which is a container that holds related resources for an Azure solution.
resource_group = insights.ResourceGroup('resourceGroup',
                                       resource_group_name=resource_group_name,
                                       location=location)

# Define the Action Group, where the email receiver is set up to receive alerts.
action_group_name = 'my-action-group'
action_group_email_receiver_name = 'my-email-receiver'
action_group = alertsmanagement.ActionGroup(
    'actionGroup',
    action_group_name=action_group_name,
    resource_group_name=resource_group_name,
    location='Global',
    group_short_name=action_group_name.lower(),
    enabled=True,
    email_receivers=[
        {
            "name": action_group_email_receiver_name,
            "email_address": "alert@example.com",  # Replace with a real email address.
            "use_common_alert_schema": True
        }
    ])

# Create a Smart Detector Alert Rule that monitors all resources in the specified resource group.
smart_detector_alert_rule_name = 'my-smart-detector-rule'
smart_detector_alert_rule = alertsmanagement.SmartDetectorAlertRule(
    'smartDetectorAlertRule',
    alert_rule_name=smart_detector_alert_rule_name,
    resource_group_name=resource_group_name,
    location=location,
    severity=alertsmanagement.Severity.FOUR,  # Set the severity of the rule.
    detector=alertsmanagement.DetectorArgs(
        id='detector-id',  # Provide the correct detector ID for the AI monitoring that you're using.
        parameters={}
    ),
    scope=[resource_group.id],
    action_groups=alertsmanagement.ActionGroupArgs(
        group_ids=[action_group.id],
        custom_webhook_payload='{}'
    ),
    frequency='PT5M',  # Sets the frequency of evaluation for the rule. Example: Every 5 minutes.
    state='Enabled'
)

# Export the IDs of the created resources to view them in the Azure portal or another tool.
pulumi.export('action_group_id', action_group.id)
pulumi.export('smart_detector_alert_rule_id', smart_detector_alert_rule.id)
```

This Pulumi program uses `azure-native` resources to monitor your Azure services with smart detector alert rules:

- `ResourceGroup`: This is a logical container for our Azure resources where the monitoring will occur.
- `ActionGroup`: The action group specifies what action should be taken when an alert is triggered. In our program, it's configured to send an email.
- `SmartDetectorAlertRule`: The rule itself that specifies the detector logic. This rule will check the defined scope at the set frequency and, upon detecting an issue, will use the action group to notify the necessary parties.

When you run this program with Pulumi, it will provision these resources in your Azure account, and you'll have an automated alerting system watching over your AI system's health. You can modify the detector logic and actions to fit your specific use case.
