1. Performance Threshold Alerts for Distributed AI Applications

    Python

    To set up performance threshold alerts for distributed AI applications, we must monitor various metrics such as response times, error rates, and resource usage across the infrastructure and applications. When any of these metrics cross predefined thresholds, an alert should be triggered. To accomplish this, you can leverage monitoring and alerting services provided by cloud platforms.

    For this explanation, we'll use New Relic as an example to configure an alert policy that will apply to a distributed AI application. New Relic is a popular observability platform that offers application performance monitoring (APM) and can send alerts when performance issues are detected.

    You will need to set up the following using Pulumi:

    1. Alert Policy: A grouping construct for a set of alert conditions, which defines a workflow for incident detection, notification, and remediation.

    2. Application Settings: To configure the APM settings for the distributed AI application, including setting up Apdex thresholds which are used to measure user satisfaction with the response time of your web applications. If response times exceed the thresholds, an alert can be triggered.

    3. NRQL Alert Conditions: These are alert conditions written using New Relic Query Language (NRQL). You can create a condition that queries specific performance metrics, and if the result of the query violates the threshold condition, an alert is sent out.

    4. Notification Channel: A destination for notifications when an incident is created, acknowledged, or resolved. You could set up emails, webhooks, or integration with other incident management services.

    In the example program below, we will create an alert policy and an NRQL condition that triggers an alert if the average response time of the AI application over the last 5 minutes exceeds a certain threshold. We'll also set up a notification channel for email alerts.

    import pulumi import pulumi_newrelic as newrelic # Create a new alert policy for our AI application ai_alert_policy = newrelic.AlertPolicy("aiAlertPolicy", name="AI Application Alert Policy", ) # Configure Apdex performance thresholds for the application ai_app_settings = newrelic.ApplicationSettings("aiAppSettings", name="AI Application", app_apdex_threshold=0.5, # Represents a tolerable threshold for response time (in seconds) end_user_apdex_threshold=0.7, enable_real_user_monitoring=True, ) # Create an NRQL alert condition for the alert policy # This condition will trigger an alert if the average response time is greater than 500 ms in the last 5 minutes nrql_alert_condition = newrelic.NrqlAlertCondition("highResponseTime", policy_id=ai_alert_policy.id, name="High Response Time", runbook_url="http://example.com/runbook", # A URL to a runbook with remediation steps enabled=True, value_function="single_value", nrql=newrelic.NrqlAlertConditionNrqlArgs( query="SELECT average(duration) FROM Transaction WHERE appName = 'AI Application'", evaluation_offset=3, ), critical=newrelic.NrqlAlertConditionCriticalArgs( operator="above", threshold=0.5, # Threshold set for 500 ms threshold_duration=300, # Duration set for 5 minutes threshold_occurrences="at_least_once", ), ) # Setup an email notification channel to send alerts email_channel = newrelic.NotificationChannel("emailChannel", name="AI Alert Email Notification", type="email", config=newrelic.NotificationChannelConfigArgs( recipients="ops-team@example.com", include_json_attachment="true", ), ) # Attach the email channel to the alert policy email_policy_channel = newrelic.AlertPolicyChannel("emailPolicyChannel", policy_id=ai_alert_policy.id, channel_id=email_channel.id, ) # Export the alert policy ID pulumi.export("ai_alert_policy_id", ai_alert_policy.id)

    In this Pulumi program, the newrelic.AlertPolicy class is used to create an alert policy which acts as a container for alert conditions. The newrelic.ApplicationSettings class is setting up the application's monitoring settings. An alert condition is created using the newrelic.NrqlAlertCondition class, which uses a NRQL query to monitor the application’s average response time and triggers an alert if it exceeds the threshold. Finally, the newrelic.NotificationChannel and newrelic.AlertPolicyChannel classes are used to set up a communication channel for receiving alerts.

    Note that to use New Relic with Pulumi, you will need to have the New Relic provider configured with the necessary credentials. Ensure you have the New Relic API keys set up in your environment or Pulumi configuration.

    This is just one example of setting up performance threshold alerts for distributed AI applications. Depending on your use case and the specific metrics you'd like to monitor, you would adjust the NRQL queries and alert conditions accordingly.
