1. Proactive Anomaly Detection in AI Systems with Sentry Alerts


    To implement proactive anomaly detection in AI systems with Sentry alerts using Pulumi, we need to set up an anomaly detection service that can process data and identify anomalies. Then we should integrate it with Sentry to create alerts based on the anomalies detected. Oracle Cloud Infrastructure (OCI) has AI services for anomaly detection that we can use. We will define a model for detecting anomalies with OCI and set up a Sentry project for handling alerts.

    Firstly, we would create an AI Anomaly Detection Model in OCI. This requires a project to be associated with, as well as training details such as the dataset, the algorithm hints, etc. This model will be responsible for detecting anomalies based on the data we provide.

    Secondly, once we've got our anomaly detection model defined and trained, we will integrate alerts with Sentry. In Sentry, we have to create a project which will be configured to handle and notify if any anomaly is detected.

    Here is a Pulumi program written in Python that sets up both the OCI AI Anomaly Detection Model and a Sentry Project ready to receive alerts:

    import pulumi import pulumi_oci as oci import pulumi_sentry as sentry # Replace these variables with actual values. oci_compartment_id = "your-oci-compartment-id" oci_project_id = "your-oci-ai-project-id" sentry_organization = "your-sentry-organization-name" sentry_team_slug = "your-sentry-team-slug" # Define an OCI AI Anomaly Detection Model. ai_model = oci.aianomalydetection.Model("aiModel", compartment_id=oci_compartment_id, project_id=oci_project_id, display_name="AnomalyDetectionModel", description="Model to detect anomalies in AI systems", model_training_details=oci.aianomalydetection.ModelModelTrainingDetailsArgs( # The fraction of data to use for training; the rest is used for testing. training_fraction=0.7, # Target false alert probability. target_fap=0.05, # The number of buckets with data samples for model training. window_size=12, data_asset_ids=["data-asset-id"], # List of data asset IDs for training. algorithm_hint="FORECASTING" ), freeform_tags={ "environment": "production" } ) # Define a Sentry project for handling alerts. sentry_project = sentry.SentryProject("sentryProject", organization=sentry_organization, team=sentry_team_slug, name="AnomalyDetectionAlerts", platform="python" # Assuming Python for error tracking; change as needed. ) # Export the model ID and the Sentry project slug for further references. pulumi.export("model_id", ai_model.id) pulumi.export("sentry_project_slug", sentry_project.slug)

    This program does the following:

    • Imports the required Pulumi modules for OCI and Sentry.
    • Defines variables for compartment, project IDs, and Sentry organization details.
    • Creates an AI anomaly detection model resource (oci.aianomalydetection.Model) in OCI, specifying compartment and project IDs, display name, description, and model training details.
      • The model training details include specifications such as the training fraction (the portion of data used for training), the target false alert probability (target FAP), the window size, dataset IDs, and the algorithm hint.
      • freeform_tags are added to annotate our resource with metadata like the environment.
    • Sets up a Sentry project resource (sentry.SentryProject) where you can manage and track alerts and issues. It requires the name of your Sentry organization and the team slug.
    • Finally, it exports the model ID and Sentry project slug; these values can be used for setting up additional automation or for referencing the resources we've just created.

    This setup allows us to have a system that can detect anomalies and create alerts which will be handled by Sentry. When an anomaly is detected by the OCI model, we can then use the model ID to send the details to Sentry, triggering alerts as configured in the Sentry platform. Keep in mind that you will need to wire up the actual detection and alerting mechanism based on the model's output, typically through an event-driven architecture such as OCI Functions or OCI Events service.
