1. API Health Monitoring for AI Services with Checkly


    Monitoring the health of your API endpoints is crucial, especially when these endpoints serve AI services that might be computationally intensive or require high availability. Checkly is a service that allows you to monitor the performance and correctness of API endpoints, among other things.

    In the context of using Pulumi, which is an Infrastructure as Code (IaC) tool, we can programmatically define the monitoring resources that Checkly provides. These resources can be integrated into your existing Pulumi infrastructure codebase, allowing you to manage and version control your monitoring setup alongside your service definitions.

    Below is a Pulumi Python program that defines a simple Checkly check for an API endpoint. This check will monitor the endpoint and trigger an alert if it fails based on criteria you define.

    Here's what we are doing in the Pulumi code:

    1. Importing the Pulumi Checkly package: This is necessary to use the resources provided by the Checkly provider during Pulumi deployments.
    2. Creating a Checkly Check: This resource represents a check that will be performed by Checkly. You would replace the example URL and other configuration values with the specific details relevant to the API endpoint you want to monitor.
    3. Setting assertions: These are conditions that the API must meet for the check to pass. An example assertion is included to check for a 200 OK HTTP response status code.
    4. Defining alert settings: These settings configure the conditions under which you want to be notified about check failures.
    5. Exporting the check URL: This will output the Checkly Dashboard URL to access the monitor status after deployment.

    Now, let's translate this into the Pulumi code.

    import pulumi import pulumi_checkly as checkly # Create a Checkly API Check for an imaginary AI Service. api_check = checkly.Check("ai-service-status-check", # Your API endpoint you wish to monitor. request = checkly.CheckRequestArgs( url = "https://api.your-ai-service.com/health", method = "GET", ), # Assertions define what a successful check should look like. assertions = [ checkly.CheckAssertionArgs( source = "STATUS_CODE", comparison = "EQUALS", target = "200", # Expecting a 200 OK response. ), ], # Frequency of checks in minutes. frequency = 1, # List of regions from where the checks will be performed. locations = ["us-west-1"], # Type of the check, could also be "BROWSER" if monitoring a website. type = "API", # Alert settings define when notifications should be sent. alert_settings = checkly.CheckAlertSettingsArgs( escalation_type = "RUN_BASED", run_based_escalations = [ checkly.CheckAlertSettingsRunBasedEscalationArgs(failed_run_threshold = 1), ], ), # Activate the check immediately after deployment. activated = True, ) # Export the check ID. pulumi.export("check_id", api_check.id)

    Now you have a Pulumi program that defines a Checkly check to monitor the health of your AI service's API endpoint. Once you run this program with Pulumi, it will set up the specified check on Checkly and monitor your endpoint according to the parameters you've set. If the endpoint fails to meet your criteria (in this case, returning a status code other than 200), Checkly will escalate according to your alert settings.

    This is a simple starting point, and the Checkly provider for Pulumi offers many more configurations to tailor the monitoring to your needs. You could add more complex assertions, configure the checks to run from more locations worldwide, or even set up maintenance windows during which failing checks are expected and should not alert.

    To learn more about the specific settings and options you can use with the Checkly provider, check out the Checkly provider documentation on Pulumi:

    Before using this program, make sure to install the Pulumi Checkly provider plugin by running pulumi plugin install resource checkly v1.1.4. And also, make sure that you have the Checkly SDK installed in your environment, which you can do with pip install pulumi_checkly.
