  2. Deploy a GCP Monitoring Alert Policy with Pulumi

How do I deploy a GCP monitoring alert policy with Pulumi?

In this guide, we will demonstrate how to deploy a Google Cloud Platform (GCP) monitoring alert policy using Pulumi. This alert policy will help you monitor your GCP resources and notify you when certain conditions are met. We will define the alert policy with conditions and notification channels.

Below is the Pulumi program written in TypeScript:

import * as pulumi from "@pulumi/pulumi";
import * as gcp from "@pulumi/gcp";

// Define a notification channel
const notificationChannel = new gcp.monitoring.NotificationChannel("exampleNotificationChannel", {
    displayName: "Example Notification Channel",
    type: "email",
    labels: {
        email_address: "example@example.com",
    },
});

// Define an alert policy
const alertPolicy = new gcp.monitoring.AlertPolicy("exampleAlertPolicy", {
    displayName: "Example Alert Policy",
    conditions: [{
        displayName: "Example Condition",
        conditionThreshold: {
            filter: "metric.type=\"compute.googleapis.com/instance/cpu/utilization\" AND resource.type=\"gce_instance\"",
            comparison: "COMPARISON_GT",
            thresholdValue: 0.8,
            duration: "60s",
            aggregations: [{
                alignmentPeriod: "60s",
                perSeriesAligner: "ALIGN_MEAN",
            }],
        },
    }],
    combiner: "OR",
    notificationChannels: [notificationChannel.id],
    enabled: true,
    documentation: {
        content: "This alert policy monitors the CPU utilization of GCE instances and triggers an alert if it exceeds 80% for 60 seconds.",
    },
});

Key Points:

  • We define a notification channel that sends email notifications.
  • We create an alert policy that monitors the CPU utilization of GCE instances.
  • The alert policy triggers when the CPU utilization exceeds 80% for 60 seconds.
  • The alert policy is linked to the notification channel to send alerts.

Summary:

In this guide, we demonstrated how to deploy a GCP monitoring alert policy using Pulumi. We defined a notification channel and an alert policy with specific conditions to monitor the CPU utilization of GCE instances. This setup helps ensure that you are notified when the specified conditions are met, allowing you to take necessary actions promptly.
