Terraform AZURE MONITOR ALERTS

Terraform module to create monitor alerts resource on AZURE.

---

We eat, drink, sleep and most importantly love DevOps. We are working towards strategies for standardizing architecture while ensuring security for the infrastructure. We are strong believer of the philosophy Bigger problems are always solved by breaking them into smaller manageable problems. Resonating with microservices architecture, it is considered best-practice to run database, cluster, storage in smaller connected yet manageable pieces within the infrastructure.

This module is basically combination of Terraform open source and includes automatation tests and examples. It also helps to create and improve your infrastructure with minimalistic code instead of maintaining the whole infrastructure code yourself.

We have fifty plus terraform modules. A few of them are comepleted and are available for open source usage while a few others are in progress.

Prerequisites

This module has a few dependencies:

• Terraform 1.x.x
• Go
• github.com/stretchr/testify/assert
• github.com/gruntwork-io/terratest/modules/terraform

Examples

IMPORTANT: Since the master branch used in source varies based on new modifications, we suggest that you use the release versions here.

Here are some examples of how you can use this module in your inventory structure:

action group

  module "monitor-alerts" {
  source                         = "clouddrove/monitor-alerts/azure"
  version                        = "1.0.0"
  name                           = "app"
  environment                    = "test"
  label_order                    = ["name", "environment"]

  actionGroups = {
    "group1" = {
      actionGroupName      = "AlertEscalationGroup"
      actionGroupShortName = "alertesc"
      actionGroupRGName    = module.resource_group.resource_group_name
      actionGroupEnabled   = "true"
      actionGroupEmailReceiver = [
        {
          name                    = "example"
          email_address           = "example@gmail.com"
          use_common_alert_schema = "true"
        },
        {
          name                    = "test"
          email_address           = "test@gmail.com"
          use_common_alert_schema = "true"
        }
      ]
    }
  }
}

Testing

In this module testing is performed with terratest and it creates a small piece of infrastructure, matches the output like ARN, ID and Tags name etc and destroy infrastructure in your AWS account. This testing is written in GO, so you need a GO environment in your system.

You need to run the following command in the testing folder:

  go test -run Test
