How to create alerts for Azure resources using Terraform

I have prepared Terraform scripts for azure resources like App Service, AppService Plan, Storage Account and Logic App etc.….

I have deployed the above Terraform scripts successfully. But I want to configure the alerts for the above resources using Terraform.

Is there any way to create alerts by using Terraform without ARM Template deployment?

Sure there is. This is an example of a custom log search from Application Insights. But you can easily modify this for another source like Azure Monitor

resource "azurerm_application_insights" "example" {
  name                = "${var.prefix}-appinsights"
  location            = azurerm_resource_group.example.location
  resource_group_name = azurerm_resource_group.example.name
  application_type    = "web"
  retention_in_days   = 30
}

resource "azurerm_monitor_action_group" "example" {
  name                = "CriticalAlertsAction"
  resource_group_name = azurerm_resource_group.example.name
  short_name          = "p0action"

  email_receiver {
    name                    = "sendtoadmin"
    email_address           = "[email protected]"
    use_common_alert_schema = true
  }
}

resource "azurerm_monitor_scheduled_query_rules_alert" "example-alert1" {
  name                = "${var.prefix}-alertrule1"
  location            = azurerm_resource_group.example.location
  resource_group_name = azurerm_resource_group.example.name

  action {
    action_group = [
      azurerm_monitor_action_group.example.id
    ]
  }
  data_source_id = azurerm_application_insights.example.id
  description    = "Exception threshold reached"
  enabled        = true
  # Count all requests with server error result code grouped into 5-minute bins
  query       = <<-QUERY
  requests
    | where cloud_RoleName == "frontend" and name !contains "Health" and resultCode startswith "5" 
  QUERY
  severity    = 1
  frequency   = 5
  time_window = 5
  trigger {
    operator  = "GreaterThan"
    threshold = 10
  }
}
