Terraform Google provider, create log-based alerting policy

Question

I need to create a log-based alerting policy via Terraform Google cloud provider : https://cloud.google.com/logging/docs/alerting/monitoring-logs#lba

I checked from the Terraform official documentation and i saw 'google_monitoring_alert_policy' resource : https://registry.terraform.io/providers/hashicorp/google/latest/docs/resources/monitoring_alert_policy

I don't found with this doc how creating a log based alerting policy.
I can create an alerting policy with type 'Metrics' but not with type 'Logs'

I use the latest version of Terraform Google cloud provider : https://registry.terraform.io/providers/hashicorp/google/latest

How can i create a log-based alerting policy with Terraform Google provider please ?

Thanks in advance for your help.

Thanks Guillaume.

Yes it's the way i solved the issue.

Now there is no way to directly create alerting with log type, via Terraform.

The steps to solve this problem :

• Create un log based metric with expected filter
• Create an alerting policy with type metric based on the previous created log based metric

resource "google_logging_metric" "my_log_metrics" {
  project = var.project_id
  name = "my-log-metric"
  filter = "..."
  description = "..."
  metric_descriptor {
    metric_kind = "..."
    value_type = "..."
  }
}

resource "google_monitoring_alert_policy" "my_policy" {
  project = var.project_id
  display_name = "my-policy"
  combiner = "OR"
  conditions {
    display_name = "my-policy"
    condition_threshold {
      filter = "metric.type=\"logging.googleapis.com/user/my-log-metric\" AND resource.type=\"cloud_composer_environment\""
    ...
    }
}
