Debug Output

Expected Behavior

When using exponential_buckets, floating point numbers should be supported for the attribute "growth_factor". At least in the Stackdriver UI I can enter a float.

Actual Behavior

Error: bucket_options.0.exponential_buckets.0.growth_factor: must be a whole number, got 1.414213562

  on ../slo-generator/logs-based-metrics.tf line 43, in resource "google_logging_metric" "latency_distribution":
  43: resource "google_logging_metric" "latency_distribution" {

Workarround :

Update manualy the value growth_factor using Stackdriver UI and add in the Terraform ressource block :

lifecycle {
    ignore_changes = [bucket_options]
  }
