Google alert policy triggers issues based on cloud storage bucket object count

Question

I have been trying to setup alert policies(thru stack-driver) to get email notifications whenever there is new object in the cloud storage bucket.

But the issue here is, it works sometimes after a while and most of the other times, it wont.

How do we make the alerts triggered immediately as in when there is a new file in the bucket(multiple times per day).

Below is the code:

resource "google_monitoring_alert_policy" "alert_policy" {
  display_name = "File notification"
  combiner     = "OR"
  notification_channels = ["${google_monitoring_notification_channel.email.name}"]

  conditions {
    display_name = "File Notification"

    condition_threshold {
      comparison        = "COMPARISON_LT"
      duration          = "60s" 
      filter            = "metric.type=\"storage.googleapis.com/storage/object_count\" resource.type=\"gcs_bucket\" resource.label.\"bucket_name\"=\"realbucketname\""
      threshold_value   = 1

      aggregations {
        alignment_period        = "60s"
        per_series_aligner      = "ALIGN_COUNT"
      }

      trigger {
        count = 1
      }
    }
  }
  documentation {
    content = "There is a new file"
  }
}

Appreciate your inputs!

Thank you

Thank you. I had it fixed by removing aggregations in my scripts,

It worked as expected now !!!

    condition_threshold {   
      comparison        = "COMPARISON_GT"
      duration          = "60s" 
      filter            = "metric.type=\"storage.googleapis.com/storage/object_count\" resource.type=\"gcs_bucket\" resource.label.\"bucket_name\"=\"realbucketname\""
      threshold_value   = 1
