Cloud Monitoring

BigQuery Data Transfer Service exports monitoring data to Cloud Monitoring.

You can use monitoring metrics for the following purposes:

  • Evaluate the usage and performance a data transfer configuration.
  • Troubleshoot problems.
  • Monitor transfer run statuses.

To create custom dashboards, set up alerts, and query metrics with Monitoring, you can use the Google Cloud console or the Monitoring API.

Viewing transfer data in Metrics Explorer

  1. In the Cloud console, go to the Monitoring page.

    Go to Monitoring.

  2. In the navigation pane, click Metrics Explorer.

Metric reporting frequency and retention

Metrics for BigQuery Data Transfer Service runs are exported to Monitoring in batches, at 1-minute intervals. Monitoring data is retained for 6 weeks.

The dashboard provides data analysis in default intervals of 1h (1 hour), 6H (6 hours), 1D (1 day), 1W (1 week), and 6W (6 weeks). You can manually request analysis in any interval between 1M (1 minute) to 6W (6 weeks).

Monitoring metrics for transfer configurations

The following metrics for BigQuery Data Transfer Service configs are exported to Monitoring:

Metric Description
Run latency distribution Distribution of the execution time (in seconds) of each transfer run, per transfer configuration.
Active run count Number of transfer runs that are running or pending, per transfer configuration.
Completed run count Number of completed transfer runs in a time period, per transfer configuration.

Filtering dimensions for metrics

Metrics are aggregated for each BigQuery Data Transfer Service configuration. You can filter aggregated metrics by the following dimensions:

Property Description

  • unspecified
  • pending
  • running
  • succeeded
  • failed

  • OK
  • CANCELLED
  • UNKNOWN
  • INVALID_ARGUMENT
  • DEADLINE_EXCEEDED
  • NOT_FOUND
  • ALREADY_EXISTS
  • PERMISSION_DENIED
  • UNAUTHENTICATED
