Your organization requires that metrics from all applications be retained for 5 years for future analysis in possible legal proceedings. Which approach should you use?

The correct approach is to configure Stackdriver Monitoring (now Google Cloud Monitoring) for all projects and export the metrics to Google Cloud Storage. Google Cloud Monitoring's default retention for metrics is typically 24 months, which is insufficient for the 5-year requirement. Exporting to Google Cloud Storage allows for long-term, cost-effective storage of metrics data, which can then be analyzed as needed. Granting the security team access to logs in each project addresses access but not the long-term retention of metrics. Exporting to BigQuery is suitable for analytical queries over large datasets, but for raw, long-term archival storage of metrics for potential legal proceedings, Cloud Storage is generally more appropriate and cost-effective.
