   • AUse a log sink to export debug logs to Cloud Storage and delete them from Cloud Logging.
   • BSet the log retention period to 30 days for all logs to reduce storage costs.
   • CCreate a log exclusion for debug logs and then create a log-based metric to count them.
   • DConfigure log sampling in the Ops Agent to sample debug logs at 10% and forward all other logs.
