Monitoring Aurora PostgreSQL Limitless Database with Amazon CloudWatch Logs - Amazon Aurora

Monitoring Aurora PostgreSQL Limitless Database with Amazon CloudWatch Logs

Exporting PostgreSQL logs to CloudWatch Logs is required as part of enabling Aurora PostgreSQL Limitless Database. You can access and analyze these logs in CloudWatch Logs Insights, similar to accessing PostgreSQL logs for a standard Aurora PostgreSQL DB cluster. For more information, see Analyzing PostgreSQL logs using CloudWatch Logs Insights.

The log group name for the DB cluster is the same as in Aurora PostgreSQL:

/aws/rds/cluster/DB_cluster_ID/postgresql

The log group name for the DB shard group takes the following form:

/aws/rds/cluster/DB_cluster_ID/DB_shard_group_ID/postgresql

There are log streams for each node (router or shard). Their names have the following form:

[DistributedTransactionRouter|DataAccessShard]/node_cluster_serial_ID-node_instance_serial_ID/n

For example:

  • Router – DistributedTransactionRouter/6-6.2

  • Shard – DataAccessShard/22-22.0

Note

You can't view PostgreSQL log files for the DB shard group directly in the RDS console, AWS CLI, or RDS API as you can for the DB cluster. You must use CloudWatch Logs Insights to view them.
