Aurora RDS Postgres DB alerts by query execution latency

Hello.

As you may know, RDS metrics do not include metrics related to slow queries.
So, enable query logging for RDS PostgreSQL and change "log_statement" to 1 in the RDS parameter group.
Also, by setting the value of "log_min_duration_statement" to 5000, queries that take more than 5 seconds to execute will be output to the log.
Please set the type of query you want to output to the log with the value of "log_statement".

After outputting to CloudWatch Logs, you can create metrics by using a metric filter, etc., and then you can create alarms.
