• aws_athena_cloudtrail_ddl.sql - AWS Athena DDL to setup up integration to query CloudTrail logs from Athena
• bigquery_billing_*.sql - Google BigQuery billing queries for GCP services eg. highest cost services, most used GCP products, recent charges etc.
• mysql_*.sql - MySQL / MariaDB queries for DBA investigating + performance tuning
  • tested on MySQL 5.5, 5.6, 5.7, 8.0 and MariaDB 5.5, 10.x
  • mysql_info.sql - summary overview, useful to debug your mysql.user table auth effects (intended USER() vs actual CURRENT_USER())
• postgres_*.sql - PostgreSQL queries for DBA investigating + performance tuning
  • tested on PostgreSQL 8.4, 9.x, 10.x, 11.x, 12.x
  • postgres_info.sql - big summary overview, recommend you start here

You can quickly test the PostgreSQL / MySQL scripts using postgres.sh / mysqld.sh / mariadb.sh in the DevOps Bash tools repo, which boots a docker container and drops in to mysql / psql shell with this directory mounted at /sql and used as $PWD for fast easy sourcing eg.

postgres:

\i /sql/postgres_query_times.sql

mysql:

source /sql/mysql_sessions.sql

or just

\i postgres_query_times.sql

\. mysql_sessions.sql

since the $PWD is set to /sql for convenience.
