The MySQL sys and ps_helper schemas contain a collection of views, functions and procedures that can be used by administrators to analyze and manage MySQL Servers and their activity.
Many of the objects are targeted against the performance_schema database within MySQL, and provide extra summary data around everyday DBA/Developer/operations use cases.
Both repositories are available on Github:
- MySQL sys schema – contains the most stable set of objects.
- dbahelper / ps_helper – contains experimental objects.
See the MySQL sys schema README file for examples and usage for all objects.
