The Information Schema FEEDBACK table is created when the Feedback Plugin is enabled, and contains the complete contents submitted by the plugin.

It contains two columns:

ColumnDescription
VARIABLE_NAMEName of the item of information being collected.
VARIABLE_VALUEContents of the item of information being collected.

It is possible to disable automatic collection, by setting the feedback_url variable to an empty string, and to submit the contents manually, as follows:

$ mysql -e 'select * from information_schema.feedback' > report.txt

Then you can send it by opening https://mariadb.org/feedback_plugin/post in your browser, and uploading your generated report.txt. Or you can do it from the command line with (for example):

$ curl -F data=@report.txt https://mariadb.org/feedback_plugin/post

Manual uploading allows you to be absolutely sure that we receive only the data shown in the INFORMATION_SCHEMA.FEEDBACK table and that no private or sensitive information is being sent.

Example

SELECT * FROM INFORMATION_SCHEMA.FEEDBACK\G
