How many log files are kept on the Grid Member? [ Edited ]

[#1]

Hi;

When setting the logging settings at the member level, as can be seen from the attached screen-shot, how many log file are kept until purging of old files start. Is there a number of files or a limit in Bytes to how much log files can be kept all in all.

Or is it really the one log file, which is the current one and once the limit of query data is reached then a new file starts and the old one purged.

Kindly
