"Total Size of InnoDB Log Files" missing on "InnoDB Log File Usage Hourly" Graph

[gordan-bobic]

it looks like on recent MariaDB (10.5+), we don't get the "Total Size of InnoDB Log Files" red line on the "InnoDB Log File Usage Hourly" graph. I am not 100% sure, but I suspect it could be because in recent MariaDB there is only one InnoDB log file rather than multiple log files. That could be upsetting the calculation.

Please adjust the graph calculation so it works with both old (<= 10.4) and new (>= 10.5) versions.

You're probably right, the graph uses innodb_log_files_in_group * innodb_log_file_size to calculate the value, and the innodb_log_files_in_group global variable is ablout to be removed in 10.6, it's still there in 10.5.19, so the graph should work with (<= 10.5.19) I think, maybe they removed it in (>= 10.5.20)

Wait, it seems that 10.5.19 is the latest version of 10.5, and the graph is working, are you sure it's not 10.6 we are talking about?

10.7.x is definitely manifesting the problem, try with that.
