----------------------------------
Still want to know your opinions about this feature, listing the log files for
TaskManager on Flink web UI.
For the rolling logging strategy, it is very helpful. cc [~Zentol]

> Currently, there are some features to be enhanced when Flink web UI displays
> TaskManager logs:
> 1) Flink web UI can only display the log of task manager and stdout;
> 2) Flink web UI can only display the latest one log file;
> In the log folder of a Task Manager, we usually have more files, including GC
> log files, multiple files generated based on the rolling rules of the logging
> framework (time or log file size), user's business log files (We internally
> implemented the separation of Flink from the user log). For these files, the
> current Flink web UI cannot be displayed.
> I personally suggest that we can refer to the way YARN displays the
> container's log (see attachment 1), first list all the log files (see
> attachment 2), and then click to display the files of these logs.
>
> This feature can be independent or part of the log separation (see
> FLINK-11202).
> It has now been added to the design documentation for Log separation:
