Logs files are overwritten every time rotation happens

[adityagoel19]

Here's my config:
rotateInterval │ 0 0 0 * * 0
dateFormat │ YYYY-MM-DD
max_size │ 50M

This should mean that logs should rotate every Sunday at midnight. However I think I am generating more logs than 50M every day. So log rotation happens every few hours. But I have just one log file generated per day which upon inspection does not contain entire day logs. I am losing logs here in PRODUCTION which is quite critical. Expected behavior is that log file name append something at the end like log__2019-09-05-1.log, log__2019-09-05-2.log if a log file named log__2019-09-05.log already exists.

I really think this should be documented better. By not having this what you really want the devs to do is that figure how much size of logs I am generating, and after that configure logrotate module in a way that no logs are lost.

Please help me if my understanding is wrong.
