I am using this configuration for my logging system.

logging.config.dictConfig(
    {
        "version": 1,
        "disable_existing_loggers": False,
        "formatters": {
            "format": {"format": "%(asctime)s - %(name)s - %(levelname)s - %(message)s"}
        },
        "handlers": {
            "console": {
                "class": "logging.StreamHandler",
                "formatter": "format",
                "stream": "ext://sys.stdout",
            },
            "file": {
                "class": "logging.handlers.RotatingFileHandler",
                "filename": "data/logs/main.log",
                "mode": "a",
                "formatter": "format",
                "maxBytes": 1024 * 1024,
                "backupCount": 100,
            },
        },
        "root": {"handlers": ["console", "file"], "level": "DEBUG"},
    }
)

this configuration makes 11 log files for my project with these names:

• main.log
• main.log.1
• main.log.2

…

• main.log.99
• main.log.100

I want these names to be something like these:

• main.log
• main-00.log
• main-01.log

…

• main-98.log
• main-99.log

How can I do this customization on the name of log files?

Another problem is that main-36.log may have the newest logs and so main-37.log has the oldest logs.

I want when the size of main.log reaches the maxBytes all of the log files to shift one (

• main-01.log copy to main-00.log
• main-02.log copy to main-01.log

…

• main-98.log copy to main-97.log
• main-99.log copy to main-98.log

) and after that main.log copy on last file (main-99.log).

in this order, main-99.log always has the newest logs and main-00.log always has the oldest logs

How can I do these?
