DailyRotateFile Inquiries about options

[realtrynna]

Only up to 240 files should be maintained in the settings, but a total of 600 files are left because the 2022 files have not been deleted.

Why didn't the 2022 file get deleted?

Is there a way to check if each file was created by Winston?

const { createLogger, transports, format } = require("winston");
require("winston-daily-rotate-file");

const logDir = "./log/";
const logDirDate = "%DATE%";
const maxFileSize = "10M";
const maxFiles = 240;

const dailyRotateFileTransport = new transports.DailyRotateFile({
  level: "debug",
  filename: `${logDir}${logDirDate}.log`,
  datePattern: "YYMMDD.HH",
  maxSize: maxFileSize,
  maxFiles: maxFiles
});

const logger = createLogger({
  level: "debug",
  format: format.combine(
    format.timestamp({
      format: "YY-MM-DD HH:mm:ss"
    }),
    format.printf((info) => `[${info.timestamp}] ${info.level} ${info.message}`)
  ),
  transports: [
    new transports.Console({
      level: "info"
    }),
    dailyRotateFileTransport
  ]
});

module.exports = logger;
