In yaml check the Property filePattern defined as "${date:yyyy-MM-dd}", which helps to tag the date. If you are interested to tag the HOSTNAME environment variable to date then : "${env:HOST}-${date:yyyy-MM-dd}"

Properties:
    Property:
      - name: log-path
        value: "logs"
      - name:  filePattern
        value: "${date:yyyy-MM-dd}"

  Appenders:

    Console:
      name: Console_Appender
      target: SYSTEM_OUT
      PatternLayout:
        pattern: "[%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n"

    File:
      name: File_Appender
      fileName: "${log-path}/filelog-${filePattern}.log"

      PatternLayout:
        pattern: "[%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n"

    RollingFile:
      - name: RollingFile_Appender
        fileName: "${log-path}/rollingfile-${filePattern}.log"
        filePattern: "logs/archive/rollingfile.log.%d{yyyy-MM-dd-hh-mm}.gz"
        PatternLayout:
          pattern: "[%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n"
