Hi,
In config.lua, in the logAppenders section, the fileHistorySize and fileLength settings can help minimize the number of files. For example, you can set fileHistorySize=2 to retain only the last 2 log files. You can also set fileLength to a very large value to fit a typical day’s worth of data, more or less.
For details, please refer to the EMS User Guide:
