It is possible to increase/decrease the log files count, however increasing the files will have an impact on the performance of the application. Also it is not recommended to increase the count more than 30.
The serverout count can be decreased in the logs.
Kindly navigate to the file "logging.properties" under \ManageEngine\ServiceDeskPlus-MSP\conf, where you can change the file count value
com.adventnet.mfw.logging.AsyncExtendedJDKFileHandler.level = ALL
com.adventnet.mfw.logging.AsyncExtendedJDKFileHandler.formatter = com.adventnet.mfw.logging.DefaultFormatter
com.adventnet.mfw.logging.AsyncExtendedJDKFileHandler.limit = 10000000
com.adventnet.mfw.logging.AsyncExtendedJDKFileHandler.count = 10
com.adventnet.mfw.logging.AsyncExtendedJDKFileHandler.pattern = ../logs/serverout%g.txt
com.adventnet.mfw.logging.AsyncExtendedJDKFileHandler.append = true
Change the value to 10 in the highlighted line.
Shut down and start the application once.
