title: Autorun script for any activity on linux server
body: <p>so i have around 500 servers for which i wanted to create a script that automatically login and do some trivial activity to create some logs (basically want to send logs through siem tool to check if log sending is working or not) and then automatically logoff from the server. 
  I am planning that the script can be auto-run on the server every 15 days.
  trivial activity can be anything(just want to create logs). 
  Any help how to achieve that??</p>
  
  <p>EDIT</p>
  
  <p>i was thinking now that stopping and starting a service in server will accomplish my need. Any help on that script. i am actually new in working in linux server. so any help is greatly appriciated.</p>
