We have a very old server that runs Java based web applications developed using ATG framework.
I need to do some monitoring on this server using the webserver logs (Apache) , the system administrators have come back asking me if there is an I/O cost involved by doing real-time pull of log entries.
Since this is a old server and runs some critical application they want to make sure Logstash pulling log entries doesn't cause any performance issues on the server.
From Logstash Can i do a pull of logs say every 10 minutes ??
