Hi All

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 ??

Thanks

Assuming you're using the file input you can adjust the [`stat_interval`](https://www.elastic.co/guide/en/logstash/current/plugins-inputs-file.html#plugins-inputs-file-stat_interval) parameter to your liking. By default it polls the log files every second.

Oh, and you may want to change `discover_interval` too.
