hi,  
We are planning to implement ELK for aggregating the IIS logs from our web servers. However since this will also involve monitoring live logs, it would be good to know if the filebeat locks the IIS logs files while shipping the logs to ES/logstash?

Thanks.

Filebeat does not lock files. It opens the file for reading only. And it specifies that the file can be read, written, and deleted by other applications while it has it open.
