Hi,

I have a local log file which is updated constantly. I have the following input filter in place:

file  
{  
path =\> ["/home/joseph/Desktop/audit.log"]  
start\_position =\> "beginning"  
sincedb\_path =\> "/dev/null"  
exclude =\> "\*.gz"  
}

However, since I set the start\_position to beginning, the entire file is read each time the file is updated. Is it possible for me to configure logstash to only ship the new logs ( by tailing) to Elasticsearch?

That is why 🙂

My bad!

Thank you!

I assume it should work if I remove that line. 🙂
