Hello!

I have to set a sincedb\_path file for logstash.

However, I have to create one and I cannot find the file type required. What should it be? (CSV, TXT, JSON...)

Thank you 🙂

No need to create it, Logstash will create it  
Just set the path to where you wish to persist it  
Every time logstash input process a file, it will update the sincedb file to keep tracking processed files

The problem is, I just set a path... and logstash logs tell me that:

"The "sincedb\_path" argument must point to a file, received a directory"

Yes, the path is the absolute path to the file name, example `/opt/sincedb/file_tracking.txt`  
Then it's logstash that will create the file `file_tracking.txt`
