Sincedb

This plugin creates a sincedb in your home, called .sincedb_journal. It automatically stores the cursor to the journal there, so when you restart logstash, only new messages are read. When executing the plugin the second time (which means the sincedb exists), seekto, and thisboot are ignored. If you don't want the sincedb, configure it's path to /dev/null. Tips

Ensure the user you are running logstash as has read access to the journal files /var/log/journal/*/*
