Can't parse and index any more logs

Hi! I've come to the point where logstash and elasticsearch can't index anymore logs. It still has the logs from yesterday but apparently it can't capture anymore events. Is there someone who knows a solution to this? My guess is that I somehow need to empty my index of all the events and logs to be able to move on. Correct me if I'm wrong. I've been stuck on this for a few hours now.

Best regards!
