I have an index called "logstash-events" which holds a few million log entries that are sent from network devices across the network, but a majority of them(90.45%) are useless.
I filtered those out for the future, but I still have 90GB of used data which is very useless and makes things slow. How can I clear this up?
Would I have to delete the index? I'm okay with that, we're still in an early stage and won't lose anything important but notices.
