I'm new to ELK stack. Our server is running out of disk space and we have a cronjob running to delete the indices.
1 1 * * * /usr/local/bin/curator /root/.curator/action_remove_old_logs.yml
But what is occupying more on the disk is the data under the path,
where I see many random named folders like below
So what are these and is it safe to remove these folders? Please advice.
