What are the readonlyrest_audit indices?

Hi Does anyone know what the readonlyrest_audit are? They are rather large and take up about 265 megs a day? Can I remove them all?

green open readonlyrest_audit-2017-09-22 XXX 5 0 638663 0 265.5mb 265.5mb

Thanks!

It’s the audit logs feature. By default it’s off, just remove it from your settings, if you are not interested.
