> HI TEAM, I am using ELK version 7.0. Facing an issue with prune filter. I need to blacklist exact nested fields coming from filebeat. When i tried with below format, prune is unable to blacklist host.architecture field. Example: prune { blacklist\_names =\> ["^[host][architecture]$" ] } Regards, GR.
