Unable to discard hostfs/etc/sv/monit/.kube/ path on my PKS environment

I am using Pivotal Kubernetes clusters on vmware and collecting logs on Splunk. I installed auditbeat and tried to exclude hostfs/etc/sv/monit/.kube/ path but never managed to discard it at file_integrity module. I tried different regex but somehow auditbeat still sending logs related with this directory.
Ant tips will be appreciated.
