Hello,
I believe you have already done the storage side configuration for this CIFS audit.
https://kb.netapp.com/on-prem/ontap/da/NAS/NAS-KBs/How_to_set_up_NAS_auditing_in_ONTAP_9
You can run a “vserver audit show” to check where the logs are getting stored.
cluster1::> vserver audit show
Vserver State Event Types Log Format Target Directory
----------- ------ ----------- ---------- --------------------
vs1 false file-ops evtx /audit_log
You can map the same Target Directory path on to one of your windows clients to access the audit logs.
The audit file gets created automatically within the same vserver while configuraing the audits.
Hope this information helps.
