Nutanix Data Lens is a data analytics and security service designed for Nutanix Unified Storage (Files and Objects). Its Audit Trails feature provides a detailed, searchable log of all user and administrator activities on the file server. This includes events like file reads, writes, creations, deletions, and permission changes. Administrators can filter these audit trails by specific users, client IP addresses, file paths, and other criteria to generate precise reports on a user's activity, which directly addresses the question's requirement.

A. Prism Element Alerts menu: This menu displays system-level health and performance alerts for a specific cluster, not granular end-user file access activity.

B. Prism Central Activity menu: This menu tracks administrative tasks and events across the infrastructure (e.g., VM operations, policy updates), not end-user data interactions within Nutanix Files.

D. Files Console Usage: The Files Console provides high-level storage metrics such as capacity utilization, share count, and performance statistics, but it does not offer detailed, user-specific activity logs.

1. Nutanix Data Lens User Guide v2.3: In the "Audit Trails" section

it states

"The Audit Trails page displays a list of all the file and object activities that Data Lens has captured... You can filter the audit trail by user

file server

share

top-level directory

file path

or client IP address." (Section: "Monitoring File and Object Activity > Audit Trails")

2. Nutanix Files User Guide v4.4: The "Files Console Summary View" section details the information available

which includes "Storage Usage

" "File Server Health

" and "Performance." It does not mention user activity auditing

confirming this is not the correct tool. (Section: "Files Console Management > Files Console Summary View")

3. Prism Central Guide v2023.4: The "Activity Monitoring" section describes the Tasks view

which "provides an aggregated list of all tasks running in the registered clusters." This confirms its focus on infrastructure tasks

not user data access. (Section: "Prism Central Infrastructure > Activity Monitoring")

4. Prism Element Web Console Guide v6.7: The "Alerts Dashboard" section explains its function: "The Alerts dashboard displays a list of the alerts that have been generated for the cluster." This is for cluster-level events

not user file activity. (Section: "Health Monitoring > Alerts Dashboard")
