Data Lens Hosted

Last updated: 2022-12-14

Nutanix Data Lens

Important: Data created with an early access (EA) version of Data Lens will be removed with the completion of the EA program. The data will not be available in the general availability (GA) versions.

Nutanix Data Lens™ (Data Lens) provides a cloud-hosted analytics and monitoring service for all of your file servers hosted on Nutanix Files. Data Lens centralizes data from all of your clusters connected to Pulse, across various data center locations. Cloud resources reduce scaling constraints, as the Cloud is not dependent on the file server resources, letting you have near-real-time analytics and alerts even for load-heavy file servers of more than 250 million files and over 500 TB of storage. Hosting File Analytics on premises limits the service to local file servers only. In contrast, Data Lens functions on a global level, in a cluster-neutral environment, without being tied to a single Nutanix cluster.

Procedure

  1. In the Data Lens web console, click the gear icon > Define Anomaly Rules .
  2. In the Anomaly Email Recipients field, enter a comma-separated list of email recipients for all anomaly alerts and data.
    Note: Data Lens sends anomaly alerts and data to recipients whenever Data Lens detects an anomaly.
  3. To configure a new anomaly, do the following in the indicated fields:
    1. Events : Select a rule for the anomaly from one of the following:
      • Permission changed
      • Permission denied
      • Delete
      • Create
      • Rename
      • Read
      The event defines the scenario type for the anomaly.
    2. Minimum Operations % : Enter a percentage value for the minimum threshold.

Ransomware Protection

Protecting your file server against 0-day ransomware detection and protection.

Caution: Ransomware protection helps detect potential ransomware. Nutanix does not recommend using the Data Lens ransomware feature as an all-encompassing ransomware solution.

Data Lens scans file audit events for ransomware in near real time and notifies you in the event of a ransomware attack once you configure email notifications. Ransomware protection includes signature-based and event-pattern-based ransomware detection.

Signature Detection

Signature-based detection uses the Nutanix Files ransomware file blocking mechanism to identify and block file renames whose extension and file names match ransomware signatures carrying out The blocking of file renames helps to identify file malicious activity by containing the ransomware attack from further infecting
 the files . The ransomware file blocking mechanism uses a dynamically curated list of signatures that frequently appear in ransomware files. The curated list is dynamically updated as new ransomware signatures are available. You can also modify the list by manually adding or removing signatures.

Event Pattern Detection

Event-pattern-based ransomware protection looks for audit events in near real time to identify potential ransomware attacks. Configuring auto-remediation allows you to block malicious clients from accessing all shares. In addition to that customers will also have the option to put the files in Read-Only mode where no clients will be able to do any write operations to the shares . Customers are recommended to upgrade to Files 4.2 to use advanced auto-remediation features as described above containing the ransomware attack from further infecting the files.

Note: Customers are recommended to upgrade to Files 4.2 to use advanced auto-remediation features.

Data Lens also monitors shares for self-service restore (SSR) policies and identifies shares that do not have SSR enabled in the ransomware dashboard. You can enable SSR through the ransomware dashboard.

Ransomware Protection Dashboard

The Ransomware dashboard includes panes for viewing threats summary and its details, managing and configuring ransomware protection, managing recovery settings, viewing blocked clients (users or client IP addresses), and viewing and updating blocked file signatures.

The Ransomware dashboard includes the following sections:

  • The Threats Summary pane displays the highlighted threats and its details (impacted shares, users, client IP address, and impacted files). You can view the threat summary for last 24 hours, last 7 days, last 30 days, and last one year. By default, last 24 hours summary is selected. Click the View Details link to see the threat details and impacted files.
  • The Recovery (SSR) Enablement by Shares pane for viewing and enabling Self Service Restore (SSR). SSR snapshots are used for data recovery. To protect the shares with configured SSR policy, enable SSR for the shares, see Enabling SSR.
  • The Blocked Entities pane for viewing the blocked IP addresses and users suspected to be the source of ransomware attack.
  • The Blocked Files Signatures pane for viewing the number of blocked ransomware signatures configured on the subscribed file server. Click Download List (.csv) to download a list of blocked ransomware signatures. To update blocked signature list, click Update Blocked Signature List or click Settings > Update Signature List . See Updating Signature List
    Note: If a File Server fails to update the signatures, then the number of blocked file signatures is not updated. The previous count is displayed in the Blocked Files Signatures .
  • Click Unblock to revert access of File Server from Read Only mode to Read Write mode.
  • To enable or disable, and configure ransomware protection, click Settings . See Enabling Ransomware Protection and Configuring Ransomware Protection Policy.

Smart Tiering

Manage hot, warm, and cold file server data.

Use Smart Tiering to maximize the available file server space by moving cold data from the file server to an object store. Nutanix supports using Nutanix Objects, AWS Standard, AWS IA, or Wasabi (S3 compatible storage) as the object storage, which you must configure before setting up a tiering profile, for details on setting up Nutanix Objects, see the Objects User Guide .

Tiered storage does not contain the full data set. The full metadata and pointers to tiered data remain on the primary storage. However, tiering cold data to an object store does provide storage cost benefits, which you can calculate using the cost savings widget in the Data Tiering tab. You can recall tiered data from the object store by configuring an auto-recall policy during tiering policy creation, or by recalling data manually. You can also specify retention policies that indicate how long deleted data remains in secondary storage prior to permanent deletion.

Note: If you have Files version 4.2.0 and above you will be able to create a tiering profile with AWS Glacier storage class in addition to Object Store, AWS, and S3 compliant storage classes.

Do the following to enable tiering on the file server:

  • Ensure that you have enabled the file server in Data Lens, see Data Age Dashboard.
  • Review the "Limitations" section.
  • Review the Smart Tiering Requirements and Recommendations section.
  • Configure the tiering location and profile, see Configuring a Tiering Location.
  • Configure the tiering capacity threshold, see Setting a Capacity Threshold.
  • Configure a tiering criteria policy, see Creating a Tiering Policy.

Limitations

  • You can only have one tiering profile and tiering location per file server.
  • You can initiate only one tier and one recall job at a time.
  • You cannot evict tiered file data from the primary storage until all snapshots containing the file expire.
  • You cannot tier files that are smaller than 64 KiB or larger than 5 TiB.
  • You cannot write to tiered (offline) files.
  • You can only configure tiering at the file-server level.
  • You can only manually recall a maximum of 100 files at a time.
  • After re-enabling versioning, tiering operations need a minimum of 10 minutes to resume.
  • Files cannot compress data while tiering data to the object store.
  • Files does not tier sparse files.
  • The manual tier and recall operations have a timeout of 10 days, after which Data Lens terminates the operation. To continue the tier or recall operation for the remaining files, restart the operations.

Terminology

  • Capacity threshold – The percentage of file server capacity you must reach to trigger tiering operations.
  • Object store – Secondary storage service.
  • Recall – Migrating data from secondary to primary storage manually or through an auto-recall policy.
  • Tiering – Migrating cold data from primary to secondary storage.
  • Tiering profile – The secondary storage location configuration, which includes the object store, security keys, the storage bucket, and other details.

Smart Tiering Requirements and Recommendations

Meet the indicated requirements to configure and administer tiering.

General Requirements

  • Enable versioning on the object store bucket.
  • Meet the compatibility requirements as described in the Data Lens Release Notes .

Network Requirements

  • All file server VMs (FSVMs) need to access insights.nutanix.com through Pulse.
  • All FSVMs need to use DNS to resolve the name insights.nutanix.com .

AWS Simple Storage Service (S3) Requirements

  • List and write on object

Nutanix Objects Object Store Requirements

  • Use the bucket owner secret and access for tiering.
  • Ensure the owner has read and write permissions.

Security Recommendations

Nutanix recommends using the following security best practices:

  • Implement security best practices for AWS S3 as described on the AWS documentation portal.
  • Do not use the same bucket for storing non-Nutanix Files data.
  • Do not manually delete or overwrite any object in the bucket, as this results in data loss.
  • Disable the object lock.
  • Enable encryption on the bucket.
  • Have the permissions to query the bucket location.
  • Do the following when changing security keys:
    • Ensure that both keys are valid when changing from key1 to key2.
    • Retire key1 from s3 only after updating key2 on the file server.
  • On AWS, Files sets the life-cycle rule on the bucket to garbage collect deleted objects. Do not overwrite or remove the rule from S3. Do not apply another life-cycle rule to the bucket.
  • For Nutanix Objects, provide security keys of the owner of the bucket.

Isilon Integration

Use Data Lens as a lightweight analytics solution for file servers on Dell EMC Isilon, a third-party file server software.

Note: The Dell EMC Isilon integration is a technical preview feature and should not be used in a production environment. You might not be able to retain audit data or upgrade file servers from technical preview to general availability (GA) versions.

The Data Lens integration with Isilon deploys an agent VM in the third-party environment of the Isilon file server. The agent VM combines the capabilities of a syslog server and Isilon's incremental scan to receive audit events, scan data, and send the heartbeat of the container for health monitoring. Nutanix also collects insights data from your Isilon file server using Pulse. Before enabling the Isilon file server on Data Lens, you must consent to insights data collection, refer to "Nutanix Insights" in Support Portal Help.

As a lightweight analytics and monitoring solution, Data Lens for Isilon currently does not include a full feature set, see Isilon Technical Preview for a list of unsupported features. As a result, the Data Lens UI for Isilon includes fewer widgets. Some of the supported features include audit trails, capacity trends, and heat monitoring. UI updates include a column listing the vendor in the file server table on the Global Dashboard and a new Registered Agents view for monitoring all registered agents. If the agent VM is down for 24 hours, an automated alert goes out to Nutanix Support.

Deploying and managing Data Lens for Isilon requires the following:

  • Installing an agent VM, see Installing an Agent VM.
  • Enabling the Isilon server and accepting the license agreement, see Enabling a File Server.
  • Monitoring the registered agent VM in the Registered Agents view, see Isilon Technical Preview.
  • Configuring a syslog server in the Isilon environment. See the EMC Isilon Auditing Guide for steps to configure a syslog server.

Isilon Technical Preview

Technical preview of the Data Lens integration with Dell EMC Isilon.

This document describes the user experience for Data Lens with Isilon.

Lightweight Feature Set

Data Lens for Isilon provides general storage capacity reporting and audit visibility.

The Isilon integration does not include the following elements and features:

  • Share-level details in the main dashboard
  • Smart Tiering
  • Anomaly detection
  • Ransomware protection

The agent VM has the following limitations and restrictions:

  • You cannot change the name of the agent VM.
  • You cannot clone the agent VM.
  • If you delete the agent VM, any files or directories on the VM are also deleted.
  • The Data Lens UI does not register changes to the agent VM IP address. Re-run the registration command to display the updated IP address.
  • A backward slash in a file name causes the name and parent directory of a file to display incorrectly in audit trails.

Registered Agents View

Clicking the gear icon > Registered Agents displays a tabular view of all the agents in Registered Agents view. The following describes the columns in the table of the Registered Agents view:

Table 1. Registered Agents View
Column Description
Name Agent VM name
IP address IP address of the host where the agent VM is registered.
ID Unique identifier for the agent VM.
