View HDFS Snapshots

The HDFS Snapshot page displays information about all directories where snapshots are enabled.

For details about HDFS snapshots, see HDFS Snapshots.

A snapshot is a read-only copy of a directory captured at a specific point in time. It helps preserve data for backup and recovery, auditing, or comparison purposes.

Enable FS Directory Snapshot Reporting

Enabling this helps you collect and display detailed FS directory insights as part of its analytics and monitoring dashboards.

1. On the Pulse Node, check if the file ad-fsanalyticsv2-connector.yml exists at the following path:

/data01/acceldata/config/docker/addons

2. If the file does not exist, generate it by running the following command:

accelo admin makeconfig ad-fsanalyticsv2-connector

3. Once the file is available, open ad-fsanalyticsv2-connector.yml and locate the environment section.
4. Add the following entry under the environment section to enable the snapshot directory reporting feature.

FSANALYTICS_SNAPSHOT_DIRECTORY_REPORT_FLAG=true

This flag enables the FS Snapshot Directory Report functionality within the FS Analytics connector.

Steps

1. In the Pulse UI, go to HDFS > Snapshot.
2. On the Snapshot page, you can see the HDFS snapshots details.
