View Bucket Metrics

Describes how to view bucket statistics such as Total Bucket Size and Number of Objects.

Using the CLI

Use the mc stat command to view bucket statistics. Use the mc ls command to list objects with versions.

Using the Object Store Interface

Login to the Object Store Interface as the administrator or as the root user.
Click the bucket icon from the left pane.
From the Buckets page, click the bucket for which you want the statistics displayed. The statistics are displayed in three tabs:
- Bucket Details: Displays the properties of the bucket set at the time of bucket creation or modification.
- Bucket Metrics: Graphs the changes over a specified frequency in the storage space used for the bucket, and the number of objects contained in the bucket. Supported frequencies are 24 hours, Last Week, Last Month and Custom. With Custom, enter a date range to view the graphs.
