Usage Center⚓︎

The Usage Center provides visibility into publishing activity across an organization and its namespaces. It allows users to review aggregate usage metrics for the selected organization, view namespace-level usage details based on their access permissions, and export namespace usage data.

Navigate to https://central.sonatype.com/publishing/usage to view Usage Center in Maven Central.

At the top of the page, users can select an organization from the organization dropdown. All usage data displayed on the page is scoped to the currently selected organization.

Usage Overview⚓︎

The Usage Overview section displays organization-level usage metrics for the selected organization. These values are aggregated sum across all namespaces in the organization.

Users can change the reporting period using the time-range dropdown. Usage metrics are available for Current Month, Last Month, and Last 2 Months:

  • Current Month: Shows usage data from the first day of the current calendar month through today.
  • Last Month: Shows usage data for the previous calendar month.
  • Last 2 Months: Shows usage data for the two completed calendar months immediately prior to the current month.

For example, if today is May 15:

  • Current Month includes May 1–May 15
  • Last Month includes April 1–April 30
  • Last 2 Months includes March 1–April 30.

Usage by Namespace⚓︎

The Usage by Namespace table lists the namespaces associated with the selected organization.

This table displays namespace-level usage metrics for the selected time period. However, the metrics shown for each namespace depend on the user's access to that namespace within the organization. A user may see restricted or unavailable usage data for namespaces they do not have permission to access.

Users can also export the Usage by Namespace table as a CSV file by clicking Export CSV.

Metric Definitions⚓︎

The Usage Center displays the following metrics:

  • Release Count: The total number of release events recorded during the selected time period. For example, if three separate releases were published in the selected month, the release count is 3.
  • File Count: The total number of files published across all releases during the selected time period. For example, if one release included 5 files and another included 3 files, the file count is 8.
  • Release Size: The total size of all files published during the selected time period. For example, if the published files were 200 MB, 300 MB, and 500 MB, the release size is 1 GB.

These metrics are shown in both the Usage Overview section and the Usage by Namespace table, based on the selected organization and time period.

Note

Since Maven Central publishing has historically been based on namespaces rather than organizations, organizations in the Usage Center have been created based on namespaces or group IDs and mapped to an organization.

If you notice a discrepancy between a namespace and its mapped organization, contact Central Support at central-support@sonatype.com.
