Problem

The expand=lastUsage API endpoint is not available in Jira Data Center, limiting users from easily accessing the last usage data for custom fields, which can hinder effective management and optimization of custom fields.

Suggested Solution

Develop an equivalent API endpoint for Jira Data Center that can provide the last usage information for custom fields. This functionality should mirror the expand=lastUsage endpoint in Jira Cloud to ensure consistency and ease of use across both platforms. See https://developer.atlassian.com/cloud/jira/platform/rest/v3/api-group-issue-fields/#api-rest-api-3-field-search-get

Why This Is Important

Having access to the last usage data for custom fields is crucial for administrators to maintain an organized and efficient Jira environment. It helps in identifying unused or infrequently used fields, thereby allowing for better resource management and potential performance improvements. Without this data, administrators may struggle to optimize their Jira instance, leading to clutter and potential performance issues.

Workaround

Administrators can use the knowledge base articles to manually retrieve custom field data and manage custom fields. Specifically, they can refer to "How to identify and list when a field value was changed in Jira and "How to retrieve all custom field configurations and custom field values in Jira Data Center from the database".
