Zephyr allows the daily collection of your trend data to be displayed in the Trend Reports of individual releases. You can schedule when that automatic background process should be run. Based on the amount of data, this process could take a few minutes. All Zephyr functionality is fully available during this process.
On-demand Trend Data Collection
If required, you can re-collect trend data for a particular date or for a period of time. This on-demand data collection can be run for a specific type of trend. Based on the amount of data, this could take a while but it will be a background process and all Zephyr functionality will be available during that period.
