Batch Reporting
Batch reporting is available through the ftlm_batch_report
command.
Batch reporting is useful when the report period is long or there is a desire to have more
than one report shown on the web page.
Batch reports are persistent and static: the data they display is accurate as of the time they are built, and remain available until the report files are deleted from the disk.
You can create a batch report by either specifying a custom report or by specifying the types of tables, charts, and plots you wish to enable.

You may use batch reporting to configure a complex report with HTML format which includes the corresponding ftlm_batch_report commands, then incorporate such command (with proper modification) in a cron job (UNIX) to automate and schedule the report generation.
