There are zero core plugins that do reporting. The only native reporting we have is the Dashboard Reports and the Exports from Tickets Queues/Searches. This is planned for after v2.0 so stay tuned!
Also, 1.15.x is super old and outdated so you need to upgrade ASAP to be inline with the latest security standards, to utilize the latest supporting requirements (PHP, MySQL, webserver), etc.
Cheers.
