How to collect network statistics using a Floodlight controller?

Hi,
Using the floodlight controller in Mininet, how can I collect network statistics?

The documentation only states how to collect bandwidth data: Floodlight REST API – Floodlight Controller – Confluence (atlassian.net)

Are there APIs available that I am unaware of that allows collection of other statistics such packets and flow statistics in a particular switch?

Thank you for your help.
