SonicWall Analytics On-Premises (for syslog based Reporting and analysis) is the latest version, replacing the older Analyzer Reporting Software. It uses the same syslog information sent by the firewall, and provides both on-demand, and scheduled report.
Deployed as a virtual appliance you need to have an ESXI (VMware) or Hyper-V environment - unfotunately no Windows version. Both hypervisors are available without cost, but you need to contact the relevant vendor for further information on this.
We're still awaiting documentation so this will be updated when avaialble.
