Depending on the rule that's being matched, it may not be possible to run a report.
The main reason being SmartEvent generally does not index connection logs from the firewall blade, only sessions (generally things that are tracked by a higher-level blade like App Control).
That said, I can think of a couple ways to do this:
- Use SmartView to export the last million logs against the relevant rule into a CSV file, where you can import to Excel or similar.
- You can also get some rough statistics in SmartView, but you'd have to scroll through the various log entries to get them to load into memory so the stats can be shown.
