Hello, I just posted a fix at: http://www.splunkbase.com/apps/All/4.x/app:Cisco+Firewalls+Add-On
The new dashboards should still allow you to view the information when the event-typer misbehaves. Let me know if you have any issues with this update or have any questions.
It runs, climbs to %100 and then reports as done. The only dashboard that populates is the bar graph for Firewall events over time. The others remain blank (denies by source, accepts by source, etc)
