We're on 7.2.5 patch 2 IF 2. Today when I opened the Network Activity tab it was completely blank, no flow data of any kind. We have all of our flow data going to our NBAD appliance. We've never used this tab much but would like to make more sense out of it.
Any idea where I should go to start troubleshooting it? I opened a PMR but support has a reluctance to respond on Mondays it seems...I've checked with our Networking team and they didn't make any changes this weekend...I get no results on flow data in any searches going back 7 days.
I've never troubleshot this appliance and have no idea where to start. What service supports NBAD?
