Is this new? I don't recall seeing this before...
It seems to be a running total in real time that starts once you navigate to the Firewall page and not and all time total, but this is a nice add for troubleshooting for sure!
This MX is on 14.27, but I also see it on an MX with 14.19.
I have noticed this from time to time, but I manage dozens of organizations and also notice that I do not see it on some systems. I haven't bothered to try to find out why yet. I have also noticed a checkbox for 'logging' next to rules on some systems.
Yep been there for a while. Security Appliance>Firewall. I find it handy to validate how much traffic is getting blocked by the rule. Would be nice if they had similar functionality fo the switch ACLs.
I'm 99% sure it's been there for quite a while now.
Even before firmware version 14.x
I've checked some networks and the oldest firmware I could find in my networks with ACL Hit counts is 13.28
But i'm pretty sure it was there before that too.
