I want a dashboard to be created for port scan(to detect 2000 port scan attempts from one single IP towards single destination within 5 min)
I tried creating one dashboard but the values in the dashboard keep on changing every time the dashboard refreshes. I want a dashboard that will display all the port scan attempts for last 24 hrs satisfying the condition (2000 port scan attempts in 5 min) and the values in the dashboard should stay till 24 hrs.
