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.

| tstats `summariesonly`   dc(All_Traffic.dest_port) as dc_dest_port  values(All_Traffic.dest_zone) as dest_zone min(All_Traffic.dest_port) as min_port max(All_Traffic.dest_port as max_port values(All_Traffic.action) as action  from datamodel=Network_Traffic.All_Traffic where NOT (All_Traffic.dest_port=443 OR  All_Traffic.dest_port=80 )  by All_Traffic.src_ip All_Traffic.dest_ip _time span=5m
| `drop_dm_object_name(All_Traffic)`
