How to use splunk for data monitoring and alert

[Sunjux]

Dear Splunkers:

I use nmap to monitor my device and contain these logs to Splunk,(every 6hrs)

These data only include ip and tcp open port,

E.g:

      ip_addr 1.2.3.4
      port_list 80\n433\n3389

Now I want to notify me when there is a new tcp port open(Compare the results of the previous two scans,which is the data twelve hours ago )

Which spl syntax should I use? Can someone give me any direction? thank you very much 🙂

Can you share some anonymised event as you have them in splunk?
