I am doing an experiment at home to capture Internet traffic for all of my devices in my house connected to my home wi-fi. I heard in a conference that a guy setup Splunk Streaming on his splunk instance and was able to capture all traffic between his wireless router and any device in his house.
sourcetype="stream:ip" src_ip="192.168.1.16"
| stats count by dest_ip
I put this quick query together but I don't think I'm capturing everything, but I'd also like to have splunk resolve the Dest_IP
For example, if I pull up Google.com, I'd like to see in a Splunk Table "google.com" and not "172.217.5.78"
my results are as follows
Yes, assuming DNS is accessible by the search head, just add this to the bottom:
... | lookup dnslookup clientip AS dest_ip
