KQL Query sought for Source and Destination IP and TCP Port
Log analytics is ON and I wish to run a KQL query as described in the title. In terms of time duration it can be for last 24hours for example. This is for traffic going through Azure firewall.
I just want to be able to specify a host and destination IP address, with TCP port 443 for example.
I've searched, but nothing this specific found and I don't come from a 'script writing' background neither, though I do accept that must change going forwards.
