tooling to provide: Event monitoring with metadata: When a packet is dropped, the tool doesn’t just report the source and destination IP of the packet, the tool provides the full label information of both the the sender and receiver among a lot of other information. Policy decision tracing: Why is a packet being dropped or a request rejected. The policy tracing framework allows to trace the policy decision viewing security policies, and configuring network monitoring behavior. Linux Kernel BPF Berkeley Packet Filter (BPF) is a Linux kernel bytecode interpreter originally introduced to filter network packets

This limitation is currently tracked at #12454 [https://github.com/cilium/cilium/issues/12454]

The policy tracing framework allows to trace the policy decision L7 policies at egress, the source identity context is lost as it is currently not carried in the packet. This means that traffic will look like it is coming from outside of the cluster to the receiving
