flowlogs-dump (like tcpdump)

How to run

From the root directory of the project:

Build the agent (the flowlogs client that uses ebpf) using:

make build

Build the flowlogs-dump-collector (the server that receives logs from the agent and dumps to screen) using:

go build -mod vendor -o bin/flowlogs-dump-collector examples/flowlogs-dump/server/flowlogs-dump-collector.go

Start the agent using:

sudo FLOWS_TARGET_HOST=127.0.0.1 FLOWS_TARGET_PORT=9999 ./bin/netobserv-ebpf-agent

Start the flowlogs-dump-collector using: (in a secondary shell)

./bin/flowlogs-dump-collector -listen_port=9999

You should see output such as:

starting flowlogs-dump-collector on port 9999
