Simple Grafana Dashboard

[PMaynard]

This is a simple setup testing out softflowd exporting netflow data to nfcapd, which in turn makes prometheus metric available. Docker is used to spin up prometheus and grafana. The defaults should work ping me if not and we can figure it out.

You can skip the softflowd step and use nfcapd to capture netflow data if you wish.

Note: This was run on Fedora using podman. Some of the docker commands may be specific to podman and Fedora setup.

Netflow Exporter
sudo bin/softflowd -v 9 -n 127.0.0.1:9995 -i enp4s0 -d

Netflow Collector
nfcapd -v -w data/ -m /tmp/nfsen.sock

Prometheus Metrics Exporter
go build && ./nfsen_exporter

Prometheus Instance
docker run --replace --name prometheus -d -p 9990:9090 -v ./config/prometheus.yml:/etc/prometheus/prometheus.yml:z prom/prometheus
