View flow logs in the Calico Whisker web console.

i’ve been mucking about with calico on my #homelab #kubernetes cluster, and it took me far far too long to visit the whisker console: https://docs.tigera.io/calico/latest/observability/view-flow-logs

this is unbelievably helpful for debugging firewall rules

i’m very tempted to switch to calico on my non-k8s systems now (e.g. Linux gaming PC), so i can be back to only having 1 firewall abstraction in my brain

    thanks, i hadn’t actually heard of ntop / ntopng before!

    i believe ntopng works everywhere independent of whether calico is installed or not (and even calico is a Kubernetes-compatible and Kubernetes-optional system, just like ntopng)

    but, calico whisker displays networking information made available by the rest of calico, so it’s able to give you a live display of when a firewall rule managed by calico is allowing or blocking traffic

    i think this particular feature is absent from ntopng, but i could be wrong
