## Observing kube-router with Metrics

## Observing dropped traffic due to network policy enforcements
|
|
|
|
Traffic that gets rejected due to network policy enforcements gets logged by kube-route using iptables NFLOG target
|
|
under the group 100. Simplest way to observe the dropped packets by kube-router is by running tcpdump on `nflog:100`
|
|
interface for e.g. `tcpdump -i nflog:100 -n`. You can also configure ulogd to monitor dropped packets in desired output
|
|
format. Please see [the official ulogd documentation](https://kb.gtkc.net/iptables-with-ulogd-quick-howto/) for an
|
|
example configuration to setup a stack to log packets.
