Prometheus Conntrack Metrics

prometheus-conntrack exposes conntrack metrics for docker containers or kubelet pods.

For example, the series conntrack_workload_connections{destination="192.168.50.4:2375",container="my-container",protocol="TCP",state="ESTABLISHED"} 2 means that the container "my-container" has two connections established with tcp://192.168.50.4:2375.

You can run prometheus-conntrack in a container or run the binary directly.
