Intro

Monitors the IPs that are bound to the machine. Returns Prometheus metrics with labels indicating whether the pre-configured set of IPs have been bound. Set a space-delimited list of IPs in the IP_LIST environment variable.

This is one solution for monitoring Virtual IP-based solutions where IPs might float around multiple hosts.

Running

rustup override set nightly
rustup update
export IP_LIST="127.0.0.1 192.168.0.3 192.168.0.2"
cargo run
