Kademlia Exporter

Exporter exposing Prometheus metrics for libp2p Kademlia distributed hash tables.

Information below is likely outdated. Code is the source of truth.

Quickstart

cargo run -- --config-file config.toml

curl localhost:8080/metrics

Ip localization

Optionally the exporter can estimate a peers location through the Max Mind Geo DB. See max_mind_db_path parameter in config.toml.

Cloud provider

Optionally the exporter can estimate the cloud provider a peer is hosted in via a list of CIDRs. See .assets/cidrs.r to generate a list and cloud_provider_cidr_db_path parameter in config.toml to specify the generated .csv file.
