## What it is
Goldpinger is a Kubernetes debugging tool that runs as a DaemonSet and makes calls between its instances to test and visualize network connectivity between cluster nodes. It exposes Prometheus metrics and a UI graph for troubleshooting connectivity and latency issues.

## Use cases
- debug network connectivity between kubernetes nodes
- visualize cluster networking health as a graph
- alert on node-to-node connectivity failures with prometheus
- troubleshoot slow network paths in a k8s cluster
- monitor packet loss and RTT between nodes
- run chaos engineering experiments on cluster networking

## When to choose
- you run Kubernetes and need to diagnose node-to-node networking issues
- you want Prometheus metrics and Grafana dashboards for cluster connectivity
- you need a lightweight, self-hosted network health checker for your cluster

## When to avoid
- you need application-level or service-mesh traffic monitoring rather than node connectivity
- you are not running Kubernetes
- you need deep packet inspection or flow-level network analysis

## Facets
- artifact type: service
- maturity: active
- function: monitoring, alerting, networking, analytics
- domain: monitoring, networking
- platform: self-hosted, go
- tags: kubernetes-networking, daemonset, prometheus-metrics, connectivity-check, grafana, cluster-debugging, kubernetes, devops, containers, docker
