Versions:
Hubble 0.12.0 is a purpose-built command-line interface released by the Cilium project to deliver deep, real-time visibility into cloud-native networking and security events controlled by the Cilium eBPF-based datapath. Positioned within the Network Monitoring & Troubleshooting category, the tool streams fine-grained flow, policy, service-map and DNS metadata directly from every node in a Kubernetes or container cluster, letting operators observe packet paths, label-based policy decisions, dropped connections, HTTP/gRPC request traces, and TCP retransmissions without injecting sidecars or altering application code. Typical use cases include rapid service-to-service connectivity debugging, verification of NetworkPolicy enforcement, latency analysis across micro-services, incident response forensics, and continuous compliance auditing; DevOps teams often pair Hubble CLI output with Grafana dashboards or export it to SIEM platforms for longer-term trending. Although only one major version line exists—0.12.0 being the current milestone—the utility is updated in lock-step with Cilium releases, ensuring that new eBPF features such as transparent encryption status or DNS-based security rules are immediately observable. The lightweight binary is distributed under the Apache 2.0 license and is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
