Visualize and Analyze Network Traffic of BOSH-Releases in Real-Time
summary
Built an open source stack that captures packets from VMs via Packetbeat BOSH add-on, stores events in Elasticsearch + Kibana, and renders live topology with Vizceral real-time graph while driving failures with turbulence chaos tests. The pipeline reveals concrete surprises: three-node ping release shows unexpected NTP and DNS endpoints; an AZ kill causes etcd nodes to fire ~60 DNS queries/sec to infra DNS; BOSH resurrector recovers services but with long delays. The setup works for spotting and drilling into real network behavior.
