New Features

KubeSkoop Web Console

We introduced KubeSkoop Web Console, a user-friendly Web UI that provides all functionality of KubeSKoop!

• Monitoring
  • Embedded Grafana Dashboard
  • Events
  • Network Graph (based on flow, packetloss and tcpretrans metric probe)
• Diagnosis
  • Connectivity Diagnosis
  • Distributed Packet Capturing
  • Latency Detection (Ping Mesh)
• Configuration
  • Node Configuration (for exporter config)

New probes

• tcpretrans: trace tcp retransmission

Improvements

• Add custom arguments for probes, to provide custom rules and feature switches.
• Concurrently write events to sink to improve the performance.
• Flow probe now can specify the interface from args.
• Refactor nettop to improve the performance of fetching pod info.
• packetloss, tcpretrans and flow metrics are now containing source and destination info in metric labels.
