How do I map Kubernetes pods to OVS ports?

The analysis automatically checks interface external-ids for iface-id and maps veth host-side names to identify which OVS ports correspond to specific pods.

Does it support compressed sosreports?

Yes, the analysis script can process both extracted sosreport directories and .tar.xz archive files directly.

Can this skill help with OVN troubleshooting?

Yes, it includes specialized logic for OVN-managed bridges (br-int) and knows which internal tables to ignore versus which indicate real policy drops.

Do I need ovsdb-tool installed to use this skill?

ovsdb-tool is required for full database analysis and custom queries, but the skill can fall back to a 'flows-only' mode that processes text files if the tool is unavailable.

분석 및 모니터링

Analyzes Open vSwitch data from sosreports to troubleshoot networking issues, packet drops, and flow performance.

소개

The OVS Network Analyzer skill enables Claude to perform deep diagnostics on Open vSwitch (OVS) environments using data collected from sosreports. It processes OVS databases (conf.db) and OpenFlow text files to identify active packet drop flows, map Kubernetes pods to network interfaces, and audit bridge topologies. By providing structured insights into datapath health, tunnel configurations, and port statistics, this skill helps engineers quickly pinpoint root causes in complex virtualized networking environments like OpenShift and Kubernetes.
