A command for inspecting OVN network databases collected from an OpenShift cluster. OVN is the software that describes virtual network switches, routers, ports, and access rules.

It lists logical switches, pod ports and IPs, access-control rules, routers, and supports custom database queries for a must-gather.

It makes stored network topology and configuration easier to examine when diagnosing cluster networking problems.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00013	$0.02541

Security

Grade B, and why

ovn-dbs scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

Name

must-gather:ovn-dbs

Synopsis

/must-gather:ovn-dbs [must-gather-path] [--node <node-name>] [--query <json>]

Description

The ovn-dbs command analyzes OVN Northbound and Southbound databases collected from clusters. It uses ovsdb-tool to query the binary database files (.db) collected per-node, providing detailed information about the logical network topology, pods, ACLs, and routers on each node.

The command automatically maps ovnkube pods to their corresponding nodes by reading pod specifications from the must-gather data.

Two modes of operation:

Standard Analysis (default): Runs pre-built analysis showing switches, ports, ACLs, and routers
Query Mode (--query): Run custom OVSDB JSON queries for specific data extraction

What it analyzes:

Per-zone logical network topology
Logical Switches and their ports
Pod Logical Switch Ports with namespace, pod name, and IP addresses
Access Control Lists (ACLs) with priorities, directions, and match rules
Logical Routers and their ports

Important: This command only works with must-gathers from clusters, where each node/zone has its own database files.

Prerequisites

The must-gather should contain:

network_logs/
└── ovnk_database_store.tar.gz

Required Tools:

ovsdb-tool must be installed (from openvswitch package)
- Check with: which ovsdb-tool
- Install: sudo dnf install openvswitch or sudo apt install openvswitch-common

Analysis Script:

The script is bundled with this plugin:

<plugin-root>/skills/must-gather-analyzer/scripts/analyze_ovn_dbs.py

Where <plugin-root> is the directory where this plugin is installed (typically ~/.cursor/commands/ai-helpers/extensions/must-gather/ or similar).

Gemini will automatically locate it by searching for the script in the plugin installation directory, regardless of your current working directory.

Implementation

The command performs the following steps:

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
