infrahub-analyzing-data（infrahub 分析数据）

Overview

Expert guidance for interactive data analysis against a live Infrahub instance. This skill uses the Infrahub MCP server to query, correlate, and reason over infrastructure data on demand — answering operational questions that span multiple node types and relationships.

Use this skill for any question of the form *"what does Infrahub currently know about X, and how does it relate to Y?"*

Typical question patterns:

• Compliance — "Are all devices following the naming convention?"
• Service impact — "Which services are hosted on devices in this rack?"
• Maintenance windows — "Which devices are currently in a maintenance window, and what depends on them?"
• Drift detection — "Which realized devices differ from their topology design?"
• Capacity — "Which racks are over 80% full?"
• Change impact — "What BGP sessions, services, and IPs depend on this prefix?"
• Inventory gaps — "Which devices have no platform or OS version recorded?"

For automated, pipeline-enforced checks that block proposed changes, see ../infrahub-managing-checks/SKILL.md. For repeatable scheduled reports exported as artifacts, see ../infrahub-managing-transforms/SKILL.md.

Project Context

If invoked with arguments (e.g., /infrahub:analyzing-data Which devices have no platform assigned?), treat the arguments as the question to answer.

When to Use

• Answering operational questions interactively via natural language
• Cross-referencing two or more node types to find relationships or gaps
• Investigating the blast radius of a change before executing it
• Auditing data quality across the inventory
• Producing one-time or on-demand reports for stakeholders
• Exploring schema structure and data before writing a generator or check

How It Works

The Infrahub MCP server exposes tools that let Claude query Infrahub data directly. The typical workflow:

1. Query — use MCP tools to fetch current state from Infrahub
2. Correlate — join, diff, or filter the data against a policy or second dataset
3. Reason — identify gaps, anomalies, or relationships
4. Report — surface findings with context and remediation hints

MCP Server Basics

When the Infrahub MCP server is connected, Claude can call tools such as:

• mcp__infrahub__infrahub_query — Execute a GraphQL query (primary tool)
• mcp__infrahub__infrahub_list_schema — List available node kinds
• mcp__infrahub__infrahub_get — Retrieve a specific object by ID or filters
• mcp__infrahub__infrahub_create — Create an object (remediation, on a branch)
• mcp__infrahub__infrahub_update — Update an object (remediation, on a branch)

# Example: find all devices in an active
# maintenance window
query MaintenanceDevices {
  MaintenanceWindow(status__value: "active") {
    edges {
      node {
        name { value }
        start_time { value }
        end_time { value }
        devices {
          edges {
            node {
              name { value }
              role { value }
              site {
                node { name { value } }
              }
            }
          }
        }
      }
    }
  }
}

Typical Analysis Workflow

1. Understand the question
   → "Which services depend on devices currently
      in a maintenance window?"

2. Identify the node types involved
   → MaintenanceWindow, DcimDevice, Service
     (or equivalent in your schema)

3. Query current state
   → mcp__infrahub__infrahub_query — one query
     per node type, or combined

4. Correlate the data
   → Join across node types, filter, count, diff

5. Report findings
   → Summarize with counts, list affected objects,
     suggest next steps
