SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

It diagnoses VMware vSphere incidents like CPU starvation, memory pressure cascades, storage latency cliffs, NUMA penalties, and snapshot accumulation with a structured, evidence-driven triage flow.

Core Features & Use Cases

  • MCP-driven troubleshooting for vSphere signals: Queries Netdata via MCP to pull the key host/VM signals needed to identify the dominant failure archetype.
  • Operator-playbook-based diagnostic tree: Applies the Netdata operator playbook logic to route an agent through the correct domain rules (CPU, Memory, Storage, Network, Availability/vCenter services, Hardware/Host Health, and others).
  • Load-bearing verification contexts: Re-runs targeted MCP verification queries to confirm remediation actually moves signals back to expected ranges.

Quick Start

Use the troubleshoot-vmware-vsphere skill when investigating a VMware vSphere incident like widespread slowness or VM freezes by asking the agent to triage “a suspected storage latency cliff for host X over the last 15 minutes using Netdata via MCP.”

FAQPage Schema
How do I troubleshoot a VMware vSphere performance incident using Netdata?

To troubleshoot a VMware vSphere performance incident using Netdata, this skill applies a structured diagnostic tree via MCP to query host and VM metrics, identifying failure archetypes like CPU starvation or storage latency cliffs for fast triage.

What causes memory pressure cascades and CPU starvation in vSphere VMs?

Memory pressure cascades and CPU starvation in vSphere VMs are common failure archetypes caused by resource exhaustion. This skill identifies them by correlating anomaly rankings from Netdata signals across VM-level and host-level contexts during the incident window.

How do I diagnose a suspected storage latency cliff on a vSphere host?

To diagnose a suspected storage latency cliff on a vSphere host, ask the agent to triage the host over a specific time window using Netdata via MCP, which will pull load-bearing metrics and route through the storage domain diagnostic rules.

Can I use this vSphere triage skill for on-call capacity planning and root cause analysis?

Yes, you can use this vSphere triage skill for on-call root cause analysis. It applies Netdata operator playbook logic to identify failure archetypes and verifies remediation by re-querying load-bearing contexts to confirm metrics return to expected ranges.

Does this vSphere troubleshooting skill require an MCP connection to Netdata?

Yes, this vSphere troubleshooting skill requires an MCP connection to Netdata. It depends on MCP calls for metric discovery, metric querying over a defined time window, anomaly ranking, and remediation verification.

What are the limitations of using anomaly ranking for vSphere NUMA penalty troubleshooting?

When troubleshooting vSphere NUMA penalties, the limitation is that diagnostic accuracy depends on the available Netdata signals. The skill routes through hardware and host health domain rules, but cannot identify archetypes if the required load-bearing metrics are missing.
