What problem does it solve?
Troubleshoot Varnish Cache performance and stability problems by identifying likely failure archetypes and confirming them with Netdata MCP metric queries.
Core Features & Use Cases
- Failure-archetype diagnostic tree: Routes an investigation for thread pool exhaustion, cache stampede (thundering herd), ban list explosion, storage exhaustion, and workspace overflow.
- Operator-playbook-aligned triage: Uses the same Netdata operator playbook signal domains to drive structured, evidence-based debugging.
- MCP-based verification loop: Queries and validates Netdata varnish.* contexts (sessions/requests dropped, backend health, saturation/resources, cache hit ratio, thread management) to confirm whether remediation actually moved the signals.
Quick Start
Use the skill when you notice Varnish Cache behaving abnormally and want the agent to query Netdata via MCP, apply the diagnostic tree, and recommend targeted remediation: "Diagnose why our Varnish Cache is dropping sessions and requests, and tell me what to fix based on Netdata MCP metrics."
