SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides in-depth analysis of Magento 2 cache configurations and performance to identify bottlenecks across FPC, Application Cache, Redis, and Varnish, enabling targeted optimizations and faster page loads.

Core Features & Use Cases

Cache Configuration Analysis: Assess status, backends, prefixes, and lifetimes for all cache types.
Redis & Varnish Diagnostics: Inspect connections, memory usage, hit rates, and eviction policies to tune performance.
Actionable Recommendations: Generate concrete optimizations and validation steps for improved cache hit ratios and reduced latency.
Use Case: When a Magento storefront experiences slow page loads, run this Skill to identify misconfigurations and propose remediation steps.

Quick Start

Run the Skill to perform a comprehensive cache health check against your Magento 2 instance and report findings.

FAQPage Schema

How do I diagnose Magento 2 cache performance issues across Redis and Varnish?▼

Diagnose Magento 2 cache performance by analyzing configurations and runtime metrics for FPC, Redis, and Varnish. The diagnostic process inspects connection status, memory usage, hit rates, and eviction policies to identify bottlenecks and generate actionable optimization recommendations.

Why does my Magento storefront experience slow page loads despite Varnish and Redis caching?▼

Slow Magento storefront page loads often stem from misconfigured cache lifetimes, incorrect backend prefixes, or poor Varnish and Redis eviction policies. A full-stack cache diagnostic evaluates these runtime metrics and configurations to pinpoint specific bottlenecks causing the latency.

What's the best way to check Magento cache hit ratios and Redis memory usage?▼

The best way to check Magento cache hit ratios and Redis memory usage is through a comprehensive cache health check using Magento CLI. This diagnostic assesses application cache backends, Redis connections, and Varnish hit rates to provide concrete tuning recommendations.

Do I need Magento CLI access to run a full-stack cache diagnostic?▼

Yes, you need Magento CLI (bin/magento) access to run a full-stack cache diagnostic. The analysis requires direct access to Magento CLI, Redis and Varnish details, and relevant cache configuration data to accurately evaluate cache types across development, staging, and production environments.

Can I use this cache diagnostic on Magento staging and production environments?▼

Yes, you can run this cache diagnostic on Magento staging and production environments. It evaluates full-stack deployments using FPC, Redis, Varnish, and backend cache types across these environments to generate targeted optimizations and validation steps for reduced latency.

What Magento cache configurations are checked during a diagnostic health check?▼

A Magento cache diagnostic health check assesses the status, backends, prefixes, and lifetimes for all cache types. It inspects Redis and Varnish connections, memory usage, hit rates, and eviction policies to generate concrete optimizations for improved cache hit ratios.
