Freento FPC Log + Advanced Analysis

Freento FPC Log Advanced Analysis is a tool for monitoring and analyzing the performance of Full Page Cache (FPC) in Magento 2. It allows logging FPC hits and misses at the page level, providing detailed insights in the admin panel. Additionally, the module analyzes full and tag-based cache clearing, tracking which tags were removed, when it happened, and with which call trace. This helps identify excessive cache clearing and optimize its usage.

Cache Optimization and Issue Diagnosis Directly in Production

• Logging FPC hits and misses helps identify pages that are not cached and take longer to load.
• Tracking cache tag clearing allows analyzing which cache elements are removed most frequently and checking for excessive cache purging.
• Includes cache clearing trace, enabling identification of the code that initiated data removal.
• Allows safe testing of FPC in production without interfering with user experience.

Why Is This Important?

Unstable Full Page Cache performance increases page delivery time by up to 10 times — from 100-250 ms to 1-2.5 seconds. Frequent FPC misses lead to higher server load and slower page loading, especially under high traffic conditions.

Benefits:

• Helps identify pages that are not cached and require optimization.
• Detects excessive cache clearing, reducing unnecessary regenerations.
• Reduces server load through more efficient FPC utilization.
• Improves store stability and predictability.
