    Why monitor PHP-FPM?

    PHP-FPM (FastCGI Process Manager) handles PHP request processing for millions of web applications. Monitoring PHP-FPM is essential to detect slow scripts, manage process pool sizing, prevent memory exhaustion, and maintain application responsiveness.

    Importance of PHP-FPM Monitoring

    PHP powers 77% of websites. Without monitoring, slow scripts, memory leaks, and worker exhaustion can bring applications to a halt.

    • Detect slow PHP scripts before they impact users
    • Right-size process pools based on real data
    • Prevent memory exhaustion from leaky scripts
    • Monitor listen queue to avoid request drops
