Redis Monitoring Araçları

Mertcan GÖKGÖZ

Redis, modern uygulamalarda kritik bir rol oynayan bellek tabanlı veri depolama sistemidir. Yüksek performansı ve ölçeklenebilirliği ile bilinen Redis’in etkin şekilde izlenmesi, sistem performansını korumak için hayati önem taşır ve mutlaka monitor edilmesi gereklidir.

Redis Nasıl İzlenir?

Redis, monitoring amaçları için çeşitli komutlar sunar:
