Mikroservis mimarisi ve konteyner teknolojilerinin y\u00fckseli\u015fiyle birlikte, Kubernetes (K8s) orkestrasyon platformu, modern uygulamalar\u0131n vazge\u00e7ilmez bir par\u00e7as\u0131 haline geldi. Ancak, Kubernetes ortamlar\u0131n\u0131n karma\u015f\u0131kl\u0131\u011f\u0131, izleme ve y\u00f6netim s\u00fcre\u00e7lerini zorla\u015ft\u0131rabilir. Geleneksel izleme y\u00f6ntemleri, dinamik ve \u00f6l\u00e7eklenebilir Kubernetes k\u00fcmelerinde yetersiz kalabilir. \u0130\u015fte bu noktada, Prometheus Operator devreye girerek Kubernetes ortamlar\u0131nda otomatik izleme ve alarm kurma s\u00fcre\u00e7lerini basitle\u015ftirir ve optimize eder.<\/p>\n
