En sık kullanılan performans counterları ve değerlerini aşağıdaki tablodan edinebilirsiniz;
Burada size tavsiyem bu değerleri tek tek elemek biraz zahmetlidir. Bir sunucuda ekledikten sonra perfmon aracından bu değerleri save settings as diyerek html olarak kayıt edebilirsiniz. Daha sonra bu html dosyasını diğer sunucularınıza kopyalayıp perfmon içerisine sürükle bırak yöntemi ile taşıyabilir ve bu sayede hepsine benzer değerleri takip edebilirsiniz. Tabiki yine en iyi yöntem bir izleme ürünü kullanmak olacaktır. SCOM ilk tercihim olmak ile beraber farklı ürünler kullanabilirsiniz.
