Ben dinledim beri Clint Huffman yazdı PAL kez bir podcast üzerinde, Perfmon Günlükleri analiz etmek için bir yardımcı program. Tüm üretim uygulama sunucularımızda Uçuş Kaydedicisi dediğim şeyi ayarladım. Bu uygulama, sorunları teşhis etmek ve trendleri izlemek için çok kullanışlı olmuştur.
Aşağıda, otomatik temizlemeli bir Perfmon Collector ayarlamak için kullandığım komut dosyası ve günlük temizlemesi var. İstenirse, toplanacak performans sayaçlarını (her satırda bir tane) veya bir PAL Eşik XML dosyasını listeleyen bir dosya beslenebilir. PAL Threshold dosyalarını kullanmayı seviyorum.
