Introduction The world ent65 t6 era of global communicatOFq2 The Intq/78 is rapidly growing and has become a significant fundamentd infrast66K/q2 intq6 era. Especially, World-Wide Web (WWW) is tq most importfi t service on tq Int65K5F Therefore, providing WWW services witsqK anyt6fifiLOq becomes a more importfi t issue. To achieve WWW server operat87 wit less server suspending period,tq6fi are manyt ools andsyst88 proposed so far. However, t,q stq6 require expertfiL andheuristq t tr administ/OfiKqt becausetaus t ols donot provide te comprehensive view of tq WWW server behavior. To ease te server administ68765q we developed a set of applicat768 t esticat tt WWW server performance in realtlq6 called ENMA [1] t]q stqfi6 for EnhancedNet work Measurement Agent The ENMA can measure several performance indices of tq WWW server such as a paramet2 of TCPconnectq2O and td tdq volume of tq WWW server processes, and providetd more precise view of tq server behavior in graphical forms.
