This bachelor's thesis deals with analysis, design and implementation of a system for network and services responses monitoring. The work is dedicated to two ways of tracking responses, an active one and a passive one. The active mode simulates the realistic requirements for services in the network and it measures time required for the operation. The passive method examines the response of services by means of listening on the network and by network traffic analyzing. Then, both of the methods store all consolidated data in databases. Management of monitoring and display of measured responses is provided by a web interface that allows each user to see monitored objects and to compare responses obtained by the active and the passive monitori...
