Managing a network is a very big functional area along with performance, devicemaintenance, security, performance, monitoring, troubleshooting, plan of changeand etc. Among all of these monitoring plays a vital role. It can cover a wide area ofnetwork management. Monitoring is the only way to find out whether the networkis functioning according to plan. In order to know what is happening in a network,how its functioning at any given time, a network should have a logging system. Nowa day this logging activity is done by Network monitoring tool. It lets user know thestatus of the network at any given time. This logging can give the user a wide viewwhat can't be seen in general. For example the statistics of a week or month, even ayear. Monitoring is a very important issue in an organization network which aroseover the time.In this project we are going to implement some well known network monitoringtools in a real world scenario and we will investigate how this monitoring tool canhelp network administrators to monitor a network . Moreover, what kind ofinformation we can extract from a network by these tools.The purpose of this project is to get an overall idea about the importance of networkmonitoring and what are the facts need to be considered while monitoring anetwork. There are lots of pros and cons in monitoring a network. So choosing theappropriate tool for monitoring is very important. Monitoring a network with theleast effects on network performance is the best solution in case of monitoring.The outcome from these monitoring tools is a wide range of useful data andintegration of these data produces the status of the network at any give time.Moreover these data will be logged to create a statistical report. Different users suchas a network admin and organization can use this information from differentperspectives to make a network more efficient for users.
