Best Network Monitoring Tools

Network monitoring tools are those constantly monitor components and notify the network administrator in case of slow or failing or outages. Network monitoring tools perform task such as data flow analysis, network auditing and vulnerability. Any organizations cannot be called professional, if it lacks network monitoring tool. Network Monitoring tools are capable of tracking physical health of devices such as switches, servers, networked printers, routers and other devices that are attached to networks. Network Monitoring tools might include dashboard view of several devices mentioned above based on the design and feature of the tool used. Even with these tools a simple vulnerability can cost millions.  Following are few Network Monitoring tools which are considered as one of the best in the industry.
