This system queries network devices, such as switches and routers, for network traffic information. The most common method of network monitoring used today is through the Simple Network Management Protocol (SNMP). If you want to store and replay packets or load older packets into a viewer for analysis then you really need a packet sniffer. Once the packets have passed they cannot be recovered.

ManageEngine Network Topology Tool with OpManager (FREE TRIAL) A network monitoring system that uses Ping sweeps and SNMP processes to watch performance.

SolarWinds Network Performance Monitor EDITOR’S CHOICE While the main technique used by this network monitor is based on SNMP, the system also includes a deep packet inspection function.

Here is our list of the six best traffic analyzers: Letting packets pass by doesn’t necessarily mean that all chances for historical analysis are lost. The advantage of network analyzers is that they derive statistics from passing traffic without needing to store that traffic. Some network monitoring tools include a blend of these tools and some offer a bundle of network monitoring methodologies from which the user can choose. Network analyzers that examine passing packets.Network testing tools, such as Ping and Traceroute.

Performance monitors that use SNMP queries to get statistics from network devices.There are four types of network monitors:
