Network Troubleshooting Tools
Network troubleshooting tools are among the most important products for
network professionals. So many businesses depend so much on their networks that even a short interruption in service can have major consequences. A network administrator should have as much help at his or her disposal as possible. Network tools for monitoring are among the most common and most useful network tools around.
Network monitoring tools allow administrators to sort out traffic problems and keep watch on external threats. Common network troubleshooting tools include Simple Network Management Protocols (SNMP) and Intrusion Detection Systems (IDS). These resources give network professionals a broad outlook on the data flow within a given network, and can often be used to pinpoint problems and DoS/DDoS attacks alike. These systems are designed to produce alerts when network activity becomes anomalous.
While SNMP and IDS are certainly useful, some think they give too broad a picture of what is going on in a network. The systems work with the statistical picture of the traffic on the network. To actually monitor the packet activity of a network, one needs a protocol analyzer. Such a system will give a much more detailed view of network activity, allowing him or her to actually "see" what is going on, as opposed to receiving a report on traffic patterns. This level of detail is more useful in solving certain networking problems.

Troubleshooting tools for latency include running a traceroute or sending a "ping," two activities that can help to determine the roots of network slowdowns. Some of the best network troubleshooting tools are located right in the head. Common sense can solve a whole host of problems (unplugged cables, for instance), and should be used as the first line of defense against network problems.
