A Network Performance Monitor is a tool to improvise the performance of network server. It can track Central Processing Units (CPU) load, memory usage, available disk space, bandwidth utilization, traffic and more. It is most appropriate for monitoring the usage of servers, switches, routers and historic graph of a network performance. It can read traffic data from router and can also displays a usage chart of last 96 hours or 365 days or 12 months. Users can also set the Network Performance Monitor tool to provide a daily report of each sensor. The monitor alerts a user on traffic usage, bandwidth usage, Packet Loss and more. It has a capacity to monitor from one single server to hundreds of elements. Generally, being an agent-less tool, it does not install any outside element on the network component being monitored or on a server. All the monitoring is executed from an Engineer Work Station or the Network Operation Centers (NOC) or any Central location.

The Network Performance Monitor is highly capable of collecting and monitoring traffic stats from the devices that backup Simple Network Management Protocol (SNMP). Some devices that do not backup SNMP can also be monitored such as Packet Loss and Network Latency. Most Network Performance Monitors can monitor about 10 to10, 000 nodes and interfaces from a single server at a time and there is no limitation on maximal number of interfaces and nodes that can be monitored.

The Network Performance Monitor charts, logs, alerts and reports about each and every transaction. It can keep track of every transaction such as logins, shopping carts, retrieved items from databases, downloads, checkouts, etc. It immediately warns and alerts the user about system related problems. It also can transfer data to applications like Microsoft Excel.
