PRTG Traffic Grapher  網路流量監控軟體

PRTG Traffic Grapher

是簡單好用的視窗軟體，可監控並分類每一時間區間的流量使用率。它使用即時讀取和長期流量的趨勢變化為他的網路設備提供系統的管理。最常使用的是流量控管，也可以監控許多方面譬如記憶體及ＣＰＵ的有效使用。

監控幫助你最佳化你的網路速度

With PRTG Traffic Grapher you will receive bandwidth and network usage data that helps to optimize the efficiency of your network. Understanding bandwidth and resource consumption is the key to better network management:
　

避免流量和服務平台的衝突

 ● Avoid bandwidth and server performance bottlenecks
 ● Find out what applications or what servers use up your bandwidth
 ● Deliver better quality of service to your users by being proactive
 ● Reduce costs by buying bandwidth and hardware according to actual load
　

網路和流量監控的作業模式

PRTG Traffic Grapher is running on a Windows machine in your network for 24 hours every day and constantly records the network usage parameters. The recorded data is stored in an internal database for later reference.

This sample graph shows the usage of a leased line over various time periods:

Using an easy to use Windows interface you can configure the monitored sensors as well as create usage reports. For remote access PRTG Traffic Grapher comes with a built-in web server to provide access to graphs and tables.

All common methods for network usage data acquisition are supported:

SNMP: Simple Network Management Protocol is the basic method of gathering bandwidth and network usage data. It can be used to monitor bandwidth usage of routers and switches port-by-port as well as device readings like memory, CPU load etc.

Packet Sniffing: With its built-in Packet Sniffer PRTG can inspect all network data packets passing the network card to calculate the bandwidth usage.

NetFlow: The NetFlow protocol is supported by most Cisco routers to measure bandwidth usage. Although being the most complex type to set up it is also the most powerful method suitable for high traffic networks.
For Packet Sniffer and NetFlow based monitoring PRTG can optionally calculate the bandwidth per IP address or port, e.g. to show the current Top Talkers, Top Connections and Top Protocols of your network.
