PRTG Traffic Grapher 系統需求：

Version 6.x of PRTG Traffic Grapher requires the following basic system configuration:

• Windows 2000/XP/2003/Vista/2008 (32bit and 64bit)
• Running PRTG 6 on Windows 7 and 2008 R2 is not officially supported. It works except for packet sniffing. Please use PRTG 7 if you need packet sniffing on Win7 / 2008R2
• 256 MB RAM (512 MB and more recommended)
• 20 MB disk space for installation
• between 25kb and 300kb disk space per sensor per day for the monitoring data database
• TCP/IP Network Connection

To access the web interface one of the following web browsers is required (others may also work but have not been tested):

• Internet Explorer 6.0 or later
• FireFox 1.0 or later

For SNMP Monitoring: The monitored device(s) must be equipped with SNMP Version 1, 2c or 3 (or an SNMP software must be installed on the device). SNMP must be enabled on the device and the machine running PRTG must be allowed access to the SNMP interface.

For Netflow Monitoring: The device must be configured to send NetFlow data packets (NetFlow Version 5) to the machine running PRTG and a Netflow Collector must be set up in PRTG.

For Packet Sniffing: Only data packets passing the local machine’s network card can be analyzed. For cross-network monitoring in switched networks the use of switches with so-called “monitoring ports” is necessary. See the manual for detailed information.
