Installation

System Requirements
Version 4.x of PRTG Traffic Grapher requires the following basic system configuration:
• Windows 98/ME/2000/XP/2003
• Windows 2000/XP/2003 recommended
• 64 MB RAM (128 MB and more recommended)
• 6 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
• Opera 7.0 or later
• Mozilla 1.0 or later
• FireFox 1.0 or later
For SNMP Monitoring
The monitored device(s) must be equipped with SNMP (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.
