Thank you for using the Freeware Edition of PRTG Network Monitor
PRTG Network Monitor covers all aspects of network monitoring: uptime monitoring, traffic and bandwidth usage monitoring combined with concise reporting and analysis features - one clear and simple solution for your entire network.
The software runs 24/7 on a Windows-based machine within your network, recording bandwidth and network usage parameters. Recorded data is stored in a database for historic reports. The easy to use web-based user interface allows to configure the devices and sensors that you want to monitor. You can create usage reports and provide colleagues and customers access to graphs and tables.
All common methods for network usage data acquisition are supported: SNMP and WMI, Packet Sniffing, and NetFlow. For performance and availability monitoring PRTG Network Monitor also includes more than 120 sensor types for all common network services (e.g. Ping, HTTP, SMTP, POP3, FTP, etc.), allowing to monitor your network systems for speed and failures. As soon as outages occur the software will alert you by sending emails, SMS, pager messages and other notifications. Request times and downtimes are constantly recorded in the database and you can compile performance downtime and SLA reports at any given time.
