An advanced, easy-to-use monitoring solution for your entire network. The software's features include: up/downtime monitoring, traffic and usage monitoring, packet sniffing, in-depth analysis and concise reporting. A user-friendly web-based interface allows users to quickly configure the network devices and sensors they wish to monitor. All common methods for network usage data acquisition are supported: SNMP and WMI, Packet Sniffing, and NetFlow. PRTG Network Monitor includes more than 30 sensor types for all common network services (e.g. PING, HTTP, SMTP, POP3, FTP, etc.), allowing users to monitor networks for speed and failures. As soon as an outage occurs, alerts are sent via email, SMS, pager messages and other means. Request times and downtimes are recorded in an internal database, making it easy to compile performance, downtime and SLA reports. PRTG Network Monitor's Freeware Edition is completely free for personal and commercial use. The Commercial Editions are required if you want to monitor more than ten sensors.
