Monitoring Tools

Stay on Top of Your Network Using Paessler’s Monitoring Tools

PRTG Network Monitor is Paessler's powerful network monitoring tool. It monitors the uptime of network devices, tracks bandwidth usage, and helps you to improve network performance and to control service level agreements.

Features of the Monitoring Tools

  • Bandwidth Monitoring: using SNMP, packet sniffing, and NetFlow, the networking software gives you a complete overview of the traffic flowing through your network. The bandwidth monitoring tools enable you to analyze and classify network traffic broken down by port, IP address, protocol, or other parameters.
  • Availability Monitoring: the network management application uses an advanced PING test to check whether your network devices and websites can be reached.
  • Performance Monitoring: the monitoring tools can also check network speed and network load, CPU and memory load. This shows you what loads your network is subject to and alerts you to performance issues.
  • Network Analysis and Troubleshooting: continuous network monitoring helps you to detect bottlenecks and possible failures at an early stage and troubleshoot them before they cause downtimes.
  • VoIP Traffic Monitoring: PRTG includes a range of sophisticated VoIP monitoring tools: using either the QoS sensor, or the IP-SLA sensor (in case you have IP-SLA enabled hardware), you can check factors such as packet loss, round-trip-time (RTT), and packet delay variation.
  • Windows Monitoring: thanks to the monitoring tools' WMI support, you can monitor all kinds of Windows system information: free disk space, file and folder changes, CPU utilization, file size, etc. However, PRTG can also be used to monitor Linux and Unix servers and workstations.
