Who's it for?

The PRTG Network Monitor Software provides network administrators with an easy to use device monitoring application that is scalable to networks of all sizes. This tool can help minimize downtime for critical systems by providing administrators with early warnings of outages, rather than having to wait for user complaints or trouble tickets.

What problem does it solve?

PRTG Network Monitor monitors system availability using a variety of methods from simple ping through SNMP and WMI protocols to specific tasks such as HTTP, DNS, and Remote Desktop availability using various sensors. Using specific sensors for specific machines, an administrator can monitor service availability - including Exchange and SQL - and be notified instantly of problems. Also, PRTG comes with some bandwidth monitoring sensors, so you can ensure that malware designed to do DoS, "phone home", and other overload activities are not operating on your network.

Standout features

  • Lightweight: PRTG monitoring uses very little active memory and CPU time to monitor a small network of devices. Also, with a small hard drive footprint per sensor, many systems will be able to run this application.
  • Easy to Use: With a simple startup wizard, PRTG can have you up and running with several types of sensors in minutes. PRTG can be configured to scan a subnet on a regular basis to look for additional devices.
  • Various interfaces: With Browser-based, Windows GUI, and iPhone interfaces available, the PRTG GUI is accessible on any device, from anywhere.

What's wrong

  • Maps: While PRTG allows you to create maps of your network, it doesn't seem to automatically link devices together. You must instead have an image of you network topology to use as a background for the map.

Competitive products

Bottom line for business

All business networks have critical systems that can seriously harm productivity, output, and revenue if they experience significant outages. With the PRTG Network Monitor, network administrators can monitor systems for trouble, hopefully before it happens, and begin diagnosing system problems, before the users open trouble tickets.
