Award-winning Network Monitor Now Supports 20,000+ Sensors with No Memory Limit

Burlington, MA and Nuremberg, Germany (October 30, 2012) - Paessler AG, the innovative network monitoring solutions specialist, today announced the launch of the first 64-bit version of its award-winning PRTG Network Monitor. Designed to meet high-performance monitoring needs for increasingly complex network environments, the new 64-bit version is now able to accommodate more than 20,000 sensors. The removal of any memory limit improves stability and performance in large installations. With a number of new sensor types added to the suite, the new 64-bit PRTG offers more advanced monitoring capabilities while still maintaining PRTG's trademark simple, user-friendly automated deployment system and user interface.

Like all 32-bit software, previous versions of PRTG had been limited to just three GB of RAM, supporting about 10,000 sensors on average. The newest version removes that cap, with a core server now shipped as both a 32-bit binary (for 32-bit Windows) and a 64-bit binary.  As a result, PRTG can now fully utilize the entire available memory on a host computer running a 64-bit Windows system. This enables PRTG to accommodate at least double the number of sensors, approximately 20,000.

For large networks, this expanded capability cuts the number of PRTG licenses or installations required to monitor the same, if not more, components in half, reducing the cost and further streamlining PRTG's already simple dashboard user interface.

"As part of our ongoing development and continuous rollout strategy, this release will serve as a base to further improve the capacity and performance of PRTG in the coming months," said Dirk Paessler, CEO Paessler AG. "We're already working to support even bigger installations, with a 50,000 sensor scenario fully operational in our test lab network. We are committed to further increasing PRTG's capabilities to meet growing customer demand."

About 200 sensor types to choose from

PRTG now offers an expanded range of sensors with about 200 different types for varying applications. Depending on the requirements, a close monitoring network's "spin" can be woven to provide detailed and targeted monitoring information. These precise sensor compilations can be managed easily, even in large networks.

Some of the new sensor types include:

  • Sensors for NetApp SANs to provide comprehensive monitoring of NetApp storage solutions;
  • Sensors for hardware monitoring via SNMP to monitor components on Windows and Linux systems;
  • MS Exchange Transport Queue Sensor for detailed monitoring of Exchange Server 2003, 2007 and 2010;
  • Port Range Sensor for multiple port monitoring using SNMP; and
  • WMI Custom String Sensor for monitoring SQL Server on Windows using WQL query.

Paessler's flagship PRTG Network Monitor has been recognized worldwide by leading IT industry publications, including the EMA RadarTM for Enterprise Network Management Systems: Q4 2012, the UK's IT PRO and Germany's Funkschau, for its rich feature set, ease of use and simple, cost-effective all-in licensing model.
