GroundWork Open Source is moving higher up the food chain. To that end, the company launched at the start of the Open Source Business Conference in San Francisco its first enterprise edition and a significant upgrade of its networking monitoring platform that is more scalable and extensible. GroundWork Monitor 5.2's monitoring capacity has improved by a factor of five and the software can support more than 10,000 servers, the company said. The new enterprise edition boasts a Nagios-based Event Broker that can monitor thousands of devices and systems and an event console that can handle high volumes of messages. GroundWork Monitor Enterprise joins existing GroundWork Monitor Professional and the free, downloadable GroundWork Monitor Community Edition. The GroundWork Monitor Enterprise is an alternative to proprietary monitoring modules in HP OpenView, IBM Tivoli, CA Unicenter and BMC Patrol but also can integrate seamlessly with those systems as well as other management systems based on Windows and AIX. GroundWork is a proprietary software solution based on the Nagios open source alerting and monitoring project. Executives say they have worked closely with Nagios consulting firms such as Nagios Enterprise to grow its market share. “We’re seeing enterprise growing faster for us. Enterprise customers see more and more of a great price advantage with what we’re doing and those customers tend to be stickier," said David Dennis, a senior director of product marketing at Groundwork. "The open source option is turning out to be stronger with the big boys than SMB.” Version 5.2 also features new enterprise performance reports and view-only dashboards as well as enhanced automated installation, discovery and configuration capabilities.
