About NMIS

NMIS is an Open Source Network Management System which performs multiple functions from the OSI Network Management Functional Areas. NMIS has evolved rapidly to meet the demands of highly available production environments and user demands.

NMIS has been developed continually since 1998 and remains open source. Version 9 represents the most recent major generational upgrade.

The distributed polling engine uses SNMP to collect availability and performance data for any SNMP capable device. A highly configurable and extensible GUI displays health and performance data focused on technical information, as well as high level reporting for executive reports.
