If you liked GreatNMS, please note : for additional price, you can OEM it and sell as YOUR network management solution . You can make your network products to be managed by GreatNMS (this includes customized front panel view of your devices). You may have noticed that GreatNMS has more generic features than expensive so called "industry standard" systems used for managing enterprise and carrier/service provider networks. When adding a device support to the list of devices managed by GreatNMS, I will usually ask you for the remote access to the device and management protocol specs. It may be simply SNMP mib, but it can be also any protocol (including proprietary protocols). Sometimes it is also good to receive a picture of your device, so the NMS could present a nice interactive front panel view (end customers appreciate such views)
GreatNMS server is a native Win32 application, however I also have GreatNMSJ, which is GreatNMS Java version. GreatNMSJ can run on any Linux/Unix OS.
Additionally I can develop EMS (element management system) GUI which is embedded in your network device and can be invoked remotely via any Web Browser (no software installation is required on client computers).
GreatNMS is created and supported by ONE dedicated software professional. I am located in the Greater Los Angeles Area, California, USA.
