Observium

NeDi and Observium or LibreNMS

NeDi and Observium are two¬†of my favourites network monitoring tools. I do like to deploy both, they complete each other and since they’re free there is no need to choose. The only problem with the use of two tools is the integration. Observium has a limitation with host discovery: a device can be discovered only by name and that name must be resolved to an IP via DNS or hosts file.
