Introduction

Requirements and planning

Please read the Requirements and configuration topics before you start monitoring your network. These topics describe how to configure hosts and nVision to get all the information you need.

Discovering the network

nVision has a built-in very advanced automatic network scanner allowing you to not only discover all hosts in your network, but also it can discover all routers and go through them to scan all neighboring networks. It discovers all hosts and services running on them, like: HTTP, FTP, mail, database servers, etc.

You can add as many networks to the Atlas as you need. When adding a network, it will be scanned for hosts so first you have to go through the network discovery wizard to define scanning options.

When the discovery process is finished, the program will create a network map or a set of maps for all discovered IP networks. The networks will be created as a tree. This tree shows network dependencies between them.

For more information about network discovery refer to Discovering the network topic.

Monitoring hosts

nVision can monitor network services, system and SNMP counters. It not only monitors them, but also logs all the information and allows viewing historical data for reporting purposes.

For more information about network monitoring refer to Monitoring topic.

Host status

Host status in nVision is such an important idea that we dedicated it separate topic for it: Host status concept. You should definitely read it to fully understand how nVision presents host status.
