NetXploreIt server consists of four main components: Application, Discovery database, Syslog database, and a Syslog listener. The above figure represents those components and their links with each other, the network, and the clients. Below are descriptions of functionality and operations of each component.

Application: runs the main application logic for:

1. Discovery of device information (using SNMP protocol).
2. Build up of network topology.
3. Storing of device inventory and network topology in the “Discovery database”.
4. Collecting device configurations.
5. Managing and authenticating user accounts.
6. Responding to clients requests by querying the databases.

Discovery Database: Stores device inventory and network topology, as well as user accounts information.

Syslog Database: Stores network devices’ Syslog messages, and pre-indexes data for fast query response.

Syslog Listener: listen for syslog messages, parses the messages into a unified format, and publish parsed messages into the syslog database.
