netwonk

Netwonk is a network monitoring package for Cisco equipment. It also supports some Palo Alto firewalls, and can be extended to other hardware. It is written in Perl and runs in linux/unix.
The netwonk project includes a collection of scripts, the netpeek web package, and configuration for all databases and tables on an integrated mariadb/mysql server.
A normal netwonk installation consist of separate script, web and database servers. This works nicely with a trio of VMs. In a small installation, all three functionalities could work on one server, though that has not been tested.
