June 2009: Birger was off making monitoring magic at one of our clients implementing an integrated Nagios, NETWAYSGrapher and NagVis environment from scratch. Working hand in hand with the client (anonymous), Birger applied nmap, SNMP and Cisco Discovery Protocol (cdp neighbours) to enable automatic generation of configurations including parent-child relationships and host groups (vtp-domain).
Further developing and customizing check_interface_table.pl, Birger took on the client’s 1,500 Cisco switches and 10,000 ports to enable traffic graphs for each interface, which can be selected using regular expressions.
In so doing, he simultaneously released check_interface_table_v2.pl for all to download under GPL.
