PHP Server Monitor is a script that checks whether the servers/Websites on your list are running. Each server has its own notification settings. Notifications are made via email or text messages. Using the Web-based interface, you can add servers and manage users for each server.
Switchmap is a Perl program that creates HTML pages that show information about a set of Cisco Ethernet switches. It uses SNMP to gather data from a list of switches, given the list of IP addresses and names. The output pages show, for each port, the status, duplex, VLAN, speed, and what's connected to the port (MAC address, IP address, DNS name). The pages help network engineers quickly see switch information.
