LanTopoLog 2

LanTopoLog 2 is a desktop application that discovers and draws the physical layout of a computer network. It uses SNMP to find switches and shows which device is plugged into each port, then keeps watching the network for faults.

What LanTopoLog 2 offers

• Topology discovery — builds a searchable, editable map that works with any switch model.
• Switch port mapping — links physical ports to the MAC and IP addresses of attached devices.
• Device monitoring — checks whether devices are up using ping and reports new devices.
• Traffic monitoring — tracks traffic, errors and dropped packets and warns when thresholds are passed.
• Alerts and reports — sends alarms by email, Telegram or syslog and exports reports to PDF or diagram files.
• Computer inventory — gathers machine details through WMI queries.
