LanTopoLog vs NetXMS

LanTopoLog discovers, maps and monitors physical network topology on a local network. It uses agentless SNMP discovery and presents a searchable, editable map; the maker says it works with any switch model. Its Switch Port Mapper links physical ports to attached devices’ MAC and IP addresses. Monitoring includes traffic, invalid packets and dropped packets, with threshold alerts sent by email, Telegram or Syslog. Reports export to PDF and Draw.io/Diagrams.net. Browser access and remote control are supported, but publishing requires an external web server. The product is listed for Linux, Windows and web use, though Linux has limited functionality. LanTopoLog 2 costs 50.00 USD once for one local network; the license covers up to three bound switches and cannot be renewed. Discovery may miss connections. After some time, the unregistered version disables web publishing, VLAN IDs, traffic charts and search, and shows demo data. A free plan and trial are listed.

NetXMS is an open-source monitoring solution for networks and infrastructure. It can run on premises or as a cloud platform. Automated discovery builds layer 2 and IP topology that can be displayed as connectivity maps, while supported protocols include SNMP, MQTT, EtherNet/IP, MODBUS-TCP, OPC UA, and HTTP/REST. Proxy agents and zones support distributed monitoring, including sites with unstable connections or overlapping IP ranges. NetXMS integrates with Grafana and supports notifications through email, SMS, Telegram, and Microsoft Teams; listed alert channels also include Slack. Its Java API supports actions available in the graphical interface and can be used for integrations and custom automation. Access rights can apply to all monitored devices, a group, or individual devices, including read-only access and alarm or command permissions. The homepage describes metric-level access controls and authenticated, encrypted communications. The free open-source plan is listed at free. Windows server binaries are limited to 250 nodes without a valid license, and requesting a free trial period requires contacting sales.
