NetXMS
Riga, Latvia
What it is
NetXMS is an open-source solution for monitoring networks and infrastructure, with on-premises and cloud deployment options. Its automatic discovery builds layer 2 and IP topology that can be shown in connectivity maps. Supported protocols include SNMP, MQTT, EtherNet/IP, MODBUS-TCP, OPC UA, and HTTP/REST. Proxy agents and zones support monitoring across distributed locations, including sites with unstable connections or overlapping IP ranges. NetXMS integrates with Grafana and supports notifications through email, SMS, Telegram, and Microsoft Teams; the listed alert channels also include Slack. The Java API exposes actions available in the graphical interface and can support integrations and custom automation. Administrators can set permissions for all monitored devices, groups, or individual devices, including read-only access and alarm or command actions. The homepage describes metric-level access controls and encrypted, authenticated communications. The free open-source plan costs nothing. Windows server binaries are limited to 250 nodes without a valid license, and a free trial period must be requested from sales.
