Device42 vs NetXMS

Device42 provides agentless discovery, asset management, and dependency mapping for data center, cloud, and hybrid IT environments. Its scope includes CMDB, DCIM, ITAM, IPAM, password management, and application dependency mapping, in a self-hosted deployment. It can discover network devices through SNMP and cloud resources across AWS, Azure, Google Cloud, Oracle Cloud, and OpenStack.

For data centers, its visual models cover buildings, rooms, racks, cabling, and patch panels, with power and temperature heat maps. Core includes discovery, inventory and asset management, integrations, REST APIs and webhooks, warranty and SSL certificate management, cable and password management, and IPAM. Device42 also tracks software licenses, contracts, and barcodes, and lists more than 30 integrations. Licenses count devices with IP addresses; non-IP assets do not count, and user seats are unlimited. If the device limit is exceeded, the software keeps running but stops collecting additional information until the license is increased. Pricing is available on request, and a free trial is offered.

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.
