About
Use NetXMS 6.2 to watch network devices, servers, applications, and business services from one monitoring console, with events, alerts, performance data, reports, and graphs covering the full IT infrastructure. The desktop client connects to a NetXMS 6.2.x server and gives operators a centralized view of network and infrastructure health.
NetXMS combines automatic device discovery, generated network maps, zone assignment, multi-tenant operation, and API access with customizable thresholds, actions, and scripts. It supports authenticated, encrypted communications and access controls that can be applied to individual metrics, while monitoring can run on-premises or across remote and distributed networks. Service providers can use it for MSP, ISP, and WISP monitoring, while enterprises, schools, banks, telecommunications companies, production lines, payment switches, and ATM systems can apply it to specialized operational environments.
The system is designed as a modular, extensible enterprise platform and can monitor anything from network equipment through application and server layers. NetXMS 6.2 runs on Linux, is published by Raden Solutions, SIA, and uses the GNU General Public License version 2; its server and client architecture is the main component to account for before deployment.
Current version 6.2.5 adds a native MCP endpoint in the server, replacing the separate Java MCP server, and permits agent-side collection through Nagios-compatible plugins configured with ExternalCheck. It also introduces drivers for Aruba CX switches and Cisco Catalyst 9800 wireless controllers, while MQTT monitoring gains instance discovery, wildcard topics, parameterized extractor metrics, and payloads beyond the former 255-byte limit.
Requires Linux + Flatpak · Architecture: x86_64, aarch64
What's new in v6.2.5
- New network device drivers for Arista and Mellanox switches, and for Dell OS10 and Force10 (FTOS) switches
- New web API endpoints for pushing DCI values, getting the last value of table DCIs, and deleting objects; nodes' primary host name or IP address can be changed via web API
- Web API requests are handled by a thread pool (size is configurable, default 16) instead of a single thread
- Weather subagent: added Bright Sky provider (DWD open data for Germany)
- Unnecessary trailing zeros are removed from formatted fractional values
- Event processing policy editor opens large rule chains faster
- Data collection scripts are no longer restricted by Scripts.RestrictWriteAccess
- Windows installers bundle OpenSSL 3.5 LTS instead of 3.0.x, which has reached end of life

- #3619 (Scripts.RestrictWriteAccess blocks agent command execution in script-origin DCIs with no per-DCI override)

- #3630 (File manager subagent ignored read-only restriction for file permission change and move operations)
