NetXMS is an open-source network and infrastructure monitoring and management solution, providing performance and availability monitoring with flexible event processing, alerting, reporting and graphing for all layers of IT infrastructure. It’s a solution for every type of device — it can monitor and manage your entire IT infrastructure — from network switches to apps — all in one place.

• Builds network topology and maps automatically
• Collects information via ARP caches, routing tables, LLDP, CDP, STP, switch forwarding databases
• Automatically updates peer information for all registered hosts and devices
• Provides searches for specific MAC or IP address and information about wireless access points and wireless clients
• Offers easy access to routing tables, MAC tables, and VLAN information
• Visualises IP routes
• Enables topology-based event correlations
• Supports all SNMP versions
• Has configurable routing change detection
• Provides a mechanism for handling vendor- or device-specific information and presenting it in a unified way
• Collects data via SSH
• Collects data via web services in XML, JSON and plain text format.

• Choose between the desktop or web-based version, or use both simultaneously
• Desktop version available for Windows, Max OS X, and Linux
• Offers graphical network maps and user-configurable dashboards
• Can be integrated with Grafana

• Provides agents for all popular platforms and operating systems — centralises configuration and upgrades, uses the minimum system resources, acts as proxy for other agents and SNMP devices if necessary, communicates in a firewall-friendly way, offers local cache for unstable connections
• Monitors log file contents
• Wide range of metrics out of the box:
  • network and I/O performance;
  • process, CPU, and memory consumption;
  • network services;
  • hardware sensors;
  • application-level metrics for various applications;
  • and many others
• File transfer capabilities built into the NetXMS agent
• Can be utilised for user support — a low-footprint application that presents users with preconfigured actions and basic information for helpdesk, configurable actions via NetXMS policies, screenshots and screencast

• Divides networks into zones with overlapping subnets and proxy agents for logical grouping or distributing data collection load
• Ensures automatic load balancing and failover with multiple proxy agents for each zone
• Continues to collect data in autonomous mode when the central management server is not available
• Receives syslog messages and SNMP traps from monitored devices to forward them to the central management server or local storage if the connection is down
• Eliminates the need to connect directly to each device in remote locations — a single TCP port open in either direction is enough for server-to-proxy-agent communication

• Allows for advanced automation and management
• “Hook” scripts can be called from many places within the system for custom processing
• Can be used for data transformation, complex thresholds, complex event processing rules, SNMP trap transformation, and many other purposes
• Uses easy-to-earn non-strict typed interpreted language
• Optimised for speed and low memory footprint so that a server can run hundreds of scripts simultaneously
• Each script runs inside its own VM with no access to anything outside the server process other than through well-defined APIs
• Additional security mechanisms are available to prevent unauthorised data access via scripts

• Full Java API allows users to do everything that can be done from UI
• Permits partial or complete replacement of UI
• Rest API provides access to collected data and NetXMS configuration
• Has modular agents and servers so that their functionality can be extended by writing additional modules (plugins)
• Python-based scripting language provides access to full Java API
• Built-in integration with helpdesk systems

• Offers an internal user database or integration with an external directory using LDAP (both can be used simultaneously)
• Supports authentication with passwords, X.509 certificates, smart cards, RADIUS or LDAP server
• Uses two-factor authentication with TOTP or one-time codes sent via SMS or instant message
• Encrypts all communications
• Enables fine-grained access control configuration
• Offers an extensive audit log with optional sending to an external system

• Offers flexible policy-based event processing
• Enables alarm creation and termination, internal script execution, command execution on a management server or on a remote host via a NetXMS agent and other configurable commands
• Supports notifications via email, MS Teams, Telegram, Slack, SMS via GSM modem or SMS gateway
• Offers support for problem escalation
• Has a flexible threshold system for data collection
• Configurable with templates for simplified management of large networks

• Translates metrics collected by NetXMS to business language.
• View vital SLA information at a glance.
• The status of the service is determined based on the status of monitored objects (servers, network devices, etc.) or metric thresholds.
• Calculate business service availability for the arbitrary time range.
• View detailed information about business service downtime, including start time, end time and cause.

Full installation information is available there.

We host public APT repository http://packages.netxms.org/ for all deb-based distributions (Debian, Ubuntu, Mint, Raspbian, etc.). Packages are signed, and you’ll need to install additional encryption key for signature verification.

1. Download and install netxms-release-latest.deb package, which contain source list file of the repository as well as signing key:

wget http://packages.netxms.org/netxms-release-latest.deb
sudo dpkg -i netxms-release-latest.deb
sudo apt-get update

2. Then you can install the required components, e.g. to install NetXMS server for use with PostgreSQL:

sudo apt-get install netxms-server netxms-dbdrv-pgsql

3. Amend database connection details in server configuration file (/etc/netxmsd.conf).

4. Initialize database schema.

nxdbmgr init

5. Start the NetXMS server

sudo systemctl start netxmsd

Installers for other platforms (Windows, Aix, Solaris...) are available on netxms.org.
