# NetXMS — enterprise-grade monitoring



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.



## Features



### Network monitoring



* 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.



### User interface



* 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



### Server and workstation monitoring



* 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



### Distributed monitoring



* 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



### Built-in scripting engine 



* 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



### Integration



* 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



### Security



* 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



### Data and event processing



* 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



### Business services



* 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.



## Installation



Full installation information is available there: https://www.netxms.org/documentation/adminguide/installation.html#.



### Installing from deb repository



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



### Other options



Installers for other platforms (Windows, Aix, Solaris...) are available on netxms.org: https://www.netxms.org/download/.
