It is very important for network administrators to monitor network performance issues, and network monitoring tools can help enterprises track and solve these problems. However, implementing and maintaining network monitoring solutions can be expensive. Fortunately, there are many free and open source solutions on the market, and network administrators need some time and patience to choose carefully.

These open source tools are released under an open source license and can be considered if companies want to reduce costs. It should be noted that some may not suit your needs because of the expertise required by many open source tools. Therefore, some of the main features of each open source tool are listed below so that you can understand the advantages of each solution.

Angry IP Scanner

Angry IP Scanner is an open source network and IP scanning tool. The software scans IP addresses connected to the network and checks the status and availability of each device. Angry IP Scanner uses a multithreaded approach to monitor by creating a separate thread for each scanned IP address; this increases the speed of tool IP monitoring. The tool also supports NetBIOS information, IP address range, Web server detection and customizable opening tools.

Cacti

Cacti is an open source network monitoring tool based on RRDTool data recording and graphics system. The tool uses network polling and data collection features to collect device information on networks of any size. This includes designing custom scripts for data collection and the ability to support SNMP polling. It then displays this information in easy-to-understand graphs that can be arranged according to the hierarchy that best suits the business.

Checkmk

Checkmk is an open source infrastructure and application monitoring tool, as well as network monitoring capabilities. For network monitoring, Checkmk can discover and monitor switches and routers, wireless networks and firewalls; the software supports integration with multiple network hardware vendors. The solution uses a rule-based concept to configure network and device monitoring, allowing enterprises to configure the entire network to monitor specific metrics.

Icinga

Icinga is an open source network monitoring tool that measures network availability and performance. Through the Web interface, enterprises can observe hosts and applications across the entire network infrastructure. The tool is natively extensible and can be easily configured for a variety of devices. There are also Icinga modules for specific monitoring functions, such as the vSphere cloud environment for monitoring VMWare and business process modeling.

LibreNMS

LibreNMS is an open source network monitoring system that uses a variety of network protocols to observe every device in the network. LibreNMS API can retrieve, manage and plot the data it collects, and supports horizontal scaling to enhance its network monitoring capabilities. The tool has a flexible alarm system that can be tailored to the methods of the enterprise to communicate with you. They also provide native iOS and Android applications.

Nagios Core

Nagios Core is an open source network monitoring tool designed to serve as the basis for other monitoring and alarm software provided by Nagios. It is primarily a performance checking tool that schedules and performs network performance checks throughout the infrastructure. As a performance check event handler used by other Nagios software, Nagios Core can also extend its functionality through independent attachments through Naigos Exchange.

NetXMS

NetXMS is an open source infrastructure and network monitoring and management solution. The tool provides flexible event handling, reporting, and visualization graphics for all layers of the IT infrastructure. For network monitoring, NetXMS provides automatic layer 2 and layer 3 discovery and full SMNPv3 support. The program also includes active and passive discovery, combining scanning probes with information collection functions.

Ntopng

Ntopng is an open source network traffic analysis tool with network monitoring function. The tool is a network traffic probe that classifies network traffic into different standards, including IP addresses and throughput. By characterizing network traffic, enterprises can easily determine the different network statistics that affect the network. Although the community version of ntopng is open source, professional and enterprise versions are also available.

Opmantek NMIS

Opmantek NMIS is an open source network management solution for scalable network performance and device status monitoring. NMIS classifies network events according to business impact. NMIS is included in Opmantek's NMIS Professional package, which also includes opCharts for performance charting through customizable dashboards and opReports to analyze performance data and generate reports on this data.

Pandora FMS

Pandora FMS is an open source monitoring tool that helps enterprises observe the entire IT infrastructure. It not only has the function of network monitoring, but also has Windows and Unix servers and virtual interfaces. For networks, Pandora FMS includes functions such as ICMP polling, SNMP support, network delay monitoring and system overload. You can also install an agent on the device to observe factors such as device temperature and log files.

Prometheus

Prometheus is an open source monitoring solution focused on data collection and analysis. It allows users to set up network monitoring functions using the native toolset. The tool can use SNMP ping to collect information on the device and check network bandwidth usage and other functions from a device perspective. The PromQL system analyzes the data and allows the program to generate graphics, tables, and other visual effects on the system it monitors.

Wireshark

Wireshark is an open source network protocol analyzer with real-time network data capture and analysis functions. The tool performs in-depth checks on several different network protocols to determine multiple levels of network performance. Wireshark also allows users to capture packets and analyze them, even when the network is offline. Data captured by Wireshark can be stored in a variety of common or shared file formats, allowing other tools to help interpret data on the network.

ZABBIX

Zabbix is an open source suite of monitoring tools, including network monitoring. Zabbix's network monitoring capabilities include performance metrics such as bandwidth usage, packet loss, and CPU/ memory utilization. It can also detect network nodes and connection health problems by checking devices in a critical state. Zabbix can alert you when the hardware function slows down (the fan speed of the network device is slow) or does not respond to the SNMP check.
