The best closed source Linux network monitoring tool

1. SolarWinds NetFlow Traffic Analyzer

In the closed source monitoring list, NetFlow Traffic Analyzer (NTA) provides great scalability for the number of network nodes you monitor. In the open source IT setup, it is worth noting that it works completely during the 30-day free trial period, so if your company is worried about whether it is worth the investment, SloarWinds can let you check it for free.

During the free period, once you understand how NTA works, due to interactive reasons, you can easily manipulate NTA and visual data display, if you already have a basic understanding of the Linux network, then you can use many useful non-expert features of NTA. This intuitive, interactive design will turn on your monitoring and analyzer network traffic without paying a lot of price.

NTA also provides visual bandwidth monitoring, allowing users to observe the ability of network points to see any unsolved problems. In addition, the extensibility of this tool helps you ensure that you adjust network elements without strong technical expertise.

NAT is very easy to use because of its performance monitoring console, and SolarWinds software is famous for providing a wide variety of code and search data. The performance monitoring panel helps you analyze your network flow. And simplify the operation.

2. Paessler PRTG Network Monitor

Paessler is a software developed by a German company that focuses on monitoring and data management. it is a closed-source monitoring tool, whose full name is PRTG network monitoring. it is lower in data visualization and graphics than SolarWinds NTA, but it is still a highly scalable product with customizable sensor options to meet the needs of companies of all sizes.

If your IT core needs to build robust architectures and sensors for each device, and to monitor the syslog entered by the Linux system, these sensors can focus on SNMP, LAN, cloud services, and various other metrics, and you can customize thresholds and alarm values as well as notifications.

With PRTG, you can configure monitoring collection to collect accurate data from a variety of sources, and the ability to customize sensors is surprisingly scalable. PRTG provides the fewest monitoring packages, up to 500 sensors and one service monitor, called PRTG500, up to the largest package called PRTG XL5, which includes an unlimited number of sensor installations and up to five server monitors

Like Solarwinds, Paessler also provides a complete program for a 30-day free trial period. The prices of Solarwinds and Paessler closed network monitoring tools vary according to the number of servers and sensors required by the system. Like all closed source system monitoring tools, please contact your chosen brand to determine which package is suitable for your purpose.

3. Nagios Network Analyzer

Nagios Network Analyzer can observe the traffic of specified ports and devices, just like PRTG, Nagios Network Analyzer contains monitoring data logs and network monitoring, which can help you ensure that the network and processes are running properly and without alarms. If abnormal activity is detected, Nagios Network Analyzer can automatically send the observed abnormal type of alarm to the IT monitoring center, and, like Solarwinds NetFlow Traffic, prompt easy-to-use color and graphic coding. And collect data and information from the server in a visual way.

Nagios is designed around Linux/Unix compatibility, so it can be used in parameters, and personalized panels help different IT experts interact with specific areas of the network, if you are more concerned about large and specific quality, then Network Analyzer may be a good choice.

In addition to a scaled-down version called Nagios Core, Nagios provides a free trial version of Network Analyzer, a free and popular open source data monitoring software, and the parameters of the free version of Network Analyzer can be set as required.

4. Zenoss Cloud

Zenoss is another recognized brand in the network monitoring industry, and for good reason, the company already offers a variety of competitive monitoring products. Zenoss is best known for its open source program Zenoss Core, which provides a combination of network monitoring and data analysis, but Zenoss has recently expanded to provide a more powerful, closed-source package Zenoss Cloud.

Zenoss Cloud is particularly useful in highly scalable network monitoring, providing visualization of network data and data logs, making it a useful tool for network functional operation and data security monitoring, and its machine learning method ensures that data is transmitted to central control in real time.

The biggest advantage of Zenoss Cloud is the function of 21st-century, which is rooted in the cloud-based architecture, so your network can be expanded rapidly, and the monitoring system will develop rapidly, which is very helpful for fast-spreading and fast-growing enterprises.

Like other closed-source tools in this list, Zenoss Cloud provides a free trial, and the parameters of the free version can be provided on request.

Ranking of open source Linux monitoring tools

Open source data monitoring is very useful for IT-savvy administrators who don't mind browsing the online community of software developers and constantly updating and developing public products to improve their defects, but open source monitoring deployment is more time-consuming and unfriendly than closed-source software, and there is a risk of malicious editing of the source code compared to closed-source software. But many IT experts find malleable free software attractive, especially when there is a strong online user community.

Here are some of the best open source network monitoring tools, each with its own advantages and disadvantages. I have found that the most useful open source tools are often those with a large user community that have helped you understand the software.

1. Lcinga 2

Image-20200906192539767

Lcinga 2 is a highly recommended modified version of lcinga. Recently, because of its scalability and real-time monitoring tools, lcinga2 is compatible with almost any operating system, and can measure a large network and provide a graphical interface. Although lcinga2, like other open source monitoring software, requires more skills to get started, it provides a highly interactive monitoring interface. Access monitoring is easy, and it is innovative for open source programs because it uses open source API technology to enable lcinga2 to monitor your network faster, resulting in data visualization that can be adjusted for input in real time.

2. OpenNMS

Image-20200907220526235

OpenNMS has existed since 1990, when it was called a management-oriented open source monitoring tool for enterprises and large networks. Since then, it has gained a strong online community through a simplified process of modification and improvement. OpenNMS is famous for its notification system, which provides real-time updates to central controls based on API monitoring results. OpenNMS is unique in that it focuses on the integration of industry standard management tools. Thus allowing southbound integration with other software programs, the alarm system is very comprehensive, with local java passing and external notification scripts.

3. Cacti

Image-20200907221025516

Cacti, which has been around for 20 years, is one of the most famous open source network monitoring software, allowing multiple users to monitor network devices and record network data, and provide privacy settings to determine which users can access which modules. It also uses the data logging and mapping software RRDTool to visualize data, and Cacti's age and established reputation give it a comprehensive online support system that includes templates for operating modified software on different devices.

4. ZABBIX

Image-20200907221702267

ZABBIX is compatible with Linux, Unix, Windows and Solaris System and is the first of various IT administrators. Like Cacti, Zabbix is mature monitoring software and has a large online community. ZABBIX provides clean Dashboard to detect changes in network activity, disk space and CPU load and keep track on your network. Thanks to SNMP, ICMP and TCP monitoring, zabbix can detect issues of concern to IT personnel, and It can use open source alarm software to notify the central controller of any network failure.

5. Pandora FMS

Image-20200907224650737

Pandora FMS stands for Pandora flexible monitoring system, which is indeed a flexible software. It provides a comprehensive network monitoring solution for almost any operating system, and includes many application integration and sensor components. The basic version provides a useful graphical analysis, while open source network monitoring tools do not always provide such graphical analysis, except for monitoring machines. Pandora FMS also includes the ability to integrate multiple applications simultaneously, as well as temperature monitoring and shutdown information, which is usually not found in open source monitoring software.

6. LibreNMS

Image-20200907225421702

LibreNMS shows its strength in its rapid response program, thanks to the high efficiency of open source API software. This kind of real-time monitoring is not uncommon in Linux network monitoring tools, but it makes LibreNMS particularly useful in providing automatic updates of network performance by extended multimedia alarm systems. LibreNMS combines this useful API with horizontally scalable network systems, enabling users to quickly expand node data monitored by central control. Without much trouble, because it is a relatively new program, founded in 2013, LibreNMS provides many other useful new features from the 21st century, such as integration with Android and IOS applications and virtual machine compatibility

7. Prometheus

Image-20200907230109611

Prometheus, which is designed to be compatible with Linux and Unix systems, provides a variety of basic network monitoring functions free of charge, due to integration with the Grafana graphics program. The built-in PromSQL function also provides customizable visualization of the interface. Prometheus is a relatively new software, so its community support mechanism may not be as powerful as other listed monitoring software (such as Cacti, zabbix), but it is used by many major corporate networks and may have an impact in the next few years.

8. EventSecutry Light

Image-20200907233526515

EventSecutry Light is the last open source tool in this list with the ability to monitor the network, and the rest of the programs are designed for small or personal servers, or for more centralized monitoring purposes. EventSecutry Light, designed for small businesses, is a quasi-system but effective tool for monitoring network packets and data logs, and has an alarm system to warn of abnormal activity in these two input areas. Like any open source monitoring software, EventSecutry Light has an online support community, but only by purchasing a more comprehensive closed-source version of EventSecutry combined network / data monitoring software can you get more reliable support.

9. Observium Community

Observium Community is a Linux network monitoring tool specially designed for small servers. It provides an online expert summary that sends patches and system software updates to users every six months. It is compatible with a variety of operating systems and uses standard SNMP network monitoring. Observium Community has impressive various monitoring functions, but it has a desire for a small scale, Observium Community administrator said. This program should not be used in large networks, and it can be run mainly on personal servers to manage network packets.

Observium Community provides a useful and important online support system, but only by purchasing a slightly more complex open source Observium Community package can you get more real-time updates and notifications about network activity.

10. Monitorix

Image-20200907234549276

Monitorix is a small server monitor designed specifically for Linux, but has since been extended to Unix-based operating systems. Although Monitorix runs only on small servers, it provides a number of monitoring features to update users based on system metrics. In the nearly 15 years since its inception, its functions have become more and more comprehensive, and now it can monitor everything from network functions to data consumption to disk drive temperature, thus ensuring that users can observe most of the functions that are critical to the proper operation of their network. Monitorix also includes simple but effective graphical pages for visual trend analysis.

11. Ganglia

Image-20200907235053357

Ganglia is a bit of a loner on this list because it has a unique use compared to some other Linux network monitoring tools. Its name comes from a term in neuroscience that refers to neural networks linked to a large number of cell bodies, which is what Ganglia simulates in computer networks. It has been around since 2000 and provides an extensive history of online user contributions, which is a must for any good open source program. But the biggest difference is that the cost of each node is very low, so it can be highly scalable in networks with hundreds or even thousands of different units.

Although Ganglia does not provide some of the more complex data alarm mechanisms than some other open source programs, many large organizations find it a useful tool for monitoring a large number of different units. And, like several other open source tools, Ganglia uses RRDTool software to provide useful data visualization.

12. Htop

Image-20200907235235069

In this list, we will begin to review less complex programs to accurately and reliably monitor the use of small networks. Htop (H stands for designer's name, Hisham) does not include graphical analysis software, but it provides flexible monitoring programs that can be installed on Linux and Unix-based systems. Htop may not be the most visually pleasing monitoring software, and its interface looks more like an old-fashioned computer from an 1980s movie, but it is useful for providing real-time updates of network activity and storage capacity in pure English. In addition, if you do not want to parse dozens of monitoring updates, htop's interface will use an intuitive color-coding system

13. BWM-NG

Image-20200907235429947

The next monitoring tool on our list is one of the simplest, most straightforward, but surprisingly flexible Linux monitoring solutions. BWM-NG (on behalf of the next generation bandwidth monitor) does not provide any graphics updates or fine color coding, but it is a useful program for small network Linux experts who are primarily interested in bandwidth monitoring.

The program is a modern redesign of the previous BWM and is still in the testing stage, which means that you may have to use Linux skills to solve inefficient problems. But BWM-NG provides an active online user community to help you achieve your goals and multiservice compatibility with Linux and Windows, which is an unusual situation for small network open source monitoring programs.

14. EtherApe

Image-20200907235608988

EtherApe is a network monitoring software compatible with Linux / Unix system, which can show the advantages of graphics. For IT experts who want to monitor small networks without a large number of numbers and obscure scripts, EtherApe provides an elaborate graphical component to visualize network data. Like some other open source tools, it reads packets from your network and files and supports common devices such as WLAN,FDDI,ISDN. It is modeled with the more outdated monitoring software etherman. EtherApe has been around for no longer than some of the other programs in this list, so its online community and web page updates may be less reliable.

15. Ibmonitor

Image-20200907235753123

Ibmonitor is a terminal-based application, and because of some other monitoring tools, it is not easy to convert to a new control unit, but if you are using an older computer, ibmonitor is used to monitor a variety of network activities with an interface that you can personalize to try and a real tool. If your goal is to monitor bandwidth usage and other basic Linux network updates, ibmonitor can provide a simple analysis of the network and summarize information about your entire network. Like HTOP, it uses color-coded text, and you can find the interpretation functions of a variety of online forums.

How to choose Linux monitoring tools

For IT experts responsible for ensuring the health of Linux systems, the implementation of Linux network monitoring tools is an essential step. There are dozens of network monitoring tools on the market for Linux, including free open source and paid closed source software, which is why choosing between them can be overwhelming. Understanding the key to Linux monitoring tools is the key to narrowing down the scope, and it is important to understand the differences between the various tools, even if they seem small.

I hope my list provides you with a good basis to start weighing the pros and cons. Here, I will break down the main considerations of your decision, including the budget, the level of support required, and the size and scalability of the network.

Closed source vs open source

Your first decision is whether to use closed source or open source software. Closed source software can be expensive, but if you are managing a wide range of networks and do not have time to troubleshoot through online forums, the professional customer support provided by closed source software is well worth your initial fee.

Closed-source software also has the advantage of simplified usability, usually providing fast graphical analysis and interfaces designed for busy IT professionals to manage large amounts of data. Closed source code also has the advantage of increasing security protection. Although open source software is difficult to hack into, and it usually does not cause security problems, the public availability of its code seems too risky for companies with highly sensitive information.

Expandability

When choosing a network monitoring tool, be sure to consider the size and scalability of the program. Some open source software is designed specifically for small networks, so if you are running a large corporate network with multiple nodes, you should not consider using it.

For example, Observium community is an excellent monitoring tool, but it is mainly used in small networks. On the other hand, tools such as SolarWinds NetFlow traffic analyzer or Paessler PRTG network monitor can be effectively used by large corporate networks that need to manage a large number of nodes or expand the number of users.

You need to weigh scalability and other considerations. Open source programs like Ganglia are highly scalable, which is characteristic of Ganglia, but it may not provide the simple visual interface or automatic data analysis capabilities that some other tools can provide. Software like Ganglia, with low overhead per node, may be useful for researchers who want to monitor the basics of large network operations. But for IT experts who monitor the networks of large companies, other programs may be more appropriate. More comprehensive monitoring tools such as SolarWinds NTA or Nagios Network Analyzer may need their real-time graphical analysis and alarm systems more.

Support

Other important considerations include the level of support you are looking for and what you want to monitor. When you study open source programs, please visit the online user community, because anyone can use open source software, so it is almost certain that paid customer support teams will not provide services for the software. If you are following the source route, it may be better to have a user community with a monitoring tool. If this factor is important to you, consider using active user groups (such as OpenNMS) or user communities with e-mail updates (such as Observium community).

Or, you may want to use open source tools to focus on specific monitoring areas. For example, if you focus on bandwidth monitoring, BWM-NG might be worth a look. If you are interested in small web visual maps, please check out EtherApe. If you need a quick alarm system, you can choose EventSentry Light.

Expenses

Before purchasing closed-source tools, you need to consider their indirect costs and benefits to the company. For major business networks, the advantages offered by closed-source monitoring tools may be worth investing in. If security guarantees, simplified customer support systems, and the multi-purpose capabilities of closed source tools meet your needs, I highly recommend SolarWinds NetFlow Traffic Analyzer.

SolarWinds NTA contains all the necessary components of an effective closed source monitoring tool-security, reliability, customer service and flexibility. It provides network analysis, bandwidth monitoring, security monitoring of suspicious activity, and periodic alerts to keep you informed of any important network activity. Known for its high-end visual analysis, SolarWinds provides an easy-to-digest Web-based interface that contains graphics and statistical information about the network, and has a dashboard to track all moving parts.

Another advantage of SolarWinds NTA over other closed source tools is that it can be integrated with other advanced software. SolarWinds provides many other tools for data logging and security monitoring, such as user equipment tracker, network configuration manager, and network performance monitor. For comprehensive IT management, SolarWinds provides an opportunity to extend your monitoring tools to a more powerful network analytics program.

The best Linux network monitoring software

Image-20200908000629223

Before you choose the Linux network monitoring tool, you need to have a comprehensive understanding of your company's needs. Some open source tools may have expertise that you may not find useful, while others may be just right for you. If you are an IT expert and have enough time and expertise to build (and track) open source programs, you may prefer to use the free Linux network management tools.

If you need to close the reliability and toolkit of the source software, you can decide that it is worth the investment. And, if you're not sure, most closed source tools offer free trials. Some software providers (such as SolarWinds and Paessler) even allow a full-featured free trial for 30 days, so you can see what closed-source software can provide first. I still recommend that you consider NetFlow Traffic Analyzer as the most comprehensive Linux monitoring tool on the market.
