There are a lot of great network monitoring tools available on the market. However, after reading through all of the sales details, you get to the point of wanting to buy and then find out that the software will only run on Windows or Windows Server. If you only have Linux servers and don’t want to mix the environment by adding on a Windows Server, then you have wasted time reading through a description of network monitors that you can’t install.
If you just want to keep your environment all Linux, you have three options when looking for a network monitor:
- A Linux-based network monitoring system
- A SaaS, cloud-located network monitoring system
- A network monitoring system that includes an operating system
In this review, we will pick examples from all three of these categories. However, most of the network monitoring tools on our list will install on a Linux server.
Here is our list of the eight best Linux Network Monitoring Tools:

What is Linux network monitoring?
Linux is an operating system for computers: endpoints or servers. Most network devices have their own firmware. So, when people talk about Linux network monitoring, they either mean monitoring a network where some or all of the connected computers run the Linux operating system or they mean running network monitoring software on a Linux host.
Networks are run on protocols that are operating system-independent. The most common form of a network system in the world is TCP/IP. This interfaces very easily with internet connections because the IP part of TCP/IP stands for Internet Protocol.
The majority of network monitoring systems use the Simple Network Management Protocol (SNMP) for their operating procedures. SNMP is not reliant on one particular operating system. All network devices already have one part of the SNMP system pre-installed on them when you buy them. This is the SNMP device agent. The only element missing from the monitoring system is the SNMP manager. So, network monitoring tools provide that the SNMP manager function. This enables them to gather all of the device statistics and traffic information that the device agents compile.
Top network monitoring tools interpret those device agent reports into time-series graphs and easy-to-read charts. Data collected on device statuses can be stored to produce performance analysis. This helps network managers plan capacity.
Another great feature of these SNMP-based network monitoring tools is that the device agent will send out a warning if they detect problems. These warnings, called traps, can be interpreted into alerts in the network monitoring tool. Alerts enable the IT support team to leave the monitor to watch over the network and assume that everything is OK unless notification to the contrary arises.
The only distinctive feature of a Linux network monitoring tool is that it can be run on or accessed from a Linux computer.
The best Linux network monitoring tools
Pay attention to the descriptions of these tools that we recommend because not all of them require an installation on a Linux computer.
Cloud computing is becoming very popular, so we have included a couple of SaaS network monitoring tools for those who don’t want to fill up your own server space with a network monitoring tool’s resource demands.
There is also an option that has a Linux operating system bundled into it, so you can install it on a new bare metal server without having to go through the process of installing Linux separately first.
The Best Linux Network Monitoring Tools
Our methodology for selecting a Linux network monitoring tool
We reviewed the market for network monitoring systems for Linux and analyzed tools based on the following criteria:

Linux network Monitoring FAQs
How do I monitor network traffic in Linux?
The easiest way to monitor network traffic from the command line in Linux is to use the netstat utility. Unfortunately, this system doesn’t automatically relaunch itself, so you should either write your own batch job to exploit this tool or buy a pre-written Linux-based network monitoring tool.
Is a command-line tool used for monitoring networks?
There are a number of network management tools built into the Linux operating system. However, all of them give you statistics on demand and not on an ongoing basis. You can’t sit and relaunch command line utilities all day, so monitoring the network in this way is impractical.
Is Wireshark a network monitoring tool?
Wireshark is in a category of network monitor that is called a traffic analyzer. This is one of the types of monitoring systems that you will need for your network. However, this is more appropriate for creating throughput analysis queries rather than system availability monitoring.
