It can be configured to monitor and collect data from a wide variety of servers and network devices, and it provides service and performance monitoring of each object. Zabbix is a full-scale tool for network and system monitoring that combines several options in one web console. So here’s a list of the best network monitoring software: 1. Best bandwidth monitoring tool software#With functionality such as discovering network devices, monitoring network equipment and servers, identifying network trends, graphically presenting monitoring results, and even backing up switch configurations and routers, these network monitoring software tools will surely surprise you. Fortunately, the market now offers many good software solutions, both commercial and open source, for network monitoring. Vnstat supports many options, details about which can be found in the man page.If you don’t know the state of your network every second of the day, you’re like a blind pilot inevitably headed for disaster. It is not strictly a tool for monitoring the network in real time. Vnstat is more like a tool to get historic reports of how much bandwidth is used everyday or over the past month. Running vnstat without any options would simply show the total amount of data transfer that took place since the date the daemon is running. Next it can be used to generate a report of the history of network usage. ![]() It actually runs a background service/daemon and keeps recording the size of data transfer all the time. ![]() Vnstat is bit different from most of the other tools. Check the man page for more information 5. # ubuntu or debianīmon supports many options and is capable of producing reports in html format. CentOS users need to setup repoforge, since its not available in Epel. Best bandwidth monitoring tool install#Install Bmon – Ubuntu, Debian and Fedora users can install from default repos. The output also consists of a graph and a section with packet level details. Run IPTraf using the command below /usr/local/bin/iptrafīmon (Bandwidth Monitor) is a tool similar to nload that shows the traffic load over all the network interfaces on the system. Set PATH variable export PATH=$PATH:/usr/local/bin Here is a screenshot iptrafĪpt-get install iptraf iptraf-ng Build from source :įor Centos/RHEL (7.3, 7.4) yum install gcc tar git wget ncurses-devel ncurses makeįor Ubuntu (16.04, 17.10, 18.04) apt-get updateĪpt-get install gcc tar git wget libncurses5-dev libncurses5 makeīuild and install IPTraf cd /usr/local/src/iptraf-3.0.0-masterĬp /usr/include/netinet/if_tr.h /usr/include/linux/ It shows individual connections and the amount of data flowing between the hosts. Iptraf is an interactive and colorful IP Lan monitor. Install iftop – Ubuntu/Debian/Fedora users get it from default repos. The n option prevents iftop from resolving ip addresses to hostname, which causes additional network traffic of its own. But being based on the pcap library, iftop is able to filter the traffic and report bandwidth usage over selected host connections as specified by the filter. Iftop uses the pcap library to capture the packets moving in and out of the network adapter, and then sums up the size and count to find the total bandwidth under use.Īlthough iftop reports the bandwidth used by individual connections, it cannot report the process name/id involved in the particular socket connection. Iftop measures the data flowing through individual socket connections, and it works in a manner that is different from Nload. CentOS users need to get nload from Epel repositories. Installing Nload – Fedora and Ubuntu have got it in the default repos. So if you just need to take a quick look at the total bandwidth usage without details of individual processes, then nload will be handy. ![]() Easy and simple to use, and does not support many options. It also draws out a graph to indicate the same, the scale of which can be adjusted. Nload is a command line tool that allows users to monitor the incoming and outgoing traffic separately.
