You can also enable the service to start at boot time using: systemctl enable rvice yum install hiredis-devel Updated (thanks to Davide Lorenzetti for his comment): Let’s install the hiredis-devel package and start the redis server before starting ntopng. Let’s install the packages. We’ll have to accept Luca Deri’s GPG key: yum install ntopng ntopng-data Let’s create the ntop repository for the nightly builds: cat /etc//ntop.repo We’ll need to install the latest RPM packages: ntopng-data and ntopng. Ntop offers RPM packages for both CentOS/RHEL 6 and CentOS/RHEL 7 so it’s very easy to install.įirst of all we’re going to add the EPEL repository: yum install epel-release wget It supports sFlow so it will be great to use it with openvswitch and get some statistics. It has a lot of great features and I use it mainly to know quickly what kind of traffic is being generated in my network lab thanks to its web interface with summaries and rrd charts. Ntop NG is an extraordinary tool that helps you to know more about your network traffic. Thanks so much to Shashi and Steven for your comments.
