You would get an interactive prompt for installing netdata, press Enter to begin the installation.

Welcome to netdata!
Nice to see you are giving it a try!

You are about to build and install netdata to your system.

It will be installed at these locations:

 - the daemon   at /usr/sbin/netdata
 - config files at /etc/netdata
 - web files    at /usr/share/netdata
 - plugins      at /usr/libexec/netdata
 - cache files  at /var/cache/netdata
 - log files    at /var/log/netdata
 - pid file     at /var/run

This installer allows you to change the installation path.
Press Control-C and run the same command with --help for help.

Press ENTER to build and install netdata to your system >

The above prompt would let you know where all your files will be placed. If you don’t want to install it in the default directories, you can run the installer like this: ./netdata-installer.sh –install /opt. This will install netdata in /opt/netdata.

At the end of the installation, you would get an output like below.


ok. NetData is installed and is running.

Hit http://localhost:19999/ from your browser.

To stop netdata, just kill it, with:

  killall netdata

To start it, just run it:

or KSM) available, but it is not currently enabled.

To enable it run:

echo 1 >/sys/kernel/mm/ksm/run
echo 1000 >/sys/kernel/mm/ksm/sleep_millisecs

If you enable it, you will save 20-60% of netdata memory.

Uninstall script generated: ./netdata-uninstaller.sh

Installer will start the netdata on completion of installation, verify that netdata is running using the following.

# netstat -antup | grep 19999
tcp6       0      0 :::19999                :::*                    LISTEN      5017/netdata

Accessing Netdata:

Configure the firewall to allow access to netdata web interface for the external machines, only valid if the firewalld is installed on your machine.

### CentOS 7 / RHEL 7 / CentOS 6 / RHEL 6 ###

# firewall-cmd --permanent --add-port=19999/tcp
# firewall-cmd --reload

Open up your web browser and navigate it to http://your-ip-address or  http://localhost:19999/. In my case, it is like
