Step 3: Check the running status of the Netdata by using its default Port number

root@linuxhelp:~# netstat -tulnp | grep 19999
tcp        0      0 0.0.0.0:19999           0.0.0.0:*               LISTEN      53337/netdata       
tcp6       0      0 :::19999                :::*                    LISTEN      53337/netdata       

Step 4: Check the status of the Netdata service

root@linuxhelp:~# systemctl status netdata
