Q:

why Ubuntu Firewall not showing verbose?

Even Ubuntu Firewall in running mode , I am not getting the data. may I know why ?   
root@ubuntu:~# sudo ufw status numbered
Status: inactive
root@ubuntu:~# service ufw start
start: Job is already running: ufw
root@ubuntu:~# sudo ufw status numbered
Status: inactive
root@ubuntu:~# sudo ufw status verbose
Status: inactive
root@ubuntu:~# 

A:

You need to enable the firewall using
sudo ufw enable

After you enable, sudo ufw status verbose should show you the following:
Status: active
Logging: on (low)
Default: deny (incoming), allow (outgoing)
New profiles: skip

To check more options use, ufw help
