To allow menu to open a link and show in thruk frame, we need to config allowed_frame_links in

OMD[demo@a36aee5c525e]:~/etc/thruk$ pwd
/omd/sites/demo/etc/thruk
OMD[demo@a36aee5c525e]:~/etc/thruk$ cat thruk_local.conf 
allowed_frame_links = https://192.168.112.174:5688/
OMD[demo@a36aee5c525e]:~/etc/thruk$ 

Create menu_local.conf under /etc/thruk/

OMD[demo@a36aee5c525e]:~/etc/thruk$ pwd
/omd/sites/demo/etc/thruk
OMD[demo@a36aee5c525e]:~/etc/thruk$ cat menu_local.conf 
do '/usr/share/thruk/menu.conf';

remove_item('Reports');
remove_item('General', 'Panorama View');
remove_item('System', 'Configuration');

add_section('name' => 'General');
  add_link('name' => 'Home', 'href' => '/thruk/main.html');
  add_link('name' => 'Logout', 'href' => $c->config->{'logout_link'}, 'target' => "_parent") if($c->stash->{'cookie_auth'});

  add_link('name' => 'Hosts',                 'href' => '/thruk/cgi-bin/status.cgi?hostgroup=all&style=hostdetail');
  add_link('name' => 'Services',              'href' => '/thruk/cgi-bin/status.cgi?host=all');
  add_search('name' => 'Quick Search:');

  add_link('name' => "Test submenu",  'href' => 'https://192.168.112.174:5688/demo/test3.html');

add_section('name' => 'System');
  add_link('name' => 'Configuration',     'href' => '/thruk/cgi-bin/config.cgi') if has_role('authorized_for_system_information', 'authorized_for_configuration_information');

}

Since the above test3.html and test2.html were refer from menu we can put those files in

[demo@669ee2143112 www]$ tree /omd/sites/demo/var/www/ 
/omd/sites/demo/var/www/
|-- test2.html
`-- test3.html

Problem of PING

After clone the image, we might have problem of normal user cannot ping. We can solve in 2 ways.

1. reinstall iputil-ping package

   [root@BU debian]# dpkg -l | grep ping
   ii  iputils-ping                              3:20180629-2+deb10u2                             armhf        Tools to test the reachability of network hosts
   [root@BU debian]# apt install --reinstall iputils-ping
   

2. chmod +s "$(which ping)" from this ​ref

before change

[root@BU debian]# ls -l /bin/ping
-rwxr-xr-x 1 root root 47704 Mar  9  2021 /bin/ping

after change

[root@BU debian]# chmod +s "$(which ping)"
[root@BU debian]# which ping
/bin/ping
[root@BU debian]# ls -l /bin/ping
-rwsr-sr-x 1 root root 47704 Mar  9  2021 /bin/ping
