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/

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'});

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
