Comment # 6 on bug 1172228 from Robert Munteanu

FWIW, 15.3 has the same problem. Switching to the server:monitoring repository
( although I am really hesitant to do that in a production setting ) does not
seem to work due to missing dependencies:

$ zypper dup -r server_monitoring --allow-vendor-change

 Solution 1: Following actions will be done:
  keep obsolete php-Icinga-2.7.4-bp153.1.11.noarch
  keep obsolete icingaweb2-vendor-zf1-2.7.4-bp153.1.11.noarch
  keep obsolete icingaweb2-common-2.7.4-bp153.1.11.noarch
 Solution 2: deinstallation of php-Icinga-2.7.4-bp153.1.11.noarch
 Solution 3: break php-Icinga-2.8.4-lp153.82.1.noarch by ignoring some of its
dependencies
