The values of the check_command and check_command_expanded livestatus columns were not exactly the same in Microcore as in Nagios:

Microcore:

OMD[stable]:~$ lq "GET services\nFilter: description = Events ServiceSystem\nColumns: check_command"
check_mk_active-mkevents!$HOSTNAME$/$HOSTADDRESS$ '^(?!Service|System).*$'

Nagios:

OMD[stable]:~$ lq "GET services\nFilter: description = Events ServiceSystem\nColumns: check_command"
check_mk_active-mkevents!$HOSTNAME$/$HOSTADDRESS$ '^(?\!Service|System).*$'

The Microcore has now been changed to work exactly like the Nagios core.
