It looks like that the inventory function has not created the correct parameters for your discovered services.
Can you make a test on the command line please.
cmk --debug -vvII hostname
after this was done without error can you have a look at the created autocheck file in
~/var/check_mk/autochecks/hostname.mk
Inside this file you should see in the line with the “heartbeat_crm” check also a parameter entry.
Is this so?
