Hello,
does anyone of you have an idea why the Windows Service Detection is having issues with MSSQL$SQLEXPRESS? I suspect it’s because of the $, but I can’t remove that from the service. Every service without a $ gets added immediately.
Hi Dirk! 
Indeed there are some lists of illegal characters in checkmk. I don’t know which of these lists apply to your current problem, but here they are:
nagios_illegal_chars = "`;~!$%^&*|'\"<>?,="
cmc_illegal_chars = ";\t"
illegal_object_name_chars=`~!$%^&*|'"<>?,=
illegal_macro_output_chars=`~$&|'"<>
As far as I remember this means that you cannot have a service with one of these characters in its name. I think they simply get removed from the name (so $erv!ce gets ervce). At least that was the behaviour in earlier versions.
Cheers
Dirk
