I am trying to configure meaningful notifications based on hostnames (through WATO). However I am not sure, if the hostname fields in “Match only the following hosts” and “Exclude the following hosts” only accept full host names or also placeholders (“pc-", “pc-???”) or even full regular expressions ("pc-.”, “pc-…”). I was not able to find this information in the manual. Please don’t hesitate to refer me to RTFM, should I have overlooked it
We are currently using the 1.6.0 enterprise edition.
The hostname field cannot be a regular expression or a name with placeholders.
This must be a valid hostname.
For such groups of hosts i would use the host tags / labels or hostgroups.
However this could also have been an omission in the documentation, as placeholders and/or regexes are supported in so many other locations in check_mk
I can’t use hostgroups in the concrete case, as there is only a “Match Host Groups” but no “Exclude Host Groups” (unfortunately, that would be very handy to have… ).
We currently don’t actively use tags. I’ll have to check how to use them and how to assign tags to servers. Thanks for the hint
I am confident you will find a solution using the input from @andreas-doehler.
However, I am discussing your input on clarifying how to use that field internally.
