Re: Check_MK Werk 0973: Renaming of hosts via WATO

Hi, a better way to tackle renaming issues is to *never* make use of user defined names in rules, groups, folders, etc. and to do it as follows: * For each new entity for which a user chooses a name, like hosts, groups, folders, etc., also generate a permanent UUID. Then add an entry to a mapping that maps between UUIDs and the names chosen by the user and viceversa. * Internally, in rules, folders, group, etc. which refer to named entities, use only the UUIDs, *never* user chosen names. * When presenting the internal structures to the user for reading or modifying, map the UUIDs to the names and viceversa. A rename then becomes a simple matter of updating the mapping between the name and the UUID and does not require the complex operations you describe. Just to make it clear, this is not a new invention but it is a simple application of well-known db engineering best practices. Regards
