Probably a bug in the migration script. Though we’ve seen many users trying to configure Icinga 2 the old-fashioned way like Nagios did, and therefore missing all the advantages Icinga 2 is able to provide. I would not recommend to go the route of such a migration script. Instead, do an inventory of your existing configuration items and look for 1) existing CheckCommand definitions provided by the ITL 2) write a proper CheckCommand if it does not exist (use command arguments, make it generic with optional arguments, but skip those crappy ARG1 to ARG999 non-telling arguments) 3) think about common patterns for your hosts adding for example custom attributes 4) apply services based on these patterns 5) add hosts to host groups based on these patterns 6) reconsider how notifications worked the old way - multiple contacts for hosts/services - and re-create notification apply rules for hosts/services in Icinga 2, adding your user/user_groups to it More hints on the documentation itself, be it the migration related one, or monitoring basics. Sooner or later I’ll remove the migration script from git. Even if it did cost multiple nights and weekends to code it, the outcome isn’t satisfying compared to what we are able to accomplish using the Icinga 2 dsl.
