I am currently running 3.2.3. I have quite a few machines running nagios and all but one are running happily with very similar configs (hosts/services differ from machine to machine, but all other files are identical). I get a config check error on one that is very strange. #### Snipit of hostgroup config file that doesn't work (identical on all machines) define hostgroup { hostgroup_name Consumer Electronics alias Consumer Electronics } #### running nagios -v ../nagios.cfg get this (please note, the corrupt characters change every time I run the verify process) .... lines ommited .... Checked 15 hosts. Checking host groups... Error: Host 'ир' specified in host group 'Consumer Electronics' is not defined anywhere! Checked 11 host groups. .... lines ommited .... Total Errors: 1 #### changing the "C" in consumer electronics to a "c" fixes it (or, from a cursory check, any letters except "A", "B", or "C") - see modified snipit define hostgroup { hostgroup_name consumer Electronics alias Consumer Electronics } ##### config check runs perfectly!!! Note: It so happens that this hostgroup is not even in use on this particular machine. I just have a standard hostgroup config file that gets distributed to all machines. I think this is a bug, but I cannot find any information that shows one already logged, and I don't really know how to confirm exactly what is causing the verify process to believe there is a host with the garbage characters. Any suggestions would be great!
