Not really. You can still achieve the exact same functionality with custom variables. What Michael has done is to make one such custom variable "official", which breaks the ABI. He still has to use special plugins to check both ip4 and ip6 addresses at the same time, which is why I think it's quite stupid. > In fact, not being able to handle the "more-than-one-IP-per-host" in a > non-complex way is one of the greatest beefs I have with Nagios (see > web server, or a host which serves multiple services on different IP > addresses). > You can, but with custom variables. How many "official" addresses should Nagios support? 3? 5? Soon we'll run into someone who wants more than that, and then we're left with breaking the ABI again. And again. And again. Breaking the ABI causes major headaches for module developers and users. Custom variables don't break the ABI and causes minor headaches for people with complex environments, who hopefully get paid quite a lot to handle such complexities in an elegant way. Nagios makes that possible, while making the normal case (ip4 *or* ip6) possible. I'm sorry, but I'm not overly moved by your plea. -- Andreas Ericsson andreas.erics...@op5.se OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 Considering the successes of the wars on alcohol, poverty, drugs and terror, I think we should give some serious thought to declaring war on peace. ------------------------------------------------------------------------------ EditLive Enterprise is the world's most technically advanced content authoring tool.
