Hi List & Devs, I heavily rely for my setup on host and service groups. They come handy for all kind of goals, mainly - to create reports - to issue mass commands - to create visual overviews Having the ability to make groups a member of groups is already pretty nice from an organisation perspective. But I very often find myself in the situation where I need to create many group combinations. A small example: A group windows_hosts and linux_hosts A group production and test A group datacenter_us and datacenter_eu In order to create views and availability reports such as: "production windows hosts from the eu datacenter" I need to create a groups like datacenter_us_production_linux datacenter_eu_production_linux datacenter_eu_test_linux datacenter_us_test_linux ...... And make the hosts member of these, .... This is still feasible for this amount of groups, but as you know, this grows rather fast and becomes extremely cumbersome. It would be nice to have the ability to add a host or service to multiple groups, like now and to have the ability to select hosts or services with AND OR NOT parameters. Show all hosts which are member of datacenter_us AND production AND linux_hosts We're going to patch all windows test servers in eu datacenter this weekend. Apply scheduled downtime on all hosts & services member of datacenter_eu AND test AND windows_hosts OR what would be completely awesome to have something like this (simplified example) define servicegroup{ servicegroup_name linux_us_production servicegroup_members_occur linux_hosts AND production AND datacenter_us } <div> <pre> What are your thoughts on this? -- Jelle Smet http://www.smetj.net</pre> </div>
