[checkmk-commits] Check_MK Git: check_mk: Normaly it is not allowed to have different hosts with equal name in Check_MK.

Module: check_mk Branch: master Commit: 25acf6382d0ce04a695ba2990db9e866612ae74c URL: http://git.mathias-kettner.de/git/?p=check_mk.git;a=commit;h=25acf6382d0ce0… Author: Lars Michelsen &lt;lm(a)mathias-kettner.de&gt; Date: Fri May 22 12:56:53 2015 +0200 Normaly it is not allowed to have different hosts with equal name in Check_MK. But it is possible to configure this, e.g. by creating hosts with an equal name on different sites (we do not recommend to do this). This change tries to fix handling of this situation in the GUIs views, where a user clicks on a host/service which is present on multiple sites but the user intends to get the host/service from a specific view. In the past this situation was not handled clearly which lead to a view showing data of the two equal named hosts where the user expected only data of one.
