I believe I have discovered a bug (and hope this is the correct place to report it). In Configure --> Core Config Manager --> Monitoring --> Host Groups --> [select a group] --> Manage Hosts searching for a host simply does not work. You can enter text into the search at the top but it always returns 0 hosts. I found while playing with this if you enter a few letters into the search (i.e. "goo") then back space all three letters, then back space one more time all hosts disappear from the below lists. It seems that something in the coding for the search or the page is wrong.
Tested on version 5.6.13.
Please let me know if there is any more info you need here.
Bug: Host Groups Search Issue
Re: Bug: Host Groups Search Issue
Are you seeing this behavior in Chrome? The issue should be fixed in Nagios XI 5.6.14. I would recommend that you upgrade your XI instance to the latest to see if this is going to resolve your issue. You will have to clear your browser's cache too.
