Check_MK Werk 1570: Fix notification of check_http active checks with Nagios core

ID: 1570 Title: Fix notification of check_http active checks with Nagios core Component: Notifications Level: 1 Class: Bug Fix Version: 1.2.5i7 When using Nagios as the core and a check command that contains single quotes then the notification would not work. This is because the variables are enclosed in single quotes in <tt>check_mk_templates.cfg</tt>. That file has been changed so that for the check command macros double quotes are being used. Check_MK itself does never use double quotes in its strings so this is less likely to cause problems. The Check_MK Micro Core does not have this problem. Everything works fine here.
