ID: 11032 Title: Fixed consideration of local 'old style' perfometer customizations Component: Multisite Level: 1 Class: Bug fix Version: 1.7.0i1 If a perfometer definition like: <b>perfometers["check_mk-mem.linux"] = my_perfometer</b> is set in '~/local/share/check_mk/web/plugins/perfometer" and the key is already present within the builtin perfometers, the local definition had no effect.
