Checkmk Werk 15483: Fix missing metric history values on edit

ID: 15483 Title: Fix missing metric history values on edit Component: Multisite Level: 1 Class: Bug fix Version: 2.3.0b1 The metric history is or can be used in different places, e.g. the gauge dashlet or in columns of views. If you have used e.g. a column with "Service: Metric History" in a view and edited the view again, the default value was always shown. Note: The settings were stored correctly, this was just a display bug.
