Check_MK Werk 2060: check_mk perfometer metrics: fixed exception and two new functions

ID: 2060 Title: check_mk perfometer metrics: fixed exception and two new functions Component: Checks & Agents Level: 1 Class: Bug Fix Version: 1.2.7i1 Fixed an exception in dictionary perfometers when no labels were set. The "total" key in a dictionary perfometer can now be set to a fixed value. The new key "hide_label" in a dictionary perfometer hides any text. This might be useful in stacked/dual perfometers.
