Checkmk Werk 15636: Predictive Levels: Show prediction if the value is 0

ID: 15636 Title: Predictive Levels: Show prediction if the value is 0 Component: Checks & agents Level: 2 Class: Bug fix Version: 2.3.0b1 Previously, the message C+: no reference for prediction yet C-: would be shown, if the prediction made by the CMC was <tt>0</tt>. With this Werk, the predicted value is now always shown. The prediction levels have been updated accordingly. LI: <tt>Absolute difference from prediction:</tt> 0 is treated like any other value. Some alarms, which used to be omitted, are now correctly reported. LI: <tt>In relation to standard deviation:</tt> 0 is treated like any other value. Some alarms, which used to be omitted, are now correctly reported. LI: <tt>Relative difference from prediction:</tt> Non-zero values are treated in a different manner. No dynamic levels are computed. This means the behaviour of this parameter has not changed with this Werk. Note, the configuration <tt>In relation to standard deviation</tt> can lead to false alarms, if the standard deviation is zero.
