SYMPTOM:
A threshold may be created for a metric and while it seems like the metric values should match the threshold definition, the threshold is still not applied. For instance, a threshold might be defined for 'New Metric' values greater than or equal to 0.2:
Yet the threshold is not applied to 'New Metric' values that display as 0.2:
CAUSE:
One possible cause is that the metric values are being rounded. The threshold application is not based on how the metric value is displayed, but on the full metric value. Using the example above, if the formatting for the metric values are edited to show a greater number of decimal places, the values are all shown to have been rounded up to 0.2.
ACTION:
In order to set a threshold for all metric values that will display as 0.2 or higher, the threshold should be set to include all values 0.15 or higher. Note that in this case, several values are being rounded up to 0.15, so the threshold is not applied. However, if the number of metric value decimal places displayed is switched back to 1, the threshold display will not be confusing.
