Field value watcher

The Field Value Watcher will look at data changes over time to detect when a KPI goes out of a normal state.

Field value watchers have three tabs to configure :

Data selection

This is where you define which Widget will be used to get the data : the Source Widget.
The list contains all Widgets of the selected Dashboard.

*The Field Value Watcher requires a Date field, so you must have at least one in your widget.

Condition details

This is where you configure the condition itself.

Select field to watch

Select which measure field from the data of the Widget you need to watch.

Value does not change / Value changes

Select if you want to be alerted when the value stays the same, or when the value changes.

Duration deadband

Allows to define a deadband to ignore changes that happen too fast.
This requires a date field from the Widget.

If the duration between two consecutive constant values is always smaller than the Deadband, then the abnormal values are ignored.

Consider value changed when outside of following bound

This allows to define a value interval to consider that the value really changed.
This can be expressed in absolute value, or As percent of the target value.

Filter

You can also filter the result to only accept some data :

You can create a filter on a string field for example.
