Select tab

The SELECT statement specifies values to query from the DB. It must consist of at least "KF.DT.AT" (config_level.detail_level.attribute_level). Using the Configuration combo box you can select which datapoint attribute (for messages see _alert_hdl) of a datapoint/data point element to query.
