ALL/ALERT tab

Figure 1. "All/Alert" tab

The ALL argument is used to read all archived data from the DB (using the Timerange argument on the Timerange tab you can specify the period for the query). If you do not specify a Timerange or ALL, the query returns current values from the DB.

Note: When using the option ALL, archive configs have to exist on each data point element that is defined in the query.

In connection with the SELECT statement, ALERT only queries alerts from the DB (see _alert_hdl).

Queries with ALL/ALERT, see chapter Queries.
