Description
This unit is a Source unit type.
The Devo Last Event Date unit finds the date of the latest event in a specified Devo table and appends it to the input event in the field set in the properties.
Once an event enters through the in port, the query specified in the properties is issued.
Events are output through the data port with the date of the last record in the table is added to the event in the field indicated in configuration.
If an error occurs, the events are enriched with standard error fields and set to the error output port.

Example
In this example, we want to send an event every ten seconds to the Devo Last Event Date to show how the time of this last event is inserted into a specified data table in Devo.
To do it, we will add a Scheduler unit that will send events to the table every ten seconds.
Then, we will define the destination table using the Devo Last Event Date unit as siem.logrust.web.activity.
Link the out port of the Scheduler unit to the in port of the Devo Last Event Date unit.
