DCS does not push data. You pull the data directly from the database using the built-in read-only scsp_plugin SQL account.
Most 3rd party tools like SSIM, Splunk and ArcSight have a database connector.
Use this query for starts:
select * from CSPEVENT_VW where EVENT_ID > [the last event ID you pulled at the last poll]
Note that SCSPDB is the default name of the DCS database, you may have changed that.
