The following is an example SQL statement that demonstrates how data can be extracted from the QryLogEventHisV view to show Flex Throttle events.

sel entryts,
    substr(entrykind,1,10) "kind",
    substr(entryname,1,20) "name",
    cast (eventvalue as float format '999.9999')  "evt value",
    cast (lastvalue as float format '999.9999') "last value",
    spare2  "spare Int",
    substr(activity,1,10) "activity id",
    substr(activityname,1,20) "act name", seqno, flexthrottleid, flexthrottleseqno from dbc.tdwmeventhistory order by entryts, seqno;

The query returns the following result:

                   EntryTS  kind        name                  evt value  last value  spare Int activity id act name  SeqNo  FlexThrottleID  FlexThrottleSeqNo
