Custom multi-line parsing tip

I want to chop multiline events like below. I had splunk to automatically process the data, but it didn't quite work where the event started with "Begin_Event".
How can I define custom event separation rule so that the each evens starts after "Begin_Event" tag?

(Begin_Event)

environmentFailureEvent - EAS - KG-079, Cab 1, Pos 1, active ACG, EAS 0 - May 3, 2010 00:02:55. [247] Rectifier Module Fail - Clear
(EndEvent)

(BeginEvent)

processingFailureEvent - IHLR_ALARM_APP - KTIHLR1_B, IHLR_ALARM_APP 1 - May 3, 2010 00:02:49. [17260] Subscriber Not In iDEN HLR - Minor. RC:77 imsi=450079680700513

(EndEvent)

Just set:

SHOULD_LINEMERGE = false
BREAK_ONLY_BEFORE = ^\(Begin_Event\)

for your sourcetype or source in props.conf. Alternatively you could use:

SHOULD_LINEMERGE = false
LINE_BREAKER = ([\r\n]+)(?=\(Begin_Event\))

Variations of the above can remove the (Begin_Event) line as well.
