Getting Data In

Log4g (via Syslog) not working for multiline indexing?

I'm working on trying to get our application server's log4j working so that events will show up in searches for multiline events as a single event. There is also a problem where there are "..." breaks where the multiple lines should just continue on.

Here is an example output:

2013-07-25 14:31:49,813 [pool-4-thread-1] INFO  net.app.security.Filter (269) - Exiting ClusteredLogoutFilter#sessionCreated - Timestamp : 1374777109813

--------------------------------------

I assume that this is a problem within my log4j/syslog configuration on the sending server that is causing this?

The other thing, which I'm not sure that it's an issue is, say I search on "1.1.1.1" , only the line that has this will show up in the search, not the full set of lines that I'm expecting. I would have click on this entry and then do a "Show Source" to see the full lines.

Any ideas would be great. I have this in my config:

props.conf


[log4j]
TRANSFORMS--strip-syslog = syslog-header-stripper-ts-host

[log4j]
BREAK_ONLY_BEFORE =
BREAK_ONLY_BEFORE_DATE = true
SHOULD_LINEMERGE = true
TIME_FORMAT = %Y-%m-%d %H:%M:%S,%3N
TIME_PREFIX = ^
MAX_TIMESTAMP_LOOKAHEAD = 25

Thanks!
Jeff

It looks like the syslog timestamp/hostname was not being stripped out in some cases.
