props.conf config for line breaking

Hi All,

I am having problems splitting lines of a log file.
the log entry is below;

[DEBUG 2019-09-26 09:15:57:765] Logger Proxy STARTED
[DEBUG 2019-09-26 09:15:57:765] Logger Servlet Called (13024624) times
[DEBUG 2019-09-26 09:15:57:765] Logger SetResponseDefaults
[FATAL 2019-09-26 09:15:57:765] Logger Proxy - Illegal or missing SubscriberId

below is my props.conf file entry

[jams_log]
SHOULD_LINEMERGE = true
BREAK_ONLY_BEFORE_DATE = false
BREAK_ONLY_BEFORE = ^[\D{5}\s\d{4}-\d{2}-\d{2}\s\d{2}:\d{2}:\d{2}.\d{3}]
MAX_TIMESTAMP_LOOKAHEAD = 31
TIME_PREFIX = ^

I thought it was because i did not have TIME_FORMAT, however this did not work either.

any help would be much appreciated.

Hi ssaenger,
at first I suggest to test your props.conf using the guided web interface.
Than, did you tried SHOULD_LINEMERGE=false?
Then I see that the TIME_PREFIX isn't correct, so try something like this:

[jams_log]
SHOULD_LINEMERGE = true
LINE_BREAKER = \[\w+\s+\d{4}-\d{2}-\d{2}\s+\d{2}:\d{2}:\d{2}.\d{3}\]
MAX_TIMESTAMP_LOOKAHEAD = 29
TIME_PREFIX = ^\[\w+\s+

Bye.
Giuseppe
