Having issues with props.conf file: avoid line breaking after newline and carriage return

Hi Splunkers,

I'm on an addon creation task, Glassfish in particular and, like other times I faced tese kind or request, I'm configuring the props.conf file.

In this configuration I'm facing the following issue: I know that events starts with two kind of character sequences:

  1. [#|
  2. Date in format month (3 letters) and day, so for example Jun 07

So, in BREAK_ONLY_BEFORE, i putted the following regex: 

 

 

 [\[\#\|] | [\w{3}\s\d{2}]

 

 

 and it works fine.

A problem rise in the second case: when this events are present, they have a structure with many carriage return. Here a log sample:

 

 

Jun 07, 2022 8:29:52 PM <some_path_here>info
INFO: JVM invocation command line:
-XX:+UnlockDiagnosticVMOptions
-XX:MaxPermSize=<size>
-XX:PermSize=<size>
-XX:NewRatio=<size>
-Xms<size>
-Xmx4096m
<other lines that starts always with - symbol>

 

 

 In such case, the default event line breaking split every info in this events in a different events. So, I set 

 

 

SHOULD_LINEMERGE=1

 

 

but I have still problems; even with this configuration, the events are not properly merged. What I got are 3 different events splitted in such a way::

 

 

Jun 07, 2022 8:29:52 PM <some_path_here>info

 

 

first part of info starting with - symbol, so:

 

 

INFO: JVM invocation command line:
-XX:+UnlockDiagnosticVMOptions
-XX:MaxPermSize=<size>
-XX:PermSize=<size>
-XX:NewRatio=<size>
-Xms<size>
-Xmx4096m

 

 

remaining part of info starting with - symbol, so:

 

 

-Djavax.net.<remaining path>
-Dcom.sun.enterprise.security.httpsOutboundKeyAlias=<value>
-DANTLR_USE_DIRECT_CLASS_LOADING=<value>

 

 

To fix this, I tried to use:

 

 

MUST_NOT_BREAK_AFTER=[\r\n]+

 

 

but it does not work. The event is still divided in the above 3 different parts.

How can I fix it?

Hi

you could try this:

[<ST here>]
SHOULD_LINEMERGE=false
LINE_BREAKER=([\n\r]+)(\[#\||\w+ \d\d, \d\d\d\d)
NO_BINARY_CHECK=true
TIME_FORMAT=%b %d, %Y %I:%M:%S %p
TIME_PREFIX=^
MAX_TIMESTAMP_LOOKAHEAD=32
