Json Event Breaking Issues

[NickLaurent]

Hi Folks,

Splunk Ent V6.5.2

I have a curly one here. I have a Json file ( sample below).
When the file is ingested events don't always get separated. The props is on a HF.

Thanks in advance.

I have the following props.conf.

[ ss_api2 ]
CHARSET=UTF-8
NO_BINARY_CHECK=true
SHOULD_LINEMERGE=false
TIME_PREFIX=timestamp
TRUNCATE = 500000
category=custom
description=Slipstream Prod/Beta api.
disabled=false
pulldown_type=true

Json sample:

{ "details": "{ \"exception\": \"Autofac.Core.Registration.ComponentNotRegisteredException: The requested service 'DigitalPlatform (DeploymentDashboard.Services.Configurations.IConfigurationsService)' has not been registered.

You probably need to define a LINE_BREAKER in your props. With linemerge set to false, the default line breaker is crlf, which won't work for your events.

For example, if the the details tag is the beginning of the new event, it might look something like below. The first capture group is what splunk will split the events on, the second group is just a lookahead to ensure it is just before the details tag.

Also, if you're going to include the time prefix, might as well include it exactly as it is and the format if it's consistent...

[ss_api2]
SHOULD_LINEMERGE=false
LINE_BREAKER=([\r\n\s]*)(?=\{\s*"details":)
TIME_FORMAT=%Y-%m-%d %H:%M:%S.%4n
TIME_PREFIX="timestamp":\s*"
MAX_TIMESTAMP_LOOKAHEAD=25
