From eb2299a0897577048205e4d8a331168d82ce09d0 Mon Sep 17 00:00:00 2001
From: Noriko Hosoi <nhosoi@momo7.localdomain>
Date: Thu, 26 Jul 2018 17:18:38 -0700
Subject: [PATCH] Add a parameter skipempty to the json field type.
If skipempty is set as follows, empty json objects are dropped from
the parsed result.
%field_name:json:skipempty%
If any parameter other than "skipempty" is given ("bogus" in this
example), an error message "invalid flag for JSON parser: bogus"
is issued.

%description
Briefly described, liblognorm is a tool to normalize log data.
People who need to take a look at logs often have a common problem. Logs from
different machines (from different vendors) usually have different formats for
their logs. Even if it is the same type of log (e.g. from firewalls), the log
entries are so different, that it is pretty hard to read these. This is where
liblognorm comes into the game. With this tool you can normalize all your logs.
All you need is liblognorm and its dependencies and a sample database that fits
the logs you want to normalize.
