Splunk Search

How do I extract data from this aide output



I had originally handles this with HUGE pile if SED commands and loops in a BASH script. But I am thinking there has to be a "Splunk" way of extracting these field.

 Inode    : 203813077                        , 203813089
 ACL      : old = A:
                  😧 <NONE>
            new = A:
                  😧 <NONE>

The area the challenges me the most is the multiple "changed" in a single log file. And of course the detail area. Any recommendations? Starting points.

There  is an option in aide to get the logs in syslog format (in a single line). Please add the below lines in aide.conf. 

syslog_format = true



In man pages about aide.conf

Valid values are yes,true,no and false. This option enables new syslog format which is suitable for logging. Every change is logged as one simple
line. This option changes verbose level to 0 and prints everything that was changed. It is suggested to use this option with "report_url=syslog:...".
Default value is "false/no". Maximum size of message is 1KB which is limitation of syslog call. If message is greater than limit, message will be
truncated. Option summarize_changes has no impact for this format.

Output always starts with:
"AIDE found differences between database and filesystem!!"
And it is followed by summary:
And finally there are logs about changes:
dir=/usr/sbin;Mtime_old=0000-00-00 00:00:00;Mtime_new=0000-00-00 00:00:00;...

Do you have any control over the output of this script? Is this something custom you are running?

It depends on what you need to do with the information in the log. What do you need out of it and how are you planning to use it?


Good point, I was trying to do everything. I went in and shrunk down my needs. SEDCMD's all the junk that I don't want. Thanks for the wake up there.
