Hi everyone,
I have several oracle audit logs received via syslog-ng + splunk file inputs:
Jul 8 14:44:04 192.168.160.20 Audit[11206800]: LENGTH: "323" SESSIONID:[9] "359691618" ENTRYID:[1] "1" STATEMENT:[1] "1" USERID:[7] "SYSTEMA" USERHOST:[22] "host.domain.xy" ACTION:[3] "208" RETURNCODE:[1] "0" COMMENT$TEXT:[98] "Authenticated by: DATABASE; Client address: (ADDRESS=(PROTOCOL=tcp)(HOST=192.168.160.21)(PORT=14039))" OS$USERID:[6] "apache" DBID:[10] "3473254904"
Jul 8 14:47:57 192.168.160.21 Audit[27328736]: LENGTH: "156" SESSIONID: "270416291" ENTRYID: "1" ACTION: "101" RETURNCODE: "0" LOGOFF$PREAD: "0" LOGOFF$LREAD: "21" LOGOFF$LWRITE: "0" LOGOFF$DEAD: "0" SESSIONCPU: "0"
My regex
(?i)(?<_KEY_1>\S+):(\s|\[\d+\])+"(?<_VAL_1>[^"]+)"
My props.conf
[oracle_aud]
SHOULD_LINEMERGE = true
BREAK_ONLY_BEFORE_DATE = false
BREAK_ONLY_BEFORE = \d\d\d\s\d\d\s\d\d:\d\d
TIME_PREFIX = ^
TIME_FORMAT = %b %d %H:%M:%S
EXTRACT-oracle_action_returncode = (?i)(?<_KEY_1>\S+):(\s|\[\d+\])+"(?<_VAL_1>[^"]+)"
LOOKUP-oracle_action = oracle_action_csv ACTION AS ACTION OUTPUTNEW ACTION_DESCRIPTION AS ACTION_DESCRIPTION
LOOKUP-oracle_returncode = oracle_returncode_csv RETURNCODE AS RETURNCODE OUTPUTNEW RETURNCODE_DESCRIPTION AS RETURNCODE_DESCRIPTION
I cant solve 2 problem.
1. Several events displayed in one line.
2. It is possible to extract source ip (192.168.160.20) and Audit fields value (11206800|27328736) with one regex expression?
I have tried this one too, but not really worked:
BREAK_ONLY_BEFORE = ^(Jan|Feb|Mar|Apr|May|Jun|Jul|Aug|Sep|Okt|Nov|Dec)\s

#1: Change to this instead:
BREAK_ONLY_BEFORE = \w{3}\s+\d+\s+\d+:\d+
#2:
EXTRACT-srcip_and_autid = (?<srcip>\d+\.\d+\.\d+\.\d+).*?Audit\[(?<Audit>\d+)
This regex string will extract the source IP and Audit fields
(?P<source_ip>\d+\.\d+\.\d+\.\d+) Audit\[(?P<audit>[^\]]+)]

BREAK_ONLY_BEFORE = \w{3}\s+\d+\s+\d+:\d+

EXTRACT-srcip_and_autid = (?<srcip>\d+\.\d+\.\d+\.\d+).*?Audit\[(?<Audit>\d+)
Extracting other fields works well, Thank you all.
i think timestamps were extracted well. I can see _time field and other time/date fields:
date_hour,date_mday,date_minute,date_month,date_second,date_wday,date_year,date_zone=local
No idea why does not work...
(Replacing sourcetype to syslog in inputs.conf line merge works well.)
Do you really need to linemerge? If you don't, then changing to this should prevent mis-merged lines:
SHOULD_LINEMERGE = false
Option "SHOULD_LINEMERGE = false" solved it.
