I have one log file where the Msg part contains many things like transaction id, error code, marchend name, etc
But these things are based on a group separator and field separator, so if i want any value like transaction id
, I need to count which GS (group separator) or inside GS which FS (field separator) this value is present.
I pasted here a small part of my log file. If you open it in notepad++ you are able to see FS and GS, but via splunk or normal notepad, you are not able to see this FS GS.
my log file is:

So i want to know how i can read values base on GS or FS position in splunk.
You could use the FIELD_DELIMITER
option in your props.conf
to seperate fields by FS (file sepeator). I would recommend to edit the props.conf directly in np++ to make sure the right char is in place.
http://docs.splunk.com/Documentation/Splunk/6.2.2/Admin/Propsconf
Other then that: use regex knowing that \x1D
matches GS and \x1C
matches FS:
... | rex field=_raw "(?:[^\x1d]*\x1d){6}(?:[^\x1c]*\x1c){10}(?<myfield>[^\x1c\x1d]*)"
This would evalute on the field _raw and within there go after the 6th occurance of GS and within there after the 10th occurance of FS and take everything until the next GS/FS into the field myfield. This of course presupposes that the values are ALWAYS on the same "position".

For FIELD_DELIMITER i already taken is tab because if you see in header(ProgID ThreadID InternalSeq PortalSeq LogTime Msg)
every field is separated by tab but in Msg field is also separate in may part by GS of FS .so field inside msg i want to take base on GS and FS
i use this rex field=_raw "(?:[^\x1d]*\x1d){6}(?:[^\x1c]*\x1c){10}(?[^\x1c\x1d]*)"
but i got error:
Error in 'rex' command: Encountered the following error while compiling the regex '(?:[^\x1d]*\x1d){1}(?:[^\x1c]*\x1c){2}(?[^\x1c\x1d]*)': Regex: unrecognized character after (? or (?-
I had to edit my post above (angle brackets).
Add an EXTRACT field extraction stanza to props.conf:
http://docs.splunk.com/Documentation/Splunk/6.2.2/Knowledge/Createandmaintainsearch-timefieldextract...
This would result in something like this:
[sourcetypeStanza]
...
EXTRACT-myfield = (?:[^\x1d]*\x1d){6}(?:[^\x1c]*\x1c){10}([^\x1c\x1d]*) in Msg
i use this line in props.conf but myfield not coming in field
[field serp]
FIELD_DELIMITER = tab
INDEXED_EXTRACTIONS = csv
KV_MODE = none
NO_BINARY_CHECK = false
SHOULD_LINEMERGE = false
category = Structured
description = Comma-separated value format. Set header and other settings in "Delimited Settings"
disabled = false
pulldown_type = true
EXTRACT-myfield = (?:[^\x1d]*\x1d){1}(?:[^\x1c]*\x1c){2}([^\x1c\x1d]*) in Msg
When i use this search with EXTRACT-myfield = (?:[^x1d]x1d){1}(?:[^x1c]x1c){2}([^x1cx1d])
in Msg in props.conf. After that I ran this search:
index=myrr | rex field=_raw "(?:[^x1d]x1d){6}(?:[^x1c]x1c){10}(?[^x1cx1d])"
Then i got my field thank you
