timestamp extra

crazyeva — Mon, 28 Sep 2020 14:15:07 GMT

I put some oracle-exported data into splunk, with props.conf:

NO_BINARY_CHECK = true
CHARSET = GB2312
SHOULD_LINEMERGE = false
TIME_PREFIX = (?(?:\d{2}(?:\/\d{2}){2}\s\d{2}(?::\d{2}){2})|(?:\d{4}(?:-\d{2}){2}\s\d{2}(?::\d{2}){2}))(?=(?:^[^^]*){27}$)

same result,easy to read: TIMEPREFIX = (?[^\^]*)(?=(?:\^[^\^]*){27}$)

Most timestamps are extracted correctly, but two of them are unexpected:

event 1, 7/15/12 9:35:17.000 PM should be "05/03/12 15:56:32" and event 2, 7/15/12 9:27:02.000 PM should be "04/11/12 19:15:18" stong characters in raw

crazyeva,

That first TIME_PREFIX makes my head hurt. Let's go with something closer to your second example.

I would do something along these lines:

TIME_PREFIX = ([\r\n]+)(?([^^]+^){14})

Sorry to reply so late.
The number of "^" is not sure from line starts, so i tried to find timestamp from their tails.
By the way, I am confused that TIME_PREFIX attempts to match what is before timestamp or just to match timestamp?

TIME_PREFIX is used to tell Splunk what comes before the timestamp.

Also, in that TIME_PREFIX that I provided, the regex in the first set of parenthesis will match any number of returns or newlines.
