Getting Data In

timeparsing issue for sourcetype

Explorer

I have data like below:-

Log file created at: 2019/03/24 17:56:14
Running on machine: F8976GMac
Log line format: [IWEF]mmdd hh:mm:ss.uuuuuu threadid file:line] msg
I0324 17:56:14.700251 16884 server.cpp:116] - 144.77.88.67
I0324 17:56:14.747052 16884 server.cpp:118] - Listening at : 28888, 28889, 28890

and i am getting following Warnings in _internal logs:-

WARN DateParserVerbose - Accepted time (Wed Jul 6 07:27:19 2016) is suspiciously far away from the previous event's time (Fri Apr 5 07:27:19 2019), but still accepted because it was extracted by the same pattern.

Please let know what timeparsing config fix can be made here since i see the same log file prints the complete timestamp at the start only and then only time is getting printed.

Try this in props.conf on the first full instance of Splunk that handles the events (usually Heavy Forwarder or Indexer tier):

[YourSourcetypeHere]
TIME_PREFIX = "Log file created at:\s*"
TIME_FORMAT = %Y%m/%d %H:%M:%S
MAX_TIMESTAMP_LOOKAHEAD = 19
LINE_BREAKER = (?!)
SHOULD_LINEMERGE = false
TRUNCATE = 99999

This makes every line in the file a single event.

Hi,

Please try below config on Indexer/Heavy Forwarder(whichever comes first from UF).

props.conf

[yoursourcetype]
TIME_FORMAT=%Y/%m/%d %H:%M:%S
TIME_PREFIX=created\sat\:\s
MAX_TIMESTAMP_LOOKAHEAD=19

This is further breaking events since 256 char limits have exceeded.

The other events are giving warnings as they failed to parse timestamp.

In this case you can add below settings in above props.conf or you can adjust below settings based your actual event size and length.

MAX_EVENTS = 1000
TRUNCATE = 50000

Applying these settings is breaking the events because limit of 256 characters has breached. Thus the other events produced are also giving the warning of failure in parsing timestamp in MAXTIMESTAMPLOOKAHEAD. The two sample events created are following:-
