Hi in my events I am getting time which is extracted correctly by Splunk for _time timestamp and for date extraction I want to use source field which is in format like-
From above source field I want to extract last 6 digit before .txt to create date like for this example it will be
What will be best way to do that..
Is it using datetime.xml? and how I can achieve it since for year only two digits are mentioned.
Which version are you running ?
If Splunk 7.2+, have a look here :
This is a pretty easy way to get time extracted at index time.
Thanks For your suggestion @DavidHourani ..Yes I am using Splunk 7.2+
But I thought that it will impact performance so I am trying to avoid it (Ingest Eval).
Yeah true, there would be an impact... In that case have you tried simply setting
TIME_FORMAT in your
This will first apply to the events and then fallback to the filename if it's not found in the event, so it should grab your time from there.
Currently I am trying with changing datetime.xml and if that fails then I will try TIME_FORMAT as well. So is there any performance impact if I use separate datetime.xml for app?
Yeap you can also do it with
datetime.xml it's just as good as
TIME_FORMAT, I thought you were looking for an easy solution that's why I didn't mention
datetime.xml, if you have that working stick to it ^^
HI @DavidHourani ,
I want one day before of extracted date as _time How I can achieve this?
like from source I have extracted as 10 June then I want _time as 09 June..
You can do this at search time with something like this :
...| eval _time=_time-86400
Or save that as a calculated field to have it permanently applied at search time.
Best would be to go back to
IngestEval it's the only way to apply an eval at index time..
Or if you can manipulate your filenames, then fix it to day -1 🙂
My current problem:-
my event looks like-
31,04:56:47:928, abc:0xabc, 49.716720, -59.271553,197
where 31 is day of month
and source field looks like -
So by which way I can get _time as 31 May 2019?
and for same source some events looks like
30,04:56:47:928, abc:0xabc, 49.716720, -59.271553,197
For which I want _time as 30 May 2019
ouch, so same source, different ways to extract time, is that what you mean ? coz for both events you posted it seems you can get everything from the event itself, except the month, right ?
refer here for the exact eval to be used :
