Hi

I have logstash config that send logs to Splunk HEC.

these data contain field that call "time".

Now question is: Is it possible to consider "time" as "_time" on logstash config?

 

FYI: i want to consider this time as _time not the time that splunk receive it

 

Any idea?

Thanks

As you send it via HEC you must told to splunk which field you want to use as _time otherwise it's used it's own heuristic to try to guess the correct time.

Here is described how this is happening https://docs.splunk.com/Documentation/Splunk/latest/Data/HowSplunkextractstimestamps

As splunk can guess timestamp is it possible to send data from logstash in somehow that splunk consider e.g field that in json format called “time” consider as _time?

without change splunk settings?
