Getting Data In

Json without duplicates

Good afternoon guys,

We need help.

We have a JSON file in which duplicate events are written.

We want to know how to have a primary key so that it does not index those duplicates and is not in the Splunk index.

{
"security": {
"notices": [
{
"rss_published": "2019-02-12T13:33:31.000Z",
"rss_message": "Email provider VFEmail has suffered what the company is calling \"catastrophic destruction\" at the hands of an as-yet unknown intruder who trashed all of the company's primary and backup data in the United States. The firm's founder says he ....",
"rss_fuente": "rss_krebsonsecurity",
"rss_title": "Email Provider VFEmail Suffers \u2018Catastrophic\u2019 Hack",
"rss_link": "https://krebsonsecurity.com/2019/02/email-provider-vfemail-suffers-catastrophic-hack/"
}
]
}
}

But there is no method that at the time of indexing look at two fields of the json and make a hash or something so that these duplicates do not exist

There may be something possible using the DSP beta, but at this point in time, it would be much less efficient to do it inside of Splunk - you would potentially cause some amount of ingestion latency.

You can use Cribl to preprocess this... @clintsharp @dritan

I think you'd be better off doing this at the source rather than in Splunk. Is it possible to write a script to cleanse the data before it's written to a file that Splunk monitors?
