Splunk Search

How do I auto extract fields from JSON event?

Hi there after much searching and testing i feel i'm stuck. Or even unsure what i want is possible. 

What i want

I have _json data indexed. Each event is a long array. I want Splunk to automatically make key:value pairs per value. Until now, Splunk gives me all the values instead of 1 single value. Also it seems Splunk can't make correlations between fields. 

I want to use fields so i can do simple searches, like making a table for "internal" "website_url"s and their  status ("up" or "down"). 

 

Example event

{"data":[{"id":"1234567","paused":false,"name":"https:\/\/some.random.url\/with\/random\/string","website_url":"https:\/\/some.random.url\/with\/random\/string","test_type":"HTTP","check_rate":60,"contact_groups":["123456"],"status":"up","tags":["internal"],"uptime":100},{"id":"1234567","paused":false,"name":"https:\/\/some.random.url\/with\/random\/string","website_url":"https:\/\/some.random.url\/with\/random\/string","test_type":"HTTP","check_rate":60,"contact_groups":["123456"],"status":"up","tags":["internal"],"uptime":100},{"id":"1234562","paused":false,"name":"https:\/\/some.random.url\/with\/random\/string","website_url":"https:\/\/some.random.url\/with\/random\/string","test_type":"HTTP","check_rate":60,"contact_groups":["123456","123456"],"status":"up","tags":["internal"],"uptime":100},{"id":"1234563","paused":false,"name":"https:\/\/some.random.url\/with\/random\/string","website_url":"https:\/\/some.random.url\/with\/random\/string","test_type":"HTTP","check_rate":60,"contact_groups":["123456"],"status":"up","tags":["internal"],"uptime":100},{"id":"1234564","paused":false,"name":"https:\/\/some.random.url\/with\/random\/string","website_url":"https:\/\/some.random.url\/with\/random\/string","test_type":"HTTP","check_rate":60,"contact_groups":[],"status":"up","tags":["internal"],"uptime":100},{"id":"1234567","paused":false,"name":"https:\/\/some.random.url\/with\/random\/string","website_url":"https:\/\/some.random.url\/with\/random\/string","test_type":"HTTP","check_rate":60,"contact_groups":["123456"],"status":"up","tags":["internal"],"uptime":100},{"id":"1234562","paused":false,"name":"https:\/\/some.random.url\/with\/random\/string","website_url":"https:\/\/some.random.url\/with\/random\/string","test_type":"HTTP","check_rate":60,"contact_groups":["123456"],"status":"up","tags":["internal"],"uptime":100},{"id":"1234560","paused":false,"name":"https:\/\/some.random.url\/with\/random\/string","website_url":"https:\/\/some.random.url\/with\/random\/string","test_type":"HTTP","check_rate":60,"contact_groups":["123456"],"status":"up","tags":["internal"],"uptime":100},{"id":"1234562","paused":false,"name":"https:\/\/some.random.url\/with\/random\/string","website_url":"https:\/\/some.random.url\/with\/random\/string","test_type":"HTTP","check_rate":60,"contact_groups":["123456"],"status":"up","tags":["internal"],"uptime":100},{"id":"1234568","paused":false,"name":"adyen","website_url":"https:\/\/some.random.url\/with\/random\/string","test_type":"HTTP","check_rate":300,"contact_groups":["123456"],"status":"up","tags":["external"],"uptime":100},{"id":"1234567","paused":false,"name":"paynl","website_url":"https:\/\/some.random.url\/with\/random\/string","test_type":"HTTP","check_rate":300,"contact_groups":["123456"],"status":"up","tags":["external"],"uptime":100},{"id":"1234562","paused":false,"name":"trustpay","website_url":"https:\/\/some.random.url\/with\/random\/string","test_type":"HTTP","check_rate":300,"contact_groups":["123456"],"status":"up","tags":["external"],"uptime":100},{"id":"1234563","paused":false,"name":"https:\/\/some.random.url\/with\/random\/string","website_url":"https:\/\/some.random.url\/with\/random\/string","test_type":"HTTP","check_rate":300,"contact_groups":["123456"],"status":"up","tags":["external"],"uptime":100},{"id":"1234566","paused":false,"name":"spryng","website_url":"https:\/\/some.random.url\/with\/random\/string","test_type":"HTTP","check_rate":300,"contact_groups":["123456"],"status":"up","tags":["external","sms

How far i got

 

source="/opt/splunk/etc/apps/randomname/bin/statuscake_api.sh" | spath output=id path=data{}.id | spath output=url path=data{}.website_url | spath output=status path=data{}.status | search id=8179640 | table id, url, status

 However, it shows a table of all aray fields, not just one specific 'id' i specified in the search part | search id=<idnumber>

Guess i used the wrong commands. 

Solution:

 

 

earliest=-1min source="/opt/splunk/etc/apps/appname/bin/scriptname.sh" | stats values(data{}.status) as status, latest(data{}.uptime) as uptime by data{}.website_url

Okay, because editing is not working, here the screenshot it should've attached.

Here you can see Splunk returns 1 row with all id's instead of 1 row with 1 specific id.

 

The dirty way i would manage to get what i want is line breaking during index time. Where each ID would be a new event. And then do a transform and fieldextraction. But i feel like thats not the proper route as so many people use json input, i cannot imagine one should do this extensive setup for each json input.
