JSON Key/Field Extraction

[jamesmcgee]

I have a json formatted output, which according to jsonlint.com is valid JSON.... but, am having problems extracting out the data into relevant "fields", for indexing...

}

For each key in the data list, I'd like to parse it out into an indexable/reportable field... and, if I was really lucky, the extraction routine would use the name field from each key..

"key": "DP3",
"value": "0",
"unit": "W",
"name": "DC Power PV3"

Am reasonably comfortable with field extractions usually, and have searched various existing posts, but I don't seem to have come across a solution for this specific scenario.

Any/all help really appreciated.

Thanks

I should have included, that Splunk does seem to recognise there are values in they "keys", but doesn't extract them as individual fields... 

So, I guess what I am looking for here, is for Splunk to pull out the dataList{}.name, and the corresponding dataList{}.value as a field/key-pair.

Thanks
