Dashboards & Visualizations

Dashboarding from a JSON array.

Below is a sample event ingested over HEC and a query. What I am interested in is creating a dashboard from miner.gpus{}. I want to dashboard miner.gpus{}.eth, miner.gpus{}.temp, and miner.gpus{}.fan. The expected miner.gpus{} count is always 8.

Is there an easy way to create a gauge for every index in the array? Or do I have to manually call out the index using mvindex?

index="rigs" rig="$miner$"
| spath output=values miner.gpus{}.eth
| eval value=mvindex(values,0) 
| stats min(value) as minimum, max(value) as maximum, latest(value) as current 
| table current, minimum, maximum

[Updated] Since your miner.gpus{}.eth field always has 8 elements, I have created a loop of 8 using map command. (PS: map command will be expensive and depending on Splunk settings it might restrict number of times a subsearch may run (by default it is 10)

| makeresults
| eval counterIdx="0 1 2 3 4 5 6 7"
| makemv counterIdx
| mvexpand counterIdx
| table counterIdx
| map search="search source=\"splunk_answers_551950_json_data.json\" host=\"NiketNilay-PC\" sourcetype=\"_json\"
              | rename miner.gpus{}.eth as values
              | eval value=mvindex(values,$counterIdx$)
              | stats min(value) as minimum, max(value) as maximum, latest(value) as current 
              | table current, minimum, maximum"

Please see if this works, I have tested with the data you have provided. If the query is running too slow or not returning the desired result we might have to come up with different approach.

PS: Please take out/mask actual site/port name from jSON Data.


@cmisztur, if you need only the first value you can directly traverse to the same using 0 as index.

I need to traverse all indexes.
