how to sum the machine OS in a JSON file

garumaru — Fri, 15 May 2020 13:12:51 GMT

Hi Guys,

I have a JSON file for OS type in some cluster like below:

{
"clusterA": ubuntu,
"clusterA": ubuntu,
"clusterA": rhel5,
"clusterA": sles11,
"clusterB": sles11,
"clusterB": sles11,
"clusterB": ubuntu,
"clusterC": centos,
"clusterC": ubuntu
...
}

I'd like sum the OS type for each cluster, like in above sample, 2 ubuntu in clusterA, 1 rhel5 in clusterA etc.
Would you please kindly help out?

Thank you!

 \"clusterC\": ubuntu}" 
| eval json=replace(json,"\"|{|\s|}","") 
| makemv delim="," json 
| mvexpand json 
| eval temp=split(json,":"),cluster=mvindex(temp,0),os=mvindex(temp,1) 
| stats count by cluster,os
