How to print nested JSON array data in a tabular format? - json

Question

I want to read the status of clusters and servers inside it.
Below is the sample json file

}
}]
So in each cluster we have two servers and this json continues to have around 15 clusters.
I want to filter out the status of each cluster and server in below format
name cluster/server status
gw-ext-1 CLUSTER RUNNING
gw-jpg208765-1 SERVER RUNNING
gw-jpg208765-2 SERVER DISCONNECTED
similarly for other clusters also.
I tried few things but its not giving me the servers .. it gives only cluster's details
target_id=echo \$targetIdResponse | ${env.WORKSPACE}/jq -r '.data[] | [.name, .type, .status]'
OR
target_id=echo \$targetIdResponse | ${env.WORKSPACE}/jq -r '.data[] | [.name, .type, .status, .servers.name, .servers.type, .servers.status]'
where $targetIdResponse contains my json data
I want to know how i can filter the above json to get the required data.

You need to have the header array the required fields in a separate array and put them together in a tabular format using #tsv
jq -r '[ "name", "cluster/server", "status" ],
( .data[] | [.name, .type, .status] ),
( .data[].servers[] | [ .name, .type, .status ] ) | #tsv'
The requirement was modified since originally posted to have the server information exactly below the cluster information
jq -r '[ "name", "cluster/server", "status" ],
( .data[] | [.name, .type, .status], ( .servers[] | [.name, .type, .status] ) ) | #tsv'
