Answer 1

jq solution:

jq 'group_by(.organizationId) 
    | map(reduce .[] as $o ({"Down_Count" : 0};
              if $o["status"] == "DOWN" then .Down_Count += 1 else . end
              | . + { ($o["server"]) : $o["status"],
                          "organizationId" : $o["organizationId"] }
          ))' input.json

The output:

[
  {
    "Down_Count": 2,
    "server1": "UP",
    "organizationId": "org1",
    "server2": "DOWN",
    "server3": "DOWN"
  },
  {
    "Down_Count": 0,
    "server1": "UP",
    "organizationId": "org2",
    "server2": "UP"
  }
]
