        }
      }
    ]
  }
}

To moze wrzuc jak ma wygladac wynikowy csv?

Idealnie by bylo w tym formacie: bo nie wszystkie pola mnie interesuja:

PROXY, TIMESTAMP, RESPONSE,TARGET_URL,TARGET_SERVICE,SERVICE , SESSION_ID
Input Proxy, 2013-11-11T14:15:48.133Z, Received some response, null, PANCAKE, All About You, dfgs2c4-0ba9-4ac3-8150-afa0b3596c59

jq -r '.hits.hits[]._source | [.proxy, .["@timestamp"], .response, .target_url, .target_service, .service, .session_id] | @csv'
