You can try sub-aggregation:

 {

      "aggs": {

        "event_id": {

          "terms": {

            "field": "event_id"

          },

          "aggs": {

            "targetUser": {

              "terms": {

                "field": "tragetUser"

              },

              "aggs": {

                "ipAddress": {

                  "terms": {

                    "field": "ipAddress"

                  }

                }

              }

            }

          }

        }

      }

    }
