If you can't change the connector configuration you can use elasticsearch ingest pipeline to manipulate the incoming data.

#Create an ingest pipeline
PUT _ingest/pipeline/update_index_name
{
  "processors": [
    {
      "set": {
        "field": "_index",
        "value": "new_index_name"
      }
    }
  ]
}

#Put default pipeline to existing index
#make sure that your index name is proxy_http_trace. 
PUT proxy_http_trace/_settings
{
  "settings": {
    "index.default_pipeline": "update_index_name"
  }
}

#Push the data
POST proxy_http_trace/_doc
{
  "field": "test"
}
