It would be convenient if the query DSL had some metadata component, so that we could tag queries. This would be useful in the case where certain queries are identified as being problematic (such as in the slowlog), and the origin in unknown. e.g., if Kibana could tag a query with the name of the visualization, it would make it simple to ID when there are, say, hundreds of visualizations.

GET /traffic-logs/_search
{
   "query": {
   },
   "size": 0,
   "meta": {
        "kibana_instance_id": "some_id"
        "kibana_dashboard_label": "My Deep Aggregations"
        "kibana_vis_label": "Error Codes by Country"
   },
   "aggs": {
   }
}
