How to get multiple values output from multiple fields with one _search request?

On a performance testing project where ELK stack is used to collect and process API test data streams(samples/document go under one index) it would be good if we could get multiple aggregated results with only one _search request, like the count of successful requests AND average response time AND various percentiles, etc. Is it possible to create such a DSL query or do we have to execute multiple searches like one to get the count of successful requests, another one for percentiles, etc?

you sure can, this page of the documentation gives an example, but here it is for reference;

curl -X GET "localhost:9200/my-index-000001/_search?pretty" -H 'Content-Type: application/json' -d'
{
  "aggs": {
    "my-first-agg-name": {
      "terms": {
        "field": "my-field"
      }
    },
    "my-second-agg-name": {
      "avg": {
        "field": "my-other-field"
      }
    }
  }
}
