I have this aggregation:

> ```
> {
> "query": {
> "range": {
> "time_stamp": {
> "lt": "now",
> "gte": "now-1d"
> }
> }
> },
> "size": 0,
> "aggs": {
> "events_by_host": {
> "terms": {
> "field": "cell_host_the_app"
> },
> "aggs": {
> "events_by_date": {
> "date_histogram": {
> "field": "time_stamp",
> "interval": "30m"
> },
> "aggs": {
> "total_cpu": {
> "sum": {
> "field": "cpu_usgae_percentage"
> }
> },
> "max_cpu": {
> "max": {
> "field": "cpu_usgae_percentage"
> }
> }
> }
> },
> "max_aggregated_cpu": {
> "max_bucket": {
> "buckets_path": "events_by_date>total_cpu"
> }
> }
> }
> }
> }
> }
>

I'm trying to figure out a way to return another field (called app\_name) from the max\_cpu sub aggregation that is performed. Is this possible?
